SPECIFICATION
The IRE gene regulating the root-hair growth in Arabidopsis
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to a gene coding for a
protein that is involved in regulation of tip growth in plants,
and also to the promoter of the gene.
Prior Art
Unlike other cells, it is known that root hairs of plants
elongate in a particular manner called tip growth. Pollen tubes
of higher plants also perform tip growth. Tip growth is also
observed in those eukaryotic cells that hold cell walls in ferns,
mosses, algae, fungi and so forth. A number of mutants that
show abnormalities in the number or shape of root hairs have
been isolated from Arabidopsis. hy5, phyB, rhd2 and tipl are
known as mutants with abnormal root-hair lengths (Genes &
Development, Vol. 11, p. 2983-2995 (1997); Plant Cell, Vol. 5, p.
147-157 (1993); Plant Cell, Vol. 2, p. 235-243 (1990); Plant
Physiology, Vol. 103, p. 979-985 (1993)). These mutants except
tipl show various phenotypes in addition to root-hair elongation,
suggesting that roles of these genes are not restricted just to
root hairs or to tip growth. It is therefore unclear how these
genes are involved in root-hair elongation. Since the tipl
mutant shows abnormalities in elongation both of root hairs and
1

CA 02301257 2000-03-24
pollen tubes, tipl is considered as a tip growth-impaired mutant.
The molecular function of this gene product has not yet been
revealed. As described above, those genes that specifically
function in regulation of the root-hair elongation or tip growth
have remained to be seen.
SUMMARY OF THE INVENTION
The present invention aims to isolate a novel gene
regulating tip growth such as root-hair elongation and to use
the gene for providing plants that show altered tip growth rates.
The present inventors have made great efforts to solve the
above mentioned problems and isolated a short root-hair mutant
of Arabidopsis. They have cloned the gene responsible for the
phenotype. Furthermore, the cloned gene has been introduced
into plants and the effect of the gene has been confirmed. Thus,
the present invention has been completed.
The first aspect of the present invention relates to a
gene coding for a protein (a) or (b) mentioned below:
(a) a protein represented by the amino acid sequence as set
forth in SEQ ID NO.: 2; or
(b) a protein represented by an amino acid sequence having one
or more amino acids deleted from, substituted in, modified in or
added to the amino acid sequence as set forth in SEQ ID NO.: 2,
and having a tip growth regulating activity.
The second aspect of the present invention relates to a
DNA (a) or (b) as mentioned below:
(a) a DNA represented by the nucleotide sequence as set forth in
SEQ ID NO.: 3; or
2

CA 02301257 2000-03-24
(b) a DNA represented by a nucleotide sequence having one or
more nucleotides deleted from, substituted in or added to the
nucleotide sequence as set forth in SEQ ID NO.: 3, and having a
function as a promoter.
This specification includes part or all of the contents as
disclosed in the specification and/or drawings of Japanese
Patent Application No.82402/1999, which is a priority document
of the present application.

DESCRIPTION OF THE INVENTION
The present invention is hereinafter described in detail.
(1) First Invention (Structural Gene)
The first invention relates to a gene coding for a protein
(a) or (b) as mentioned below and encompasses the protein
encoded by the gene, mutant genes, organisms carrying these
3

CA 02301257 2000-03-24
genes:
(a) a protein represented by the amino acid sequence as set
forth in SEQ ID NO.: 2; or
(b) a protein represented by an amino acid sequence having one
or more amino acids deleted from, substituted for, modified in
or added to the amino acid sequence as set forth in SEQ ID NO.:
2, and having a tip growth regulating activity.
The term "one or more" used herein means the number of
amino acids which can be deleted or otherwise altered according
to the technology conventionally used at the time of filing the
present application such as the site-directed mutagnenesis.
Chemical modification of amino acid residues in a protein
is commonly carried out in the art: see, for example, Hirs,
C.H.W. and Timasheff, S.N., eds, (1977) Methods in Enzymology,
Vol. 47, p. 407-498, Academic Press, New York.
The gene coding for the amino acid sequence as set forth
in SET ID No.: 2 modifies the elongation of root hairs. This
is shown by the fact that the mutant impaired this gene displays
shorter root hairs. This effect is restricted in root hairs
because the mutant shows the normal elongation of root hair-
bearing cells. Thus we have named this gene IRE (Incomplete
Root-hair Elongation). No gene products that have a tip growth
specific function have not been found.
The IRE gene can be cloned according to the method of
Japanese Patent Application Laying Open No. 10-4978 as described
below.
First, genomic DNA of Arabidopsis is fragmented with an
appropriate restriction enzyme and the DNA fragments are ligated
4

