Production of AVGI-~ ~tjC Seed
The present invention relates to the production of genelically ~,dnsfo""ed plants. In particular
the invention relates interalia to a prucess for inducing apo",i~i~ to the apomictic seeds which
result from the prucess, and to the plants and progeny thereof which result from the gerrnination
of such seeds.
Apomixis which is vegetative (non-sexual) reproduction through seeds is a genetically
Cbr,t~ ed reproductive mechanism found in some polyploid non~ultivated species. The process
is 11assHiecl as gametophytic or non-ga",etophytic. In gametophytic apo",i~is - of which there
are two types (apospory and diplospory) multiple embryo sacs which typically lack anti~odal
nuclei are fomled or else megas~orugenesis in the embryo sac takes place. In adventitious
embryony (non-ga",et~,hytic apomixis) a so",atic embryo develops directly from the cells of the
embryo sac ovary wall or integuments. In advenmious embryony somatic embryos from
surrounding cells invade the sexual ovary one of the somatic embryos out~o",~etes the other
somatic embryos and the sexual embryo and utilizes the produced endo~pemm.
Were apomixis to be a controllable and reproduri~le pheno",enon it would provide many
advantages in plant improvement and cultivar dcvelûp",ent in the case that sexual plants are
available as crosses with the apom: ~ic plant.
For example apG""xis would provide for true-breeding seed prop~g~çd hybrids. Moreover,
apor,~ could shorten and simplify the breeding process so that selfing and progeny testing to
produce and/or stabilize a desirable gene combination could be eliminated. Apomixis would
provide for the use as cultivars of genotypes with unique gene comb ,al;ons since apomictic
genotypes breed tnue irrespective of heterozygosity. Genes or groups of genes could thus be
"pyramided and ~xed~ in super genotypes. Every superior apomictic genotype from a ssxual-
apomictic cross would have the potenlial to be a cultivar. Apomixis would allow plant b,eed~,r:, to
develop cultivars with specHic stable traits for such characters as height seed and forage quality
and maturity. E~reeders would not be limited in their co"""er ial production ot hybrids by (i) a
cytuplaamic-nuclear i,~t~ Aion to produce male sterile female parents or (ii) the fertility ~ t~lilly

capacity of a pollinator. Almost all cross~r"patil)le ge""pla~", could be a potential parent to
produce apomictic hybrids.
Finally, apo"-ixis would simplify coi-""er~idl hybrid seed production. In particular, (i) the need for
physical isolation of cG"""e.dal hybrid production fields would be eliminated; (ii) all available
land could be used to increase hybrid seed instead of dividing space between pollinators and
male sterile lines; and (iii) the need to maintain parental line seed stocks would be eliminated.
The pote.,lial benefits to accrue from the production of seed v7a apor"i,~is are presel,~ly
unrealized, to a large extent ber-suse of the pr~t'e " of engineering apomictic capacity into
plants of interest. The present invention provides a solution to that problem in that it provides
the means for obtaining plants which exhibit the adventitious embryony type of apu",ixii.
According to the present invention there is provided a method of producing apomictic seeds
co" ,~risi, ,9 the steps of:
(i) trd";,~o",ling plant material with a nucleotide sequence encoding a protein the
presence of which in an active fomm in a cell, or ,-,e"lt-,dne thereof, renders said cell
embryogenic,
(ii) regenerating the thus l,dn:,~u"ned ",ateiial into plants, or carpel-containing parts
thereof, and
(iii) ex~,ressi"y the se~uence in the vicinity of the embryo sac.
By Uvicinity of the embryo sac" is meant in one or more of the following: carpel, integuments,
ovule, ovule pre",G,.lium, ovary wall, chal~7~, nucellus, funicle and placellk~. The skilled man
will recognize that the term Uinteguments~ also includes those tissues, such as endothelium,
which are derived therefrom. By "embryogenic" is meant the capability of cells to develop into
an embryo under pe"";~ive conditions. It will be appreciated that the temm "in an active fomm~
indudes proteins which are truncated or otherwise mutated with the proviso that they initiate or
amplify embryugene:,i, v.h~tl,el or not in doing this they interact with the signal transduction
co""~onents that they ~: ,en,~;se would in the tissues in which they are normally present.
The temm ~plant ~"aterial" includes protoplasts, icolst~qcl plant cells (such as st.-n,a~al guard cells)
possçss;-,y a cell wall, pollen, whole tissues such as ellleryed radicle, stem, leaf, petal,

hypocotyl section, apical ",er,;il~"l, ovaries, zygotic embryo per se, roots, vascular bundle,
pericycle, anther filament, somatic emblyos and the like.
A further embodiment of the invention relates to a DNA molecule col"pris;"g a nucleotide
sequence encoding a protein the pr~sence of which in an active fomm in a cell, or ",e",brdne
thereof, renders said cell embryogenic.
The said nucleotide sequence may be introduced into the plant material, inter a~ia, via a bacterial
or viral vector, by micro-injection, by co-inc~h~tion of the plant material and sequence in the
presence of a high ",o'ec~ r weight glycol or by coating of the sequence onto the surface of a
biologically inert particle which is then introduced into the material.
Ex~.ression of the sequence may yield a protein kinase c,-~-'le of spanning a plant cell
membrane. Typically the kinase may be a leucine rich repeat ,~ce,ulur like kinase which has the
capacity to auto-phosphorylate. The skilled man will recognize what is meant by the temm
"leucine rich repeat receptor like kinase". Examples of such prute."s include Ar~ ~',pcis RLK5
(Walker, 1993), Ar~h~dop~is RPS2 (Bent et al. 1994), Tomato CF-9 gene product tJones et al.
1994), Tomato N (VVhitham et al. 1994), Petunia PRK1 (Mu et a/. 1994), the product of the
DrosophiJa Toll gene (I lashi",ùlo et al. 1988), the protein kinase encocJed by the rice OsPK10
gene (Zhao et al. 1994), the lldnslalion product of the rice EST clone ric2976 and the product of
the Drosophila Pelle gene (Shelton and Wasse""an, 1993). Still further examples of such
pr~t~ s include the TMK1, Clavatal, Erecta, and TMKL1 gene products from Arabidopsis, the
Flightless-1 gene product from DrDsophila, the TrkC gene product from pig, the rat LhCG
,eceplur and FSH receplor, the dog TSH receptor, and the human Trk ,eceptor kinase. The
protein may cG",~iise a ligand binding domain. a proline box, a trans",e"lb,dne domain, a
kinase domain and a protein binding domain. In many ,~ceptur kinases the extracellular (ligand
binding) domain serves as an inhibitor of the kinase domain in the ligand-free state. This arrest is
removed after binding of the ligand. Accordingly, in one embodiment of the invention the protein
either lacks a ligand binding domain or the domain is functionally inactivated so that the kinase
domain can be constitùtively active in the absence of an activating signal (ligand). Whebher or
not the protein posse~ses a ligand binding domain - full~,hulldl or ~I,en,~ e, once e~lessecl and
GIdted into the plant cell ",er"b,dne the protein binding domain is p~e~t:rdbly located
intra-cellularly.

In a p,~ "ecJ embodiment of the method, the said sequence further encodes a cell m~"lb,.lne
targeting sequence. The sequence may be that which is depicted in SEQ ID Nos. 1 2 20 or
32 or it may be similar in that it is complementary to a sequence which hyLridi~es under
st~i.,gen~ conditions with the said sequences and which enc~des a ",e"lL,dne bound protein
having kinase act~vity. ~y "similar~ is meant a sequence which is comp ~."ent~ry to a test
sequence which is capable of hybrdi~il,g to the inventive sequence. When the test and
inventive sequences are double stranded the nucleic acid constituting the test sequence
preferably has a TM within 20~C of that of the inventive sequence. In the case that the test and
inventive sequences are mixed togt:ll,er and denatured simultaneously, the TM values of the
sequences are prefe,~Lly within 10~C of each other. More pr~faldbly the h~,iJi~tion is
pe,lo""ed under sl,i"yenl con-litions with either the test or inventive DNA pref~r bly being
slJ~JpGIled. Thus either a denatured test or inventive sequence is preferably first bound to a
support and hyl,ridi~atior, is e~ 1ed for a specified period of time at a temperature of between
50 and 70~C in double ~t~r,ytl, citrate buffered saline (SSC) containing 0.1%SDS followed by
rinsing of the support at the same temperature but with a buffer having a reduced SSC
concent,alion. Depending upon the degree of ~t,i"gel,cy required and thus the degree of
similarity of the sequences at a particular lel"~,erdlure - such as 60~C for example - such
reduced concenl,dlion buffers are typically single sl,t:r,yth SSC containing 0.1%SDS half
~tlt:nglll SSC containing 0.1%SDS and one tenth st~ehytl, SSC containing 0.1%SDS.
Sequences having the y,eale t degree of similarity are those the hyb,idk~tion of which is least
affected by washing in buffers of reduced conceiltldtion. It is most pl~lerl~d that the test and
inventive sequences are so similar that the h~riWi~tion between them is substantially
unaffected by washing or incllh~tion in one tenth ~I,tr,gtl, sodium citrate buffer containing
0.1 %SDS.
Accordingly further cG"",rised by the present invention is a DNA sequence as depicted in SEQ
ID NOS: 22 24 26 28 and 30 or a sequence which is complementary to one which hybrh~kes
under sl,i"yeot conditions with the said sequences and which encodes a ",e"lbrc~ne bound
protein having Wnase activity.
The sequence may be modHied in that known mRNA instability motifs or polyadenylation signals
may be removed and/or codons which are p,efe"~:.l by the plant into which the sequence is to
be i, .se, led may be used so that e~r~ssion of the thus modHied sequence in the said plant may
yield suLs~rlti .I:y similar protein to that obtained by e~-~:ssiot) of the unmodified sequence in
the o,yani_." in which the protein is endogenous.