CA 02301257 2000-03-24
into an appropriate vector for a genomic DNA library. This
library is amplified by transforming into a host microorganism.
The isolation of DNA may be carried out in a conventional method
using cesium chloride and ethidum bromide. The restriction
enzyme is not particularly limited and may include, for example,
Sau3AI. The vector is also not particularly limited and may
include, for example, a DASH II. The host microorganism may be
determined depending upon the vector used. For example, 1 Dash
II requires Escherichia coli XL-1 Blue MRA (P2).
Then, the above mentioned genomic DNA library is screened
for the genomic region of the IRE locus. A DNA fragment that is
adjacent to the T-DNA insertion in the ire mutant is used for
the probe. Since the ire gene is disrupted by the insertion in
the genome of the ire mutant, the adjacent region includes a
part of the IRE gene.
Positive clones selected by the above mentioned probe are
purified and the insert genomic DNA fragments are separated. A
genomic fragment is used for a probe to screen a cDNA library.
The cDNA library may be prepared according to a conventional
procedure. That is, the total RNA is isolated from plant
tissues and polyA+ RNA is purified using oligo(dT) resins. cDNA
is synthesized from the template polyA+ using a reverse
transcriptase. The synthesized cDNA is ligated into an
appropriate vector for a cDNA library. The library is amplified
by transforming into a host microorganism. Positive clones in
the cDNA library contain the IRE gene.
Capabilities of the hybridization between one DNA sequence
and others under stringent conditions may be determined, for

CA 02301257 2000-03-24
example, by the following method. First one DNA fragment is
blotted and immobilized onto a nylon membrane. Then, this
membrane is prehybridized by the solution containing 6X SSC,
O.O1M EDTA, 5X Denhardt's solution, 0.5% SDS, 100 ~g/ml
denatured salmon DNA at 65~C for one hour or more. A hybridized
solution is prepared by adding labeled DNA fragments or labeled
RNA transcripts of a DNA template in the prehybidization
solution. The prehybridized nylon membrane is hybridized in the
hybridization solution at 65 ~C for 3 to 16 hours. Thereafter,
it is washed in a solution containing 2X SSC and 0.1% SDS at 65
'C for 30 minutes. Then, it is further washed in 2X SSC, 0.1%
SDS solution at room temperature for 15 minutes. Further, it
washed in 0.1X SSC, 0.1% SDS solution at 65 ~C for 30 minutes.
Then, the signal on the membrane is detected by a suitable
method depending the labeling reagent.
In order to express genes of the first invention (the IRE
gene and modified genes) in a host, the genes may be inserted
into an appropriate expression vector and the recombinant vector
may be introduced into the host. Hosts are not particularly
limited. Plants are preferable but bacteria, yeast and animals
may be used. Species of plants used as the host are not
particularly limited but those species of soybean, rape, and
cotton may be preferable. Any expression vector may be used as
far as it contains both a promoter for the expression and a
marker gene that enable the handling the host. For example,
plant tissues preferably require vectors that carry the
cauliflower mosaic virus 35S promoter because of the wide
application of species. pBI121 vector (Clontech) is an example.
6

CA 02301257 2000-03-24
Methods to introduce a vector into the host are not particularly
limited and may be done depending upon the host organism. An
Agrobacterium-mediated method is preferable for introducing into
plant tissues although those methods using electroporation,
particle gun may also be applicable.
Since the gene of the first invention has a function to
modify tip growth such as elongation or root hairs, the
following utilities may be considered.
I) Applications using the tip-growth modifying activity in root
hairs.
Introducing the gene of the first invention into a plant
and expressing it therein can let the plant have root hairs with
different lengths which can provide drought resistance of the
plant. Bacteria in Rhizobium are parasites of leguminous plants
and they enable the plants nitrogen fixation. Those bacteria
are shown to infect only elongating root hairs. Thus plants
that have altered root-hair growth by using the gene can be
expected to improve the infectious efficiency of the bacteria.
II) Applications using the tip-growth modifying activity in
other than root hairs.
In higher plants, pollen tubes emerge from pollen grains
(male gametophytes) and elongate to female gametophytes while
the fertilization. It is expected that the manipulation of the
gene expression in pollen tubes may alter the fertilization
timing and efficiency. Namely, plants (male gametophytes) with
either promoting or retarding fertilization ability may be
created. Cotton fibers, which are the raw material of the
common fiber, cotton yarn, elongate with a kind of tip growth in
7