ln order to obtain ex~ 3s,0n of the sequence in the regenerated plant (and in particular the

pTA7001 inducible prullloten The DcEP3-1 gene is e~ressed lldns,antly during inner
integument degradation and later in cells that line the inner part of the dcv~ F: ,g encJospel"l.
The AtChilV gene is lldl~5i~:"Uy e~r~ssed in the micropylar endospemm up to cellularisation. The
LTP-1 prulllolt:r is active in the epide,lll;s of the dcv~F.I9 nucel~ both integuments seed
coat and early embryo. The bel-1 gene is e,~ressed in the dc~elop;. I9 inner integument and the
fbb-7 promoter is active during embryo sac dc-.relopment. The Ar~h;dop~ ANT gene is
expressed during integument dcveloprl,en~ and the 0126 gene from Phalaenopsis is e~r~:ssed
in the mature ovule.
It is most p.efe"t:d that the sequence is ex~uressecl in the somatic cells of the embryo sac ovary
wall nucellus,orinteguments.
The endospemm within the apomictic seed results from fusion of polar nuclei within the embryo
sac with a pollen-derived male gamete nucleus. It is preferred that the sequence encoding the
protein is e~r~secl prior to fusion of the polar nuclei with the male gamete nucleus.
The invention further includes a DNA but prt:lerably a recombinant DNA co-."~rs;"g a
sequence encoding a protein the presence of which in an active form in a cell or ~e~lb~ane
thereof, renders said cell embryogenic. Preferred is a DNA encoding a protein which is a leucine

a protein having the sequence depicted in SEQ ID Nos. 3 or 21, or a protein subsk~Antially similar
thereto which is capable of being nle"lb,dne bound and which has kinase activity. By
s~ Antially similar is meant a pure protein having an amino acid sequence which is at least
90% similar to the sequence of the prut~ i. ,s depicted in SEO ID No 3 below. In the context of
the present invention two amino acid sequences with at least 90% similarity to each other have
at least 90% identical or conservatively replnced amino acid resi~ues in a like position when
aligned optimally allowing for up to 8 gaps with the prDWso that in respect of each gap a total not
more than 4 amino acid residues is affected. For the purpose of the present invention

It is pl~fe~ d that the DNA further encodes a cell ",e"lb,dne ~ryetillg sequence and that the
protein encoding region is under exur~s~ion control of a dcv .lop",enldlly rerg~' ted or inducible

As indicated above the DNA may be modffied in that known mRNA instability motffs or

Comprised within the scope of the present invention are transgenic plants, in particular
transgenic fertile plants transformed by means of the aforedescribed processes and their
~ceyu~l and/or sexual progeny, which still contain the DNA stably incorporated, and/or the
apomictic seeds of such plants or such progeny.
The transgenic plant according to the invention may be a dicotyledonous or a
monocotyledonous plant. Such plants include field crops, vegetables and fruits including
tomato, pepper, melon, lettuce, cauliflower, ~,oc~, ', r~hb~ge, bnussels sprout, sugar beet,

from u"l.dr,a~o".,ed like crops. Preferred are monocotyledonous plants of the
Gra""naceae family involving Lolium. Zea. Tnticum. Triticale, Sor~hum. Saccharum,
Bromus. Oryzae. Avena. Ho~eum, Secale and Setaria plants.
More preferred are transgenic maize, wheat, barley, sorghum, rye, oats, turf and forage
grasses, millet and rice. Especially preferred are maize, wheat, sorghum, rye, oats, turf
grasses and rice.
Among the dicotyledonous plants Arabidopsi~, soybean, cotton, sugar beet, sugar cane,
oilseed rape, tobAcco and sunflower are more preferred herein. Especially preferred are
soybean, cotton, tob~cco, sugar beet and oilseed rape.
The expression 'progeny' is understood to embrace both, "asexually" and "sexually"
generated progeny of transgenic plants. This definition is also meant to include all
mutants and variants obtainable by means of known processes, such as for example cell
fusion or mutant selection and which still exhibit the characteristic properties of the initial
transformed plant, together with all crossing and fusion products of the transformed plant
material. This also includes progeny plants that result from a backcrossing, as long as
the said prugeny plants still contain the DNA according to the invention
Another object of the invention concerns the proliferation material of transgenic
plants.
The proliferation material of transgenic plants is defined relative to the invention as any
plant material that may be propagated sexually or asexually in vivo or in vitro. Particularly
preferred within the scope of the present invention are protoplasts, cells, calli, tissues,
organs, seeds, embryos, pollen, egg cells, zygotes, together with any other propAgAting
material obtained from l,dnsgenic plants.
Parts of plants, such as for example flowers, stems, fnuits, leaves, roots oriy;lldlillg in
transgenic plants or their progeny previously transfommed by means of the process of the
invention and therefore consiali"g at least in part of transgenic cells, are also an object
of the present invention. ~speically pr~ft,r,~d a apomictic seeds.
A further object of the invention is a ",ell,ocl of producing apomictic seeds, but pl~ b~

embryogenic, but preferdbly a protein which is a protein kinase capable of spanning a
plant cell ",e"ll,,dne and -~F~ Of autophospho~lation.
(ii) regeneraffng the thus l,d"slo",-ed ",alerial into plants, or carpel-conl..i.,;.,y parts
thereof, and
(iii) ex~,es~i"g the sequence in the vicinity of the embryo sac.
The kinase protein being expressed by the DNA accordi.,g to the invention is preferably a
leucine rich repeat receptor like kinase and co"~iises a ligand binding domain, a proline box, a
t,cln~",e",brdne domain, a kinase domain and a protein binding domain. In a specHic
embodiment of the invention, the said kinase protein may lack a functional ligand binding
domain but comprises a proline box, a t,~n~",t:"lL,tdne domain, a kinase domain and a protein
binding domain.
The genetic properties engineered into the transgenic seeds and plants described above
are passed on by sexual reproduction or vegetative growth and can thus be maintained and
prop~g~ted in progeny plants. Generally said maintenance and prop~g~tion make use of
known agricultural methods developed to fit specific purposes such as tilling, sowing or
harvesting. Specialized processes such as hydroponics or greenhouse technologies can
also be applied. As the growing crop is vulnerable to attack and damages caused by insects
or infections as well as to competition by weed plants, measures are undertaken to control
weeds, plant diseases, insects, nematodes, and other adverse conditions to improve yield.
These include mechanical measures such a tillage of the soil or removal of weeds and
infected plants, as well as the application of agrochemicals such as he,L.~ ~es, fungicides,
gametocides, ne".~li.;des, growth regulants, ripening agents and ir secticides
Use of the advantageous genetic properties of the transgenic plants and seeds according to
the invention can further be made in plant breeding which aims at the develop",6,lt of
plants with improved pr~pe,lies such as t~'Erdnce of pests, herbicides, or stress, improved
nutritional value, increased yield, or improved structure causing less loss from lodging or
shall~F" ,g. The various breeding steps are chardl,t.,F,~:d by well-de~i"ed human
intervention such as selecting the lines to be c,ussed, directing pollination of the parental
lines, or selecting apprupriate progeny plants. Dependi"g on the desired properties difl~
breeding measures are taken. The relevant techniques are well known in the art and include
but are not limited to hyL"idi~dtion, inbreeding, backcross breeding, multiline breeding,

CA 022~4839 1998-11-13
WO 97/43427 PCT/EP97/02443

variety blend, interspecific hybridization, aneuploid techn :,ues, etc. Hybticii~a~ion
techniques also include the :,le~ tion of plants to yield male or female sterile plants by
mechanical, chemical or biochemical means. Cross pollination of a male sterile plant with
pollen of a different line assures that the genGi"e of the male sterile but female fertile plant
will uniformly obtain properties of both parental lines. Thus, the transgenic seeds and plants
according to the invention can be used for the breeding of improved plant lines which for
example increase the effectiveness of conventional methods such as herbicide or pestidice
treatment or allow to dispense with said methods due to their modified genetic properties.
Alternatively new crops with improved stress tolerance can be obtained which, due to their
Gpli",i~ed genetic "equi~,",enl~, yield harvested product of better quality than products which
were not able to tolerate comparable adverse develop",ental condilions.
In seeds production germination quality and uniformity of seeds are essential product
chara~terislics, whereas germination quality and unilGIlllity of seeds harvested and sold by
the farmer is not important. As it is difficult to keep a crop free from other crop and weed
seeds, to control seedborne diseases, and to produce seed with good gerrnination, fairiy
extensive and well-defined seed production prclctices have been developed by seed
producers, who are experienced in the art of growing, conditioning and marketing ot pure
seed. Thus, it is cG"""on practice for the farmer to buy certified seed meeting specific
quality standards instead of using seed harvested from his own crop. Prop~tion material
to be used as seeds is customarily treated with a protectant coating co",pris,ng he,l,i~ ides,
insecticides, fungicides, bactericides, nematicides, molluscicicles or mixtures thereof.
Customarily used protectant coatings comprise compounds such as captan, calL,o~-i",
thiram (TMTD~), methalaxyl (Apron6), and pirimiphos-methyl (Actellic-). If desired these
compounds are forrnulated together with further carriers, surfactants or application-
prul"oti"9 adjuvants customarily employed in the art of formulation to provide prulection
against damage caused by bacterial, fungal or animal pests. The p~le~ l coatings may
be applied by i""~fey"ati"g propq.~qtion material with a liquid formulation or by coating with
a combined wet or dry formulation. Other ",ell,ods of application are also possible such as
treatment directed at the buds or the fruit.
It is thus a further obiect of the present invention to provide plant prop~g~qtion ",dl~ial for
cultivated plants, but e~peciqliy plant seed that is treated with an seed proteclant coating
customarily used in seed treatment.

lt is a further aspect of the present invention to provide new agricultural methods such as
the methods examplified above which are characterized by the use of l~dnsgenic plants,
~,dnsgeni~ plant material, or l~,-sgenic seed according to the present invention.
To breed progeny from plants transformed according to the method of the preserltinvention, a method such as that which follows may be used: plants produced as des~;,ibecl
in the examples set forth below are grown in pots in a greenhouse or in soil, as is known in
the art, and permitted to flower. Pollen is obtained from the mature stamens and used to
pollinate the pistils of the same plant, sibling plants, or any desirable plant. Similarly, the
pistils developing on the transforrned plant may be pollinated by pollen obtained from the
same plant, sibling plants, or any desirable plant. Trdns~ur,,,ed progeny obtained by this
method may be distinguished from non-transformed progeny by the presence of the
introduced gene(s) and/or acco",panying DNA (genotype), or the phenotype conferred.
The transformed progeny may similarly be selfed or crossed to other plants, as is nommally
done with any plant carrying a desirable trait. Similarly, tob~cco or other transformed plants
produced by this method may be selfed or crossed as is known in the art in order to
produce progeny with desired characteristics. Similarly, other transgenic o.yariis",s
produced by a combination of the methods known in the art and this invention may be bred
as is known in the art in order to produce progeny with desired chara~:terixtics.
Further co",pr,aed by the invention is a method of obl~i";"g embryogenic cells in plant material,
colllpri:.;"g b~rls~GI"ling the ",c-terial with a recombinant DNA sequence or a vector according to
the invention, ex~rt:s~"~g the sequence in the material or derivatives thereof and subjecting the
said mate,ial or derivatives to a compound which acts as a ligand for the gene product of the
said sequence.
The invention further relates to a method of generating somatic embryos under in vitro
cor,diticins wherein the SERK protein is overexpressed ~ - - F .c ~y.
The invention still fur~er indudes the use of the said DNA in the manufacture of apomictic
seeds, in which use the sequence is e~r~ssed in the vicinity of the embryo sac.
In a specific embodiment of the invention the SERK gene may be e~ressed in l,dr,sgenic plants
such as, for example, an Arab~dopsis plant, under the control of plant e~r~sa;~,n signals,
particula~y a pru",~ter which regulates e~rt:ssion of SERK genes ~n plan~a, but prt:fe,cb~f a

developr"e"L"y regl~l?tecl or inducible pru",ote, such as for example. the carrot chitinase
DcEP3-1 gene p,u",ùter, the Ara~ rsis AtChitlV gene prc ",~ter the Arah_lop~is LTP-1 gene
p,u.l,citer the Arabidopsis bel-1 gene pru,,,ùler the petunia fbp-7 gene prc".,-~ter the
Arabidopsis ANT gene pru",oter or the pru,,,ù~er of the 0126 gene from rl~ldenopsis, the
Arabidopsis AtDMC1 p,o,..~ter, or the pTA7001 inducible p~u~ut~r.
The pru",ot~,~ of the DcEP3-1 and the AtChit IV genes may be cloned and characterized by
standard procedures. The DcSERK coding sequence (SEQ ID No. 2) is cloned behind the
DcEP3-1 the AtChit IV or the AtLTP-1 prw.,oters and tran~to~",ed into Arahic~l~pc;s The ligation
is pe,lo""ed in such a way that the p,c""oter is operably linked to the sequence to be
l.dnsc,iiJed. This construct which also contains known marker genes providing for selection of
transformed material is inserted into the T-DNA region of a binary vector such as pBlN19 and
transformed into Ara~ 10p-~;s Agr~b2cteriutr1mediated translo-",ation into Ar~J~Or~jS jS
performed bythe vacuum i"~iltl~tion or root l,dr,:,~o""ation procedures known to the skilled man.
T-dr~ o"-,ed seeds are selected and harvested and (where possible) I,~ns~u""ed lines are
established by nomnal selfing. Parallel l-~r~ u""alions with 35S prù",oter-SERK constructs and
the entire SERK gene itseH are used as controls to evaluate over-ex,Jression in many cells or
only in the few cells that naturally express the SERK gene. The 35S p,u",uler-SERK construct
may give embryo forrnation wherever the signal that activates the SERK-",edialed transduction
chain is present in the plant. A testing system based on em~sc~ tion and the generation of
donor plant lines for pollen carrying LTP1 pru",oter-GUS and SERK pru",oler-bamase is
established.
The same constructs (35S, EP3-1, AtChitlV AtLTP-1 and SERK ~pru",ote,~ fused to the SERK
coding sequence) are employed for l,."~:,lo""ation into several A~ 'cp.~is backgrounds. These
backgrounds are wild type, male sterile fis (allelic to emb 173) and pri",o,dia timing (pt)-1 lines
or a combination of two or several of these backgrounds. The wt lines are used as a control to
evaluate possible effects on normal zygobc embryogenesis and to score for seed set u~out
fertilization after errasc~ Qn. The ms lines are used to score directly for seed set without
fertilizabon. The fis lines exhibit a certain degree of seed and embryo dcv.Jlopr.,6rlt without
fertilization so may be expected to have a natural l~nden~y for apomicbc embr~,ugenes,-, which
may be enl)anced by the p,esence of the SERK constructs. The pt-1 line has superior
,tz~ene~ e capabilibes and has been used to initiate the first stably embryogenic Ara~idûpsis
cell suspension cuttures. Comb:.,ations of several of the above backgrounds are obta;.,ed by

crossing with each other and with lines containing ectopic SERK ex~.essi"g constnucts. Except
for the ms lines, prop~g~tion can proceed by nommal selfing, and analysis of apomictic traits
;ng em~sculetiQn. A similar strategy is followed in which the ATChilV, AtLTP-1 and SERK
p,u",~,le,~ are replece~l by the bel-1 and fbp-7 pru."~te,~ as well by other plulllotela specHic for
cGIllpol)êllls of the female gal"eto~,l,yte.
Additional constructs are generated that have constitutive rèce~.lur kinase activity. Most of the
~eceplor kinases of the SERK type act as homodimeric receptors, requiring aulo~hoaphorylation
before being able to activate do.~.,sbeam signal transduction c~sc~les In many ,ecep~,
kinases the extracellular domain serves as an inhibitor ot the kinase domain in the ligand-free
stage. This arrest is removed after binding of the ligand (Cadena and Gill, 1992). By introduction
of a SERK construct, from which the extracellular ligand-binding domain has been removed,
mutant homodimeric (in cells that do not have a natural population of SERK pr~t~,i"s) or
heterodimeric (in cells that also express the u"",odified forms) pr~t~,i.,~ can be generdted with a
constitutively activated kinase domain. This approach, when coupled to one of the prul,,olera
active in the nucellar region, results in activation of the embryogenic pathway in the absence of
the activating signal. This may be an i",~)o,lanl altemative in cases where it is necess~ry or
desirable to have activation of the SERK pathway only dependant on specific pn.",oter activity
and independent of telll~Joldl re~ulation of an activating signal. Introduction of SERK constructs
that result in fertilization-independent-embryugene~;s (fie) are tested in other species for their
effect. In order to recognize the fie phenotype, the skilled man will use appr~,prial~ male sterile
backgrounds. 1 lo.~e~/cr, pollination is often necess~ry for apo" ,i~is of the adventitious embryony
type, in order to ensure the production of endosperrn.
Whilst the present invention has been particulariy des~"iL,ed by way of the production of
apomictic seed by hel~rc'clgous ex~,r~ssion of the SERK gene in the nucellar region of the
carpel, the skilled man will recognize that other genes, the products of which have a similar
structure/function to the SERK gene product, may likewise be eA~ur~ssed with similar results.
Moreover, aithough the example illustrates apomictic seed production in AQbrdopsis, the
invention is, of course, not limited to the eA~ ssion of apomictic seed-inducing genes solely in
this plant. Moreover, the present r~icclQsure also includes the possibiiity of eA~ s;"g the SERK
(or related) gene sequences in the l,d"~u""ed plant material in a constitutive - tissue non-
specific ",anner (for example under l,dns~ onal control of a CaMV35S or NOS pru,,,oter). In
this case, tissue spe~,ifi.,ity is as-cured by the loc~ d p,~sence within the vicinity of the embryo

W 097/43427 PCT~EP97/02443
sac of the ligand of the product of the said gene. Furtherrnore the SERK (or related) gene
products may interact with prutei.,s such as trans..,i~,ti~n factors which are involved in regulating
embryogenes;a. This i~,lerdction within tissue which has been l,ar,~u,,,,ed according to the
present ~iicclosure is atso part of the present invenbon.
The skilled man who has the benefit of the present ~isclos~ ~re will also recog"i~e that the SERK
gene (and others as indicated in the preceding paragraph) may be l,an~lo"l,ed into plant
material which may be propagat~d and/or dff,e,~,ltialed and used as an explant from which
somatic embryos can be obtained. Ex~re:ssion of such sequences in the translu,,,,ed tissue
(which is subjected to a ligand of the kinase gene products) suL,~lantially i~l~ reases the
percentage of the cells in the tissue which are competent to form SGI I latic embryos, in
co"lparison with the number present in non-l,dnsfui-"ed like tissue.