CA 02301257 2000-03-24
cotton fruits. Thus it is also expected to improve the quality
of cotton fiber.
(2) Second Invention (Promoter)
The second invention relates to a DNA (a) or (b) as
mentioned below and encompasses promoters, expression vectors,
organisms carrying these DNA sequences:
(a) a DNA represented by the base sequence as set forth in SEQ
ID NO.: 3; or
(b) a DNA represented by a base sequence having one or more
bases deleted from, substituted for or added to the base
sequence as set forth in SEQ ID NO.: 3, and having a function as
a promoter.
The term "one or more" used herein means the number of
nucleotide sequences which can be deleted or otherwise altered
according to the technology conventionally used at the time of
filing the present application such as the site-directed
mutagnenesis.
Since the DNA of the second invention exists in the
upstream region of the gene of the first invention, it may be
cloned according to the method of Japanese Patent Application
Laying Open No. 10-4978 as in the case of the gene of the first
invention.
The DNA of second invention function as a promoter in such
tip-growing tissues as root hairs and pollen grains (pollen
tubes). Recombinant genes that have any gene under this DNA
sequence can be expressed specifically in root hairs and/or
pollen grains. Thus useful biological functions depending upon
8

CA 02301257 2000-03-24
root hairs and/or pollen grains can be introduces.
EXAMPLES
The present inventions are illustrated in more detailed by
way of examples which in no way limit the scope of the present
invention.
Example 1: Production of transgenic plants for the isolation of
IRE
Transgenic plants for the isolation of IRE were created
according to the method of Example 1 of Japanese Patent
Application Laying Open No. 10-4978.
Seeds of Arabidopsis (variety: Wassilewskija [WS]) were
sterilized and sown on an agar medium. These seeds were
incubated at 4 'C in darkness for two to four days. This cold
treatment prompted breakage of seed dormancy and made the
germination uniform and enhanced the flowering timing.
Thereafter, seeds were germinated and grown under continuous
light at 22 ~C. The seed sterilization was carried out by using
a sterilization solution containing 10 ~ of Hitar (Kao) and
0.02 Triton-X 100. Seeds were mixed and vortexed in the
sterilization solution and allowed to stand at room temperature
for three to five minutes, and washed five times with sterilized
water. The agar medium contained 1/2 x Arabidopsis nutrient
salt solution and 1.5 ~ agar (Nakarai, special grade). lx
Arabidopsis nutrient salts solution was prepared by following:
985 ml distilled water or deionized water, 5 ml of 1M KN03, 2 ml
of 1M MgS04, 2 ml of 1M Ca(N03)2, 2.5 ml of 20mM Fe-EDTA, 1 ml of
trace element solution, 2.5 ml of K-P04 buffer (pH 5.5)]
9

CA 02301257 2000-03-24
(Hideaki Shiroishi et al., (1991), Gendai-Kagaku vo120, Plant
Biotechnology II, p. 38). The agar medium was autoclaved and
poured into petri dishes. This concentration of agar prevented
Arabidopsis roots from penetrating in the agar medium. It made
he observation of the root morphology easier. The light source
was built with two commonly used 40 W fluorescent lamps and one
Homolux fluorescent lamp (National). Plants were grown under
this light source at an about 30cm distance. The intensity of
the light was about 3000 lux.
Forty individuals of Arabidopsis at three weeks after the
seed sowing were inoculated with Agrobacterium. The inoculation
was carried out according to the modified in planta method
(Plant Journal, Vol. 5, p. 551-558 (1994)). In this method,
floral stems of plants were wounded in order to promote the
infection. Agrobacterium tumefaciens strain C58C1rif (Nucleic
Acids Research, Vol. 13, p. 6981-6998 (1985)) was obtained from
Velten, J. et al. and used. This strain carries pGV3850 HPT as
the intermediate Ti plasmid and between the right- and left-
borders, there is a hygromycin phosphotransferase gene driven by
the cauliflower mosaic virus 35S promoter on this vector that
acts as the selection marker for plants.
After the inoculation of Agrobacterium, those plants were
transplanted on soil of the 1:1 mixture of vermiculite and
perlite. After 1.5 to 2 months of transplantation, seeds (T1
seeds) were harvested. Those seeds were sterilized in a similar
manner to the above mentioned, and sown on a hygromycin
containing medium (1X Ganborg B5 mixed salts for culture medium,
1~ sucrose, 0.8~ agar, 10 mg/1 hygromycin B). Individuals