Figure 1 shows the results of an RT-PCR experiment pe,~u,,,,ed on RNA extracted from the
indicated tissues. 40 cycles f~ l~wsd by Southem blotting of the resulting bands is necess~y to
visualize SERK e,~ ssion. Lanes include e~la,lt~ at day 7, treated for less (lane 1) or more
(lane 2) then 3 days with 2,4-D. In the original a very faint signal is visible in lane 2 but not in
lane 1. Established embryogenic cultures (lanes 4 6) but not a non-embryogenic control (lane 3)
eA~,r~ss the SERK gene. In carrot plants no ex~ ssion is dete - ~ except for developing
seeds after pollination (lane 7). Up to day 7 after pollination, the carrot zygote ,t:" ,ai"s u, IJiii;led,

ISOLATION AND CLONING OF THE SERK GENE FROM DAUCUS CAROTA
Isolation of cDNA clones that are ,u,~F~,.a-~rially O~ eSSli~ in embryogenic cell cultures of
carr~t
In order to increase the chance of success for obtaining genes eA~ ssed in carrot suspension
cells competent to fomm embryos, the number of embryo-forming celis as present in a series of
established cell cultures was determined. A sub-poru'-tiQn of cells that passed through a 30 mm
nylon sieve was isolated from eight di~e,t:rll cultures that ranged in age between 2 months and
4 years. In these sub 30 mm pop~ tions, the number of embryos fommed from the single cells
and small cell clusters was detemmined and eA~,ressed as a pe,.;entage of the total number of
cells present at the start of embryogenesis. Sieved ~30 mm cultures able to fomm somatic
embryos with a frequency of more than 1% were then used as a source for competent cells, and
cultures that produced less than 0.01% embryos were used as non-embryogenic controls. As
main cloning strategies, cold plaque screening (Hodge et al. 1992) and di~e,~r,lial display (dd)
RT-PCR (Liang and Pardee, 1992) were used besides conventional differential screening of
cDNA libraries.
I ~heled probes for di~le,~:nlial screening were obtained from RNA out of a c30 mm sieved
sub-pop~ tion of cells from either embryogenic or non-embryogenic cell cultures. Employing
these probes in a library screen of al~pruA,, ,,ct~,ly 2000 plaques yielded 26 ~ ues that failed to
show any hyL li, li~dtion to either probe. These so-called cold plaques were purified and used for
further analysis. From the total number of p!-ques that did hybridize, about 30 did so only with
the probe from embryogenic cells. ddP~T-PCR reactions using a combination of one anchor
primer and one cleca",er primer were pel~ lled on mRNA isolated from three embryogenic, and
three non-embryogenic su~ ensiol1 cultures. About 50 d~le,~nt ddRT-PCR fragments were
obtained from each reaction. Using co"d,;.,dl,ons of three di~lert:nt anchor and six .li~ .)t
clec~-,-er primers, a total of a~ ~,ruAi."dt.,ly 1000 different cDNA lldylllents was ~cl~ 7ed Six of
these PCR l,.ly",e"~ were only found in lanes made with mRNA from ~30 mm popu'-tiQns of
cells from embryogenic cultures (Table 1 ) and with oligo comb: ,aUons of the anchor primer (5'-
11111111 1 l IGC-3') and the deca",el primers (5'-GGGATCTMG-3'), (5'-ACACGTGGTC-3~,
(5'-TCAGCACAGG-3~. Rec~use differential PCR fragments often consist of several ~ulr~soh~0d
cDNA fragments (Li et a/. 1994), cloning proved to be esse"~idl prior to undertaking further
char~-,le,i~tion of the PCR fragments obtained.

All clones obtained were subjected to a second screen that consi~lad of spot-dot Northem
hyl,F"~ lion pe,~o""ed under conditions of high ~I,i"gen~. This method, that used RNA from
entire unsieved embryogenic and non-emb~ogenic sus~ansion cultures, proved to be a fast and
reiiable additional scl~tion method. Only one clone (22-28) of the 30 clones obt~i"ed after
differential screening proved to be ,~-~I,i~ad to embryogenic cell cultures while the majonty was
constitutively eA,u,~ssed. The 26 clones obtained from the cold plaque sc,t:en..,g required long
exposure times in the spot-dot Northem analysis. Six of these clones failed to show any
hyl,r,Ji~ation signal and 19 proved to be e~ressed in both embryogenic and non-embryogenic
cell cultures. One clone (31-50) showed low e~r~Kion in all embryogenic cultures and in one
non-embryogenic culture but not in the others. Of the six cloned fragments obtained by ddRT-
PCR display four showed hyl,ridi~a~ion more or less ,~sl,i-Aad to bdns~ ,t~ present in
embryogenic cultures. All clones that passed through the second screening were sequenced.
Two of the ddRT-PCR clones (6-8 and 7-13) were identical to the carrot Lipid Transfer Protein
(LTP) gene previously identffied as a marker for embryogenic carrot cell cultures. LTP
e~r~s,on is rt:~l,ic~t:d to embryogenic cell clusters and the p,ulude"" of somatic and zygoffc
embryos from the early globular stage onwards (Sterk et al. 1991). Therefore while the LTP
gene is not a marker for competent cells its appearance in the screening corlIi""s the validity of
our methods with respect to the cloning of genes exl.ressed early during somaticembryogenesis.
cDNA clone 31-50 e..codes a leucine-rich repeat containing ,~;cep~or-like kinaseThe mRNA co"~spGIlding to the isolated clone 31-50 had an open reading frame of 1659
nucleotides encoding a protein with a c~ ted Mw of 55 kDa. Rec~l-se clone 31-50 is mainly
e~,essed in embryogenic cell cultures it was .t:na",ecJ Somatic Embryogenesis Receptor
Kinase (SERK). The SERK protein co"tai"5 a N-temninal domain with a five-times l~peS~t~CI
leucine-rich motif that is pruposed to act as a protein-binding region in LRR ~t:ceptor kinases
(Kobe and Dcisenbofer, 1994). Between the extracellular LRR domain of SERK and the
~e~llb~dne-spanning region is a 33 amino acid region rich in prolines (13), that is unique for the
SERK protein. Of particular interest is the sequence SPPPP, that is conserved in extensi"s, a
cla~ of universal plant ceU wall ~,rut~ ;.,s (Vamer and Lin, 1989). The p,uposed intracellular
domain of the protein c~lltaills the 11 subdomains cl,a,a- I~F,~tic of the catalytic core of protein
kinases. The core sequences HRDVKAAN and GTLGYIAPE in ~*cpec,i~/ely the kinase
subdomains VB and Vlll sugge.st a function as a serine / threonine kinase (I tanks et al. 1988).

Another i"lere~ g feature of the intracellular part of the SERK protein is that the C-terrninal 24
amino-acids resembles a single LRR. The serine and threonine r~sidues present within the
intracellular LRR sequence are surrounded by acidic residues and might be targets for the
autophosphorylaffon of SERK, thereby regulating the ability of other ~,,ote;.,s to interact with this
receptor-kinase in a similar fashion as desc,il,ed for the SH2 domain of the EGF family of
tyrosine receptor kinases.
Hybridi~ation of the SERK cDNA clone to the carrot geno",e revealed the pr~:sence of only a
single main hy~ndi~i- ,9 band after digestion with EcoR1, ,crubaLly ~~cfle~til ,9 a single SERK gene
in the carrot genome. This was confirrned after digestion with Ddel an enzyme that cuts three
times within the SERK gene. No signal was observed after N~.lhelll blotting of mRNA from
embryogenic cell cultures and hyl,ridi~clion with labeled SERK probes ,~:fle~ti"g the low levels
of l,dnsc,i~JI present in these cultures. Detection of the SERK l,dns~ l on the original spot-dot
Northems was only possible after long exposure times compared with other probes.
The ability of the SERK protein to autophosphorylate was inve~ ti-J~d in vitro using a previously
desc,iL,ed au~ophospholylation assay (Mu et al. 1994), with a l~a~ nal fusion protein that
contained the con,pete intracellular region of the SERK protein. The bacterially eA~.r~sse.l
SERK fusion protein was able to autopho- ~.horylate, indicating that the SERK protein is able to
fulfill a role as a protein kinase in vivo (Heldin 1995).
C~,r~:ssiG" of the SERK gene cG--~;ponJs with the first ~pez.~.lce of CG~ t~.~l cells
during hypocotyl activation
When carrot hypocotyls are induced with 2,4-D, only the cells of the provascular tissue
proliferate. Cells of epidemmal and cortical origin merely expand suggesffng that the provascular
tissue derived cells fomm the newly initiated suspension culture. After removal of 2 4-D, the
fo""dlion of SGIlldlic embryos occurs after 2-3 weeks. Somaffc embryos are prt:cedPd by
embryogenic cells that are dcveloped in tum from co.ll~ctenl cells. While col..~.ete~lt and
embryogenic cell fo""alion take place in the p,.,sence of 2,4-D, it was not clear when this
occurred and which cells acquired co",petence. Since previous e;~t:,i",ents (Toonen et al.
1994) revealed that cell ll,o"ul,r~yy is not a good criterion, the first appeard,)ce of single
competent cells was detemmined e~er""erltdlly by semi-automaffc cell hdcl~illg pe,f~""ed on
large pop~ tions of immobilized cells. Hypocotyl e.~l,hnt~ activated with 2,4-D for seven days
were mecl,an ~lly f-dy",ent~d and samples of the resulffng popu'~ion of mainly single

suspension cells were immobilized to aliow recording of their dcv~lopment by cell tracking. In the
immobiiized cell pop~tions obtained in this way all the morphologically discemible cell types
were present that were also seen in the un-l,ay",enled activated hypocotyls. Rec~l ce the
different cell ~ vh~cgies observed during hypocotyl activation were known (Guzzo et al.
1995), it was possible to trace back the original posibon of each type of cell in the activated
explant. Small cytoplas",-rich cells (16x16 mm) are the proliferating cells that surround the
vascular ele",erlt~. Enlarging v~cuol~ted cells (16x40 mm) are encountered on the surface of
the mass of prolHerating cells and these can detach from the surface when fully enlarged (35x90
mm). Large v~cuoQted cells (more than 60x140 mm) are the non-proliferating ~"",ar,ls of the
hypocotyl epidemmis and cortical parenchyma. The shape of the enlarging and fully enhr~Jed
cells could change from oval to elongate or triangular. Cell tracking on a total of 24 722 cells
,~le~P from seven days activated hypocotyls showed that only 20 single cells fommed a
somatic embryo. Bec~se of their dependance on continued 24-D treatment the embryo-
fomming single cells are still in the competent cell stage. All of the embryo-fomming single cells
belonyecl to the category of 3 511 enlarged cells that contained therefore competent cells in a
frequency of 0.56%. The single cell tracking ex~.e,i",ent~ clea~y reveal that the ability of explant
cells to reinitiate cell division under the influence of 2 4-D resulting in a popu ation of highly
cytuplasn,ic and rapidly proliferating cells does have a causal relation with the ability to become
embryogenic. It is also clear that only a very limited number of the cells that make up the newly
initiated embryogenic suspension culture are actually competent to forrn embryogenic cells.
E3 ~J,ession of the SERK gene detemmined by whole mount in situ h~,L,ridi~lion on a similar
population of cells as used for the cell tldcl~illg experi",ent~ was found to be ~e:S~ ed to only
0.44% of the enla.yed cells. There~urt:, the ex~rt:ss,on of the SEP~K gene appears closely
cc",elalt:d both qualitatively and quantitatively with the p,t:sence of col-")ete.)l single cells.
To obtain insight into the teillpoldl reg~l~tion of SERK ex~ression in the course of explant
activation whole mount 'n s~u hybridization was pe.fu....ed on enbre intact or hand-sectioned
eA~la"t~ treated for different periods with 2 4-D. n_"r~sen~ti.re samples were ~ E~ted at daily
intervals from eA~Jlants u, ~ ated and treated for three days six days, seven days or ten days
with 2,4-D before retuming to B5~. No SERK-ex~ ssi"g cells were ever found in e~larlts
treated for less then three days with 2,4-D. While enla.yed cells became present after the first
five days of culture the first few SERK-eA~rt:ss,.,y enldryecJ cells were found after six-seven
days of culture in the p-t,sence of 2 4-D l,.adt~-,enl. These few cells were present at the surface

of the mass of pr~';.erdli"g cells originating from the provascular tissue. In the hypocotyls treated
for ten days with 2.4-D the number of SERK-positive cells had i".;,~ased to 3.04% and included
at this stage also cells present in small clusters. No SERK t~ans~ t was ever cJet~ct~d in small
cytoplas" ,-rich cells or large v~cuol-'ed cells. Hypocotyls were also treated for only one day with
2 4-D and s~ Ihse~uently cultured in ho" "one-free medium for a total of seven or ten days. Under
these conditions explant cells proliferated and gave rise to roots and non-embryogenic cell
cultures while SERK e~ r~ssion could never be clel~d The in situ hy~"idi~lion results
des~,iL,ed above were obldi"ed from a relatively small number of ex~la"t~ and a few hundred
cells so RT-PCR followed by Southern hyb,idi~tion was pe~i~"",ed to obtain more quar,lit~iJc
results. These are shown in Figure 7 and confimm the close l~ oldl co"~lation between the first
a~eardnce of competent cells in e~,ta"l; treated for three days with 2 4-D and the eA~ sa;on
of the SERK gene. Northem hyL"idi~tion never gave any signal after hyL,ricli~tion with SERK
cDNA probes, not even after prolonged exposure in a Phosphorlmager in line with the
extremely re~ ;ted ex~.ression pattem of the SERK gene.
~.ress,~n of the SERK gene cGI~es~Gl~Js with the occumnce of CGI~I~t~.~t cells in
established embryogenic cell cu~tures
While the results described so far indicate that co",pelent and embryogenic cell fG""alion is
le:slli~1ed to a particular class of enlarged cells during explant activation ~he situation in an
established embryogenic cell culture is more complex. Colll~ etcnt single cells in such cultures
do not appear to belong to one cell type in particular but have been shown to originate from all
morphologically different cell types. In cell tracking experi",ent~ embryogenic cells that do not
require exogenous auxin l,t:al,.,enl were never observed to be single but consiilad of clusters
of at least 34 cells (Toonen et al. 1994). SERK e)~ s:,ion was found in all ,,,o,~uh-'ogically
discemible single cell types that were present in an embryogenic cell culture at a frequency
between 0.1 and 0.5% depending on the cell type. In non-embryogenic cultures SERK
e3~ s~i.,g cells were never encountered. As was observed in the activated e~Jh.lt~, SERK
ex~ression was not It:atli-,ted to single cells, but also occurred in small clusters of 2 to 16 cells.
Since clusters of this size are known to consist of embryogenic cells, these data show that
SEP~K e,~ ss;on is not l~tli~ed to co""~elent single cells but may persist in small clusters of
embryogenic cells. No SERK ~ ,r~:,sion was encountered during the late globular, heart and
to" ed~t-ges of somatic embryogenesis.

The SERK gene is t.~,.si~,ltly eA~,-essed in zygotic embryoge.)esis
The eApre,s,ion of the SERK gene in carrot plants was detemnined by RT-PCR. The results
indicate that no SERK mRNA accumulates in any of the adult plant organs nor in flowers prior to
pollination. The first oc~Acion when SERK eA~ression can be d~t~ . ~d is in flowers at three days
after pollination (DAP), at which stage fertilization has taken place and endosperm develo~," ,ent
has co"""enced. SERK mRNA remains present in flowers up to twenty DAP CO"t,S~ onding
with the early globular stage of the zygotic embryo (Yeung et al. 1996~. Whole mount in sitv
hybridi~ation on partially ~;~e~;ted carrot seeds cc"fi""ed that the SERK gene was only
eA~ ssed in early embryos up to the globular stage. ~ulêssion was observed in the entire
embryo including the sus~ensor. No eA~,ress;ol- was seen in seedlings roots stems leaves
dev~hr: lg and mature flower organs pollen grains and stigma's before and after fertilization.
rlssues in the dcv~leF: Ig seed such as seed coat integuments all embryo sac constituents
before fertilization as well as the endosperm at all stages of dc~/_lop",e"l inves~i-3~Qd did not
show any SERK eAurt:ssion. Later stages of carrot zygotic embryos were also cGIll~!ut~.ly devoid
of SERK mRNA. Given this pattem of eA~,ression that is re~l,i.~ed to the zygotic embryo, the
signal as d~le.1ed by RT-PCR in flowers at 3 and 7 DAP must come from SERK mRNA as
present in zygotes because in carrot the zygote It~ ls undivided up to one week after
pollination (Yeung et al. 1996). Although SERK eA~ ssion persists to slightly later stages in
zygotic globular embryos when compared to the somatic ones these results confimm the
l,dns,anl pattern of expression as observed for the SERK gene during somatic embryugene~
and also imply that there is a correspondence between the fo""ation of competent cells in vitro
and the fo""ation of the zygote in vivo.
METHODS
Cell culture, hypocotyl explant induction and cell llacki~ly
Cell cultures were derived from Daucus car~ta cv. FlaWcese and maintained as previously
described (De Vries et al. 1 988a). Cell su:" ension cultures were maintained at high cell density
in B5 medium (Gamborg et al. 1968) s~ leh,erlted with 2 mM 2 4-D (B5-2 medium). Embryo
cultures with globular heart and torpedo-stage somatic embryos were derived from <30 mm
sieved cell cultures cultured at low cell density (100 000 cells / ml) in B5 medium without 2,4-D
(B5-0). For hypocotyl explant induction e~eff",-:nt~ phr,tle~ were obtained from seed of