CA 02301257 2000-03-24
showing hygromycin resistance were selected and transplanted on
soil. The soil was mentioned above. After 1.5 to 2 months from
the transplantation, self-pollinated seeds (T2 seeds) were
harvested.
Example 2: Screening for root-morphology mutants
The screening was carried out according to Example 2 of
Japanese Patent Application Laying Open No. 10-4978. The T2
seeds obtained in Example 1 were sterilized, sown on an agar
medium and grown. The sterilization and the agar medium were as
above mentioned in Example 1. To facilitate morphological
observation of roots, the agar medium was placed in a
transparent plastic Petri dish (Eiken Kizai Kabushiki Kaisha, No.
2 square Petri dish, 14 cm x 10 cm).
The morphology of roots was observed through transmitted
light by means of a stereoscopic microscope OLYMPUS SZH-IDDL.
Morphologies of roots in about 300 lines of transgenic
Arabidopsis were examined and ire was isolated as an abnormal
root-hair length mutant. The length of root hairs was smaller
in the ire mutant (Fig. 1B) than in wild type (Fig. 1A).
However, the density of root hairs and the distance between root
hairs were identical, indicating that this mutation specifically
reduces the length of root hairs. A detailed analysis revealed
that the elongation of root hairs ceased earlier in the mutant
(Fig. 2B) than in wild type (Fig. 2A). This cessation in the
mutant resulted in 60 ~ of root-hair length of wild type.
Example 3: Genetic studies of the ire mutant
11

CA 02301257 2000-03-24
According to the method in Japanese Patent Application
Laying Open No. 10-4978, the ire mutant and wild type were
cross-pollinated. The phenotype (length of root hairs) of wild
type, ire and their F1 progeny was examined (Table 1).
Length of root hairs
t i ne (11m + SE)
Wild type 396 ~ 17
Ire 232 ~ 25
F1 progeny and wild type 452 ~ 32
As shown in Table 1, the Fl progeny showed root hairs of a
normal length like wild type, indicating that the ire mutation
is recessive. Among 711 individuals of selfed progeny of the F1
plants (F2 progeny), 165 individuals (23~) showed the short
root-hair phenotype, suggesting that this phenotype is caused by
a single recessive locus.
Example 4: Preparatory studies for the cloning of the IRE gene
The ire mutant was isolated as a T-DNA insertion line
carrying the selection marker. In order to examine if the
inserted T-DNA disrupted the IRE gene or not, selfed F3 seeds of
213 mutants in the F2 progeny were subjected to the linkage
analysis between the phenotype and the selection marker gene
(hygromycin resistance gene). All F3 progeny of every mutant
showed the hygromycin resistance on the selection medium (1x
12

CA 02301257 2000-03-24
Gamborg B5 mixed salts for medium, 1~ sucrose, 0.8~ agar, 10
mg/1 hygromycin B). Namely, each mutant in the F2 progeny
carried the T-DNA homozygously. Thus it was suggested that the
inserted T-DNA is closely linked with the IRE locus and probably
disrupts the gene. Therefore, genomic regions flanking the T-
DNA insertion should include the IRE gene.
Example 5: Cloning of the IRE gene
A genomic DNA fragment adjacent to the inserted T-DNA was
amplified and cloned by the TAIL-PCR method using the genome DNA of
the ire mutant as a template (Plant Journal, Vol.8, p.457-463
(1995)). The sequences used in the PCR are below: a first specific
primer 5'-CACATCATCTCATTGATGCTTGGT-3' (24mer); a second specific
primer 5'-CATAGATGCACTCGAAATCAGCC-3' (23mer); a third specific
primer 5'-GTGTTATTAAGTTGTCTAAGCGTC-3' (24mer); and arbitrary
primers 5'-(A/T)GTG(A/T/G/C)AG(A/T)A(A/T/G/C)CA(A/T/G/C)AGA-3'
(l6mer). A 0.7 kb PCR fragment was amplified using this set of
primers. The template genomic DNA was extracted according to
Example 4 of Japanese Patent Application Laying Open No. 10-4978.
An Arabidopsis genomic library was screened using the amplified 0.7
kb PCR fragment as a probe. Those genomic clones were isolated
that covered an about 10 kb region in which a sequence hybridized
by the PCR fragment was contained. This genomic region was divided
into several fragments and subcloned into pBluescript II KS+
(Stratagene) to determine the nucleotide sequence. The genomic
region underlined in Fig. 3 was used as a probe to screen a cDNA
library. A cDNA clone was isolated in this screening. The
screening of the genomic and cDNA libraries as well as the method
13