Daucus car~ta cv. S Valery as cles~ ed previously (Guzo et al., 1994). The hypocotyls of one
week old plantlets were divided in seylllellLa of 3-5 mm inc~hA~ed for various periods of time in
B5-2 medium and retumed to B5-0 medium. Seven days after ex~lantdIion and exposure to 2,4-
D the hypocotyl seylll~lltà were Ildy,l,er,l~d on a 170 mm sieve and the resulting cells ~ "e~ted
to fomm a fine cell suspens;on. Immobilization of these cells in B5~.2 medium was pelfu,,,,ed in
a thin layer of phytagel (Toonen et al. 1994). After one week of further culture 24-D was
removed by washing the plates with B5~ medium. This allowed embryos to develop beyond the
globular stage. Recording the dovelou",ent of the immobilized cells was pe,~t,""ecl with a
procedure modified from the previously described by Toonen et al. (1994). The main change
involved a new MicroScan program for automatic 3-axis movement to scan all cells in the
phytagel (Toonen et al. 1996).
Nucleic acid isol~iG,- and ~
RNA was isolated from cultured cells and plant tissues as described by De Vries et al. (1988b).
Poly(A)~-RNA was obtained by pu,ification by oligo (dT) cellulose (Biolabs). For RNA gel blot
analysis samples of 10 mg total RNA were elecl,uphGresed on fo,lllall. ~8 gel, and l,~"a~e"~d to
nytran-plus membranes. For RNA spot-blot analysis 5 mg of total RNA was denatured and
spotted onto nytran-plus filters using a hybridot manifold (BRL).
Genomic DNA was isolated according to Sterk et al. (1991). Samples of 10 mg genomic DNA
were digested with d~ren~ ~sl,i~;tion enzymes and separated on agarose gel and l,~naIt u~d
to nytran-plus ",en,~,dne (Schleicher & Schuell). Hybri-Ji~tion of RNA blots took place at 42~C
in hybr,di~tion buffer containing 50% formamide, 6xSSC, 5xDel-l-al-Jl 0.5% SDS and 0.1
mglml salm sperrn DNA. HyL.r,Ji~d~ion of DNA blots was pe,Iol",ed as previously desc,ibed
(Sterk et al. 1991). F~"~wi.lg hybriJi~lion filters were washed under sl,i"gerit conditions (3x20
min in 0.1% SSC 1% SDS at 65~C). Filters were e~ll-osed to Kodak X~mat AR film. The
integrity and the amount of RNA on the blots was co"~i""ed by hyb,iJi~a~.on with an 18S
,il,oso",al RNA probe. Nucleotide sequence analysis was pe,k"",ed on an ABI 373A au~c",~tt,d
DNA se~uencer (Applied Biosystem).
Sc~ening ~ du~s
Two i,.dependehl cDNA libraries were constructed with equal amounts of poly~A)~-RNA from
total established cell cultures grown for six days in B5-2 medium sieved <125 mm cell cultures
grown for six days in B5~ medium and sieved ~30 mm cell cultures grown for six days in B5

medium. cDNA synthesis and cloning into the Uni-ZAPTM XR vector was performed according to
the manufacturers protocol (Stratagene).
D~ler~-ltial screening of the cDNA libraries was p~-fo",-ed essential.~r as clesc-il,6d by Scott et
al. (1991). RNA was isolated from either three embryogenic or three non-embryogenic cell
cultures that were grown for seven days in B5-2 after sieving through 30 mm mesh. hrst strand
cDNA synthesis was pell~"lled on 4 mg total RNA using AMV reverse trans~;,i,ulase (Gibco
BRL). [32P}dATP labeled probes were pr~:pared using random prime labeling on first strand
cDNA. Pooled probes from embryogenic and non-embryogenic cell pop~ tions were hyl,ridi~ed
to two pairs of nitrocellulose filters each containing 1000 p'-ques from one cDNA library. After
washing for 3x20 min in 0.1% SSC, 1% SDS at 65~C hybriJi~ation was visu~ d by
autoradiography for two days on Kodak X-omatic film. Plaques that only showed signal with the
embryogenic transcript probe were purified by two further rounds of screening.
In order to identify cDNA clones which are e~,essed at low levels in the c30 mm sieved cell
pop~'otion, cold plaque screening was performed as described by Hodge et al. (1992). Plaques
from the diller~"lial screening that did not show any signal after seven days of autoradiography
were purified by two further rounds of screening. The resulting clones were used as probes for
characterization of the ex~,r~ssion pattern of the corresponding genes.
D~ lial Display RT-PCR
C:'~erential display of mRNA was pe,l~""ed esse,ltially as described by Liang and Pardee
(1992). cDNA synthesis took place by annealing 1 mg of total RNA in 10 ml buffer containing
200 mM KCI, 10 mM Tris-HCI (pH 8.3) and 1 mM EDTA with 100 ng of one ot the following
anchor pr""eia. (5'~ &C-3') (5'-11111111111~ 3') (5'-l l l l l l l l l l l~A-3').
Annealing took place by heating the mix for 3 min. at 83~C followed by in~ h~tion for 30 min at
42~C. Annealing was ~. ~ued by the aJdi~ion of 15 ml pre-wammed cDNA buffer containing 16
mM MgCI2, 24 mM Tris-HCI (pH 8.3), 8 mM DTT, 400 mM dNrP, and 4 Units AMV reverse
h~ns~ Jt~se (Gibco BRL). cDNA synthesis took place at 42~C for 90 min. hrst sband cDNA was

separdled on a 6% denaturing DNA sequencing gel. Gels were dried without fixation and bands
were visualized by 16 hours of autoradiography using Kodak X~matic film. Bands containing
dHferentially ex~r~ssed cDNA fragments of 150-450 nu~4Oticles were cut out of the gel and
DNA was extracted from the gel slices by electroelution onto DE~1 paper (VYhdtmdnn). After
washing of the paper in low salt buffer (100 mM LiC12 in 10 mM TE buffer), and elution of the
cDNA in high salt buffer (1 M LiCIz in 10 mM TE buffer with 20% ethanol) the cDNA was

Adult plant tissues from Daucus carota were obtained from S8G Seeds (En~huizen). Cont,~
pollination was performed by hand. Flower tissue RNA was obtained from three compete umbels
for each time-point and contained all flower organs including pollen grains. 2 mg of total RNA
from adult plant tissue or cell cultures was annealed at 42~C vnth 50 ng oligo (5'-
TCTTGGACCAGATMTTC-3') in 10 ml annealing buffer (250 mM KCI, 10 mM Tris-HCI pH 8.3,

Whole mount in situ hyL.i~ ;G~
Whole mount in situ hyl,rkli~ations were pe-lu""ecl essentially as previously described (Engler et
al. 1994). Cell cultures and somatic embryos were immobilized on poly-L-lysine coated glasses
during fixation to improve handling. Whole mount in situ hybridization on e~lar,t~ took place by
embedding hypocotyls from seven-days old planti -~ in 3% ~~eap'?que agarose (Duchefa) and
p,~cessi"g them in Cppendo,t tubes. Transverse as well as longitudinal sections were made
with a vibrotome (Biorad Microcut). Sections of 50-170 mm thick were inc~ Ih:~tRd in B5-2 medium
for a minimum of three days to induce fo""alion of emb~o-fomming cells. Optimal induction was
achieved with longitudinal hypocotyl se- lions with a thictcness of at least 90 mm. To obtain
proliferating non-embryogenic cell cultures hypocotyl se~;tions were e~l~osed to 2 4-D for only 1
day, and subsequently lldllslerl~d to B5-0 medium (Guzzo et al. 1994). Whole mount in situ
hytJ,i.li~alion on developing seeds was pello""ed by removing the chalazal end of the seeds to
allow easier probe penetration. After hy~,ridi~lion the env~ ~p;.,g layers of integuments and
endosperm were carefully removed to expose the dcv~ ~p:.,g embryos. In situ hyt.,idi~alion on
se~lions was performed as described previously (Sterk et al. 1991) except for the use of non-
radioactive probes.
All samples were fixed for 60 min. ir, PBS containing 70 mM EGTA 4% paraformaldehyde
0.25% glutaraldehyde 0.1% Tween 20 and 10% DMSO. Samples were then washed, treated
with proteinase K for 10 min again washed and fixed a second time. Hybridization solution
consiated of PBS co"~i"ii)g 0.1% Tween 20 330 mM NaCI 50 mg/ml heparin and 50%
deoni~ed fommamide. HyL,ridi~ation took place for 16 hours at 42~C using digoxigenin-labeled
sense or antisense ,il.oprubes (Boet"i"ger Mannheim). After washing the cells were treated with
RNaseA, and inc~h~ted with anti-digoxigenin-alkaline phG:"~ha~se cor, :g~te (Boet"i"yer
Mannheim) which had been pr~absG,L,ed with a plant protein extract. Excess anffbody was
removed by washing followed by rinsing in staining buffer (100 mM Tris-HCI pH 9.~, 100 mM
NaCI 5 mM MgCI2 1 mM levd", s-'~) and the staining reaction was pe.lu,,,,ed for 16 hours in a

A fusion protein cons-ati,lg of SERK and the glutathione S-t,dn~erdse gene product was
sy"ll,esi~ed by a three hours induction of l-~h~u""ed E.coli with 2 mM IPTG. Fusion protein
was isolated and purified as des.;,il,ed previously (Hom and Walker 1994). Purified fusion
protein was coupled to glutathione agarose beads (Sigma) and inc~ ~h~tsd for 20 min. at 20~C in
a volume of 10 ml buffer 50 mM Hepes (pH 7.6), 10 mM MgCI2, 10 mM MnCI2, 1 mM DTT, 1
mCi [y 32p] (3 000 CUmmol) . Excess label was removed by washing the fusion
protein/glutahone agarose beads three times for 5 min. in 50 mM Tris-HCI (pH 7.3) 10 mM
MgCI2 at 4~C. Protein was removed from the beads by cooking in SDS-PAGE loading buffer.
Equal amounts of protein were sepa,~lecl by SDS-PAGE and protein autophos~horylation was
vicl 1- ' ~ed by autoradiography.
SERK fusion proteins produced with the Baculovirus exl,ression system.
Further fusion pro~3ins containing the intracellular part of the l~ o(ls carota SERK protein
(1.0 kB Hindlll / Sspl fragment of the carrot SERK cDNA clone 31-50) were made using the
baculorvirus vector pAcHLT.
In VitrD phosphorylation studies with this purified protein showed that most if not all of the
autophosphorylation of this SERK fusion protein was at threonine residues (Figure 6)
Construction of viral l,dnsIer vectors
The pAcHLT-B and pAcHLT-C baculovirus transfer vectors were used for the cioning of two
cDNA fragments of the carrot SERK gene. The Sspl 1.41 kB fragment of carrot DcSERK
cDNA was cloned into the Smal site of pAcHLT-B and the Sspl / Pvull 1.07 kB fragment of
carrot DcSERK cDNA was cloned into the Smal site of pAcHLT-C. The first construct
conldins the complete C-terminal part of the DcSERK protein and from the putative
extPcell~ region the proline-rich region and three of the lecuine-rich repeats. The second
construct conldins only the putative intracellular region of the DcSERK gene product.
Nucleotide sequence analysis was pe,(ur",ed in order to confirm the presence and the
G,ienl~liGn of the DcSERK cDNA within the vector.
T.dhs~u,,,,ation of insect cells
The resulting l,dnsfer vectors were used to l-ansfect (lipofect) insect cell culture Sf21 from
S~odoplerd frugiperda in co",~;.)dlion with lineari~ed AcMNPV b~cu'G-inus DNA.

was added to 5 microgram of pAcHLT I SERK vector construct in 25 ")ic,~,liler of water.
Fifteen mi~;r.l;ts~ of Li~ofeclin (BRL) was mixed with 10 microliter of water, after which the
DNA solution was added. After mixing 200 mtcroliter of Hink's medium was added to the mix
and the solution was l,dr,~le"~ecl to the cell monolayer, from which the medium was
removed. After one hour, 500 microliter of Hink's medium was added and the cells were
incubated for anotehr 3 hours. Finally, 1 ml of Hink's medium with 20% foetal bovine serum
(FBS) was added and the cells were incuh~ted for 4 days. After transfection, the viral
infection could be identified by the reduced growth of cells, the swollen shape and the
enlarged nucleus. After four days, infected cells were harvested and the medium containing
infectious budded virus was collected and used for plaque assays and a",plificalion of
recombinant virus stocks.
Iss'-tion of single recombinant viruses
Single recombinant virus plaques were isol~ted from monolayers of cells infected with a
titration range of the primairy virus stock. Infections was performed in 35 mm petridishes
with monolayers of cells. Virus stocks were diluted in 600 microiieter of Graces medium and
added to the cell monolayer, followed by a 90 minutes incubation period at in Graces
medium with 20% FBS. Afterwards, 3% Sea Plaque agarose was autoclaved, mixed with an
equal amount of 2x Graces medium with 20% FBS and from the resulting agarose overlay
solution 2 ml. was spread over the cell monolayers after removal of the viral inoculum. After
4 days of incubation single plaques could be vis~ 7ed and purified for further analysis.

After dehr",i,ling the titer of purified recor"~ ar,l viruses, monolayers of Sf21 cells in 7~
cm2 flasks were infection with a multiplicity of infection (MOI) of 10. Incubation of cells with
the vinus inoculum was performed for 90 min. after which 8 ml. of Hink's medium with
10%FBS was added. After 3 days of inc~h~tion, cells were harvested and washed twice

The Iysate was cleared by centrifugation at 10.000 9 for 30 min and the supernatant was
bat~ ise inc~h~ted in TALON resin (with high affinity for the 6xHlS tag of the reco",binanl
fusion protein). Binding was pe,~ur,,,ed by gentle ~git~tion for 20 min. at room temp. The
rssin was washed three times with Iysis buffer, followed by an elution step with Iysis buffer
with 200 mM imidazole. Purified fusion protein was ~el eeted and purifty and integrity was
tested by SDS-PAGE.
Autophosphorylation assays
Protein kinase activity was deternined by incubating 1 microgram of purified fusion protein
for 30 min. at room temp. in a buffer containing 10 mM MgCI2 10 mM MnCI2 1 mM DTT
and 10 ~M [gamma-32]ATP (105 pm/pmol ATP). The autophosphorylated fusion proteinwas purified after SDS-PAGE from the gel in a buffer containing 50 mM NH4CO3 0.1%
SDS, 0.25% beta-mercaptoethanol. Protein was prec;~ te~l with 20 ~g/ml BSA and 20%
(w/v) solid l,ichloruacetic acid. The precipitate was collected after centrifugation hydrolysed
in 50 1~l 6N HCI for 1 hour at 120 degrees Celcius. HCI was s~hsequently removed by
Iyophilization and the pellet was resuspended in a buffer consiti"g of 2.2% formic acid and
7.8% acetic acid. Hydrolysed protein was loaded onto cellulose thin layer cl"o",atography
plates together with control amino acid samples (phosphoserine, phosphotl"~onine,
phosphotyrosine). Chromatography was performed in a buffer containing pr.Fionic acid: 1M
ammonium hydroxide: iso~rupyl alcohol (90:35:35 v/v/v). After separation and drying of the
plates the separated amino-acids were visualized by spraying with 0.25% ninhydrin in
aceton followed by heating for 5 min. at 65 degrees Celcius. Plates were afterwards
exrosed to Phospho Imager casettes in order to detect the ~.hos~ ho-labeled aminoacids.

INTRODUCTION OF THE SERK GENE INTO PLANTA AND THE PRODUCTION OF
APOMICTICSEED
Carrot transformation with a SERK Dromoter fraament/lucileldse aene fusion
The binary vector pMT500 is based on the pBlNt9 vector (Bevan, 1984) and c~ ins the
firefly luciferase gene doJ~r"al,~am of a polylinker containing 5 unique resl.i~:tion sites was
created by uni-di,e.;tional ligation of the firefiy luciferase coding region folloNed by the
polyadenylation sequence from the pea r~cS::E9 gene in the Hindlll-Xbal site of the binary
vector pMOG800 (kindly provided by Mogen N.V. Leiden The Netherlands). The binary
vector pMOG800 is based upon pBlN19 (Bevan 1984) but while in pBlN19 the polylinker is
flanked by the left border and the neomycin phosphol,dr,~lerase (NPT ll) expression
casselle the poiylinker in pMOG800 is flanked by the right border and the NPT llexpression cassette. From a geno,l,ic lambda clone ll~nsc,iplion regulating sequences
from the carrot SERK gene were isolated by digestion with Hindlll and Dral (SEQ ID No. 1),
and cloned into the Hindlll / Smal sites of pBluescript SK+. From the resulting vector a Kpnl
/ Sstl fragment containing the SEF~K genomic DNA was isol~ted and cloned into the Kpnl /
Sstl sites of the binary vector pMT500. The resulting DNA construct, pMT531 contained the
2200 bp genomic SERK DNA fragment as ~ro",ott:r sequence the luciferase gene as vital
reporter and the E9 t~ansc~ tion terminator sequence.
The binary vector pMT531 was transformed by elecl,oporation into Agrobacterium
tumefaciences strains MOG101 and MOG301 (for transformation into carrot cells) and into
Agrobacterium tumefaciences strain C58C1 (for transformation into Arab~dipsis thaliana
plants). Transfonned colonies were selected on LB plates wlth 100mg/l kanamycin.
T,dn~l."",ation of carrot cells
The firefly luciferase coding sequence under control of the geno",ic carrot Hindlll / Dral
2200 bp DNA fragment was introduced into carrot cells by Asi,ubal,teri~lm tumefaciens
mer~iated l,dr,s~ur,,,~lion of hypocotyl segments. T,ansfo""ation of nau~us carota cv.
'Amsterdamse bak' was performed by slicing one week old dark grown seedlings into
segments of 10 to 20 mm. Sey-"ents were inc~h~ted for 20 minutes in a freshly pr~pared
10 fold diluted overnight culture of Agrobacterium.. The segments were dried andtldllsIer,~d to a modified Gamborgs B5 medium (P1 medium; S&G seeds Enkhuizen, The
Netherlands) su~p'e "ented with 2 IJM 2 4-D (P1-2) and solidified with agar (Difco, Detroit
Mi USA ). After two days of culture in the dark at 25 + 0.5 _C seg",snl:, were l,tlnsle,.-~d to