CA 02301257 2000-03-24
of determination of nucleotide sequences was as described in
Example 7 of Japanese Patent Application Laying Open No. 10-4978.
The isolated cDNA was only about 1 kb in length. In order to
isolate a full length cDNA, a PCR method was tried. cDNA that had
been synthesized for the cDNA library was used as a template and
several primer sets designed based on the genome sequence were used
for the PCR. Two PCR fragments were amplified when using the
following sets of primers and the PCR fragments and the isolated
cDNA were joined into a full length cDNA. One of the PCR fragments,
which is composed of 2.2 kb at the 5' region of the full length
cDNA, was amplified using following primers: f2384 f2384:
CAACCGCTTCTCTGTAATC and r4950: AGCCTTCCTATCCTGAATG. The other
fragment, which is composed of 1.2 kb at the 3' region of the full
length cDNA was amplified using following primers: f4897:
TCATGATTGAGCAGTTGGA and r6898: CCGAGCAAGTGTGTCC.
The nucleotide sequence of the full length cDNA was
determined. The full length except for polyA sequence consists
of 3842 by (SEQ ID NO.: 1) and the possible largest ORF (Open
Reading Frame) consists of 1168 amino acid residues (SEQ ID NO.:
2). A stop codon locates in front of the start codon in frame
of this ORF. The correspondence between the cDNA and the genome
of IRE gene is shown in Fig. 4. The IRE gene consists of 17
exons and the T-DNA was inserted into the promoter region in the
ire mutant. The wild-type genomic region as shown in Fig. 4 was
introduced into the ire mutant. A vector was reconstructed from
pBI121 (Clontech) by removing the b-Glucuronidase (hereinafter
referred to GUS) gene and replaced with the genomic region. pBI
121 carries a gene for kanamycin resistance and transformed

plants show the resistance against kanamycin. The construction
of vector and gene transfer into plants were carried out
according to the method of Example 8 of Japanese Patent
Application Laying Open No. 10-4978; however, the media for
selecting bacteria and plants were supplemented with 50 mg/1
kanamycin sulfate (Meiji Seika). As shown in Fig. 1C, the
transformed plant showed longer root hairs than the
untransformed plant (the ire mutant), indicating that this gene
has an ability to increase the length of root hairs.
Example 6: Tissue-specific activity of the promoter region of
the IRE gene
The DNA fragment as set forth in Fig. 6 (SEQ ID NO.: 3)
was obtained by digesting with restriction enzymes XhoI and
BamHI. This fragment was ligated into SalI-BamHI sites of
pBI101-2 vector (Clontech). This recombinant vector was used
for the transformation into wild-type plants (using the method
of Example 5 above). Restriction enzymes used were purchased
from Takara Shuzo. The GUS gene was to be expressed under the
control of the IRE gene promoter. The sequence as shown in Fig.
6 corresponds to the region spanning between XhoI and BamHI
sites in Fig. 4. The sequence of white letters in Fig. 6
corresponds to the first exon of the IRE gene where the start
codon ATG is enclosed with the rectangle. The sequences with
dotted underlines show exons of another gene adjacent to the IRE
gene. To observe the activity of the expressed GUS, the
transformants were treated with an X-Gluc solution (5.7 mM X-
Gluc (5-bromo-4-chloro-3-indolyl-~-glucuronide), 1.5 mM

CA 02301257 2000-03-24
K3Fe (CN) 6, 1 . 5 mM K4Fe (CN) 6, 0. 9~ Triton X-100) . Transformant
plants were soaked in the X-Gluc solution, subjected to a vacuum
treatment, and then incubated at 37 ~C overnight to develop the
color. Reagents used were purchased from Wako Pure Chemical.
The GUS activities were substantially shown in only the root and
pollen grains. As shown by arrows in Fig. 5B, the GUS activity
was found in pollen grains in the anther. Pollen grains are
germinated on a stigma and elongate pollen tubes. The GUS
activity was also found in elongating pollen tubes (Fig. 5C,
arrow). The foregoing indicates that the promoter of IRE gene
as set forth in SEQ ID NO.: 3 has activities in such tip-growing
cells as root hairs and pollen tubes.
The present inventions) provides) a structural gene
coding a protein that is involved in regulation of tip growth in
plants, and its promoter. Various plants with different
morphologies such as those showing prolonged root hairs, can be
created by utilizing the structural gene of the present
invention. Further, any gene may be expressed specifically in
tissues that are tip-growing by utilizing the promoter of the
present invention.