sGtidified P1-2 medium supplemented with kanamycin (100 mg ~ ), carbenicillin (500 mg-l~
1; Duchefa) and vancomycin (100 mg-1~1; Duchefa). Atter three weeks segments were
transferred to fresh plates and transfommed calli were selected after an additional three
weeks. Transformed calli were grown on P1-2 plates with antibiotics for 3 weeks at a 16
hour light/8 hour darkness regime. Trdnalull,led embryogenic suspension cultures were
initiated as described by transferring 0.2 g callus to 10 ml liquid P1-2 medium
supplemented with 200 mg-l~1 kanamycin, 250 mg-l~1 carbenicillin and 50 mg-l~1
\,ai1cG",ycin. During the first weeks 1 to 3 volumes of fresh medium were added to the
culture at weekly intervals. After 5 to 7 weeks cultures were s~ Ihcl ~tured to a packed cell
volume of 2 ml per 50 ml medium every two weeks and incuh~t~d at a 16 hour light / 8 hour
darkness regime at 25 + 0.5 ~C.
One week after transfer to kanamycin selection medium, hypocotyl segments were sprayed
with luciferin to test whether luciferase expression could be detecte~l in transformed callus
shortly after tranafor",ation. A large number ot hypocotyl segments sholled luciferase
activity at the cut edges, but did not develop calli. Instead, growth of bacteria occurred,
su~ge~l;ng that the luciferase activity was of bacterial origin. Six to ten weeks after
l,ansfor",ation, calli were obtained that showed luciferase activity in variable amounts, while
no bacterial growth could be observed anymore. After 12 weeks, calli measuring 5 to 10
mm in diameter were used to start suspensi~n cultures. At this time no bacterialconta",i"ation was observed. A control transformation experiment in which luciferase
ex~.ression under influence of the CaMV 35S promoter was observed in single cells and cell
clusters in the suspension culture del"onbl,dli"g that the luciferase protein is active in
Daucus cat~ta suspension cultured cells.
Cell immobilisation
Onc weelc old high-density (1 o6 107 cells-ml~1 ) suspension cultures were sieved through
nylon sieves with successive 300, 125, 50 and 30 ,um pore sizes (Monodur-PES; Versei~ag
Techfab, Walbeck, Germany). Single cells and cell clusters pa55;.~9 the last sieve are
designated as ~ 30 ~m popu'stiQns. Control expe,i",enla with utltlallafolllled cells were

medium. Size fraL:~ionatetJ cell popu~tiQns smaller then 30 llm were immobi'ised in phytagel
(P81g6; Sigma, St Louis, Mo, USA) in petripemm dishes (Heraeus, Hanau, Germany). The
bottom layer cor,sisled of 1 ml P1-0 medium with 5 mM Ca 2+ and 0.2 % phytagel. Two

hundred thousand cells (~ 30 IJm and c 50 ,um populations) in B5-0 medium without Ca 2+
supplemented with 0.1 % phytagel were poured on top of the bottom layer. For this layer B5
was applied since, at room temperature, phytagel solidified in P1 medium without Ca 2+.
After 2 hours of solidification an additional P1-0 layer with 0.2 % phytagel was poured onto
the cell layer preventing the B5 layer to move. To prevent dehydration of the phytagel layers
and to supply luciferin to the cells, 0.5 ml P1-0 medium containing 0.05 I~M luciferin
(Promega, Madison, Wi, USA) was added after solid;lication. The final luciferin
concentration in the culture was 0.02 ~M. Luciferin detection on single cells was determined
with a CCD camera for a period of 5 times one hour (Schmidt et al. (1997) Development
124:2049-2062). After 7 days of culture, luciferin was removed from the cultures by
extensive washing with P1-0 medium.

Agrobacterium strain C58C1 containing the l-anslur,,,ation plasmid was grown on a LB
plate with 50 mg/l kanamycin, 50 mg/l rifampicin and 25 mg/l gentamycin. A single colony
was used to inoculate 500 ml of LB medium containing 50 mg/l kanamycin, 50 mg/l
rifampicin and 25 mg/l gentamycin. The cultures were grown O/N at 28 degrees Celcius and
the resulting log phase culture (OD600 0.8) was centrifuged to pellet the cells and
resuspended in 150 ml of infiltration medium (0.5x MS medium (pH 5.7) with 5% sucrose
and 10 1~l/l benzyla",inopurine). The i.,llGrescenses of 6 Arabidopsis plants are sub",eryed
in the infiltration suspension while he remaining parts of the plants (which are still potted)
are placed upside down on meshed wire to avoid contact with the i"lill,dtion suspension.

Introduction of plant expression vectors into Ar3h;~0psis thaliana plant cells
The above described vector constructs (pAtLTP1AtSERK p35SAtSERK pAtDMC1AtSERK
pFBP2101AtSERK) have been electrotransformed into Agrobacterium tumifacienses strain
C58C1 as known in the art.
Wild type Ar7~1;L~ S thaliana WS plants are grown under standard long day conditions: 16
hours light and 8 hours dark.
The first emerging inflorescence is removed in order to increase the
number of influorescences. Five days later plants are ready for vacuum i"filtlation.
Agrobacterium strain C58C1 contai,-i.,y the tran~ur,,,alion plas",id (the pAtLTPtAtSERK
vector or the p35SAtSERK or the pAtDMC1 AtSERK vector or the pFBP2101 AtSERK
vector) is grown on a LB plate with 50 mg/l kanamycin, 50 mg/l rifampicin and 25 mg/l
ger,l~",ycin. A single colony is used to inocu'~t.s 500 ml of LB medium containing 50 mgA
kanamycin, 50 mg/l li~dlllp.Ci~l and 25 mg/l genta",ycin. The cultures are grown O/N at 28
degrees Celsius and the resulting log phase culture (OD600 0.8) is centrifuged to pellet the
cells and resusl)6"J6d in 150 ml of infiltration medium (0.5x MS medium (pH 5.7) with 5%
sucrose and 1 mg/l benzylaminopurine). The i,lflGresceoces of 6 Arabidopsis plants are
submerged in the infiltration suspension while the remaining parts ot the plants (which are
still potted) are placed upside down on meshed wire to avoid contact with the infilbdtion
sus~,ension.

Vacuum is applied to the whole set-up for 10 min. at 50 kPa. Plants are directly afterwards
placed under standard long day condilions. After completed seed setting the seeds are
surface sterilized by a 1% sodium hypochlo,ile soak then thoroughly ished with sterile
water and plated onto pet.idi~hes with 0.5xMS medium and 80 mg/l kanamycin in order to
select for l,dnalul,,,ed seeds. After 5 days germination under long day conditions (10.000
lux), the transforrned seedlings could be itJenlified by their green colour of their cotyledons
(the untransformed seedlings turn yellow) and are further grown in soil under long day
conditions. This vacuum infiltration method resulted in apprûxi,nately 0.1% trar,slor",ed
seeds.
E)~ression of SERK sequences in Ar~' 'cpsis thaliana plant cells
The inflorescences from transgenic and not transgenic Arabidopsis thaliana plants are
analysed by Whole mount ~n sifL hybridisation analysis with AtSERK cDNA as probe. The
i"llor~:scences in different stages of development are fixed for 60 min. in PBS containing 70
mM EGTA 4% pa,~fo""aldehyde, 0.25% glutaraldehyde 0.1% Tween 20, and 10% DMSO.
Samples are then washed treated with p,u~ei.,ase K for 10 min again v:~ ~hed and fixed a
second time. Hybridi~,ation solution cons;sled of PBS containing 0.1% Tween 20 330 mM NaCI
50 mg/ml heparin, and 50% deioni~ecl fommamide. HyL,ridi~alion took place for 16 hours at 42~C
using digoxigenin-labeled sense or antisense ,iboprubes (Boehnnger Mannheim). After washing,
the cells are treated with RNaseA and inc~lh~ted with anti-digoxigenin-alkaline phos~hatase
con ug~te (Boehringer Mannheim) which had been preabsorbed with a plant protein extract.
Excess antibody is removed by washing f~' ~w~ d by rinsing in staining buffer (100 mM Tris-HCI
pH 9.5, 100 mM NaCI, 5 mM MgCI2 1 mM le~,a",: e 'e) and the staining reaction is pe-Ium.ed for
16 hours in a buffer containing NBT and BCIP. Observations are performed using a Nikon
Optiphot m,~;,uscope equipped with Nomarski optics.
The l,dn:,lGr."ed plants show ectopic expression of SERK in the vicinity of the emb~yo sac.
