Description

Rice Os01g0919200 gene-based microspore or pollen-specific expression promoter and its use {Microspore or pollen specific expression promoter from Oryza sativa Os01g0919200 gene and uses thereof}

The invention is rice (Oryza it relates to a rice-derived sopoja Os01g0919200 gene or pollen-specific expression promoter and use thereof, and more particularly sativa ) Os01g0919200 gene-expressing microorganism or pollen-specific expression promoter, a recombinant plant expression vector containing the promoter, and a step of transforming the vector into a plant, wherein the foreign gene is expressed in a microparticle or pollen-specific expression The present invention also relates to a method for producing the transgenic plant, a method for producing the transgenic plant, and a method for producing the transgenic plant.

The development of mature pollen from angiosperm spore forming cells requires highly complex and elaborate gene expression programs in haploid gametophytes and sporozoic tissues. In particular, it is known that the developmental process of male gametes, represented by plant pollen, involves a large number of genes (about 20,000 or more) that require elaborate expression control. In order to search genes expressing in microspore and pollen, genetic methods using mutants that can not normally produce male gametophytes or pollen were traditionally used, but now microarrays and next generation sequencing NGS, next generation sequencing) to produce a large amount of data in a short time.

The development process from the microspores to the mature pollen belongs to the germplasm of a plant that produces male spouses. It is an important biological process based on the existence of a relatively short cycle or seed plant, and the genes involved in this development are agricultural utilization The field of crop breeding using biotechnological methods is very large. In particular, a promoter that is expressed specifically in the microspores and pollen tissues can be used for cultivating a transformant that expresses a specific gene locally to the pollen tissue of a plant by producing a transgenic vector that binds to a foreign gene capable of inhibiting pollen development . Male sterile plants grown in this manner can be used directly as fertility seeds to produce one hybrid seed of major crops, including rice, and thus agricultural utilization is very high.

The heterozygosity of the crops can be explained by the fact that the F1 generation hybrid plants obtained through crossing between lines or cultivars of different genetic backgrounds in the cross-pollination or self-pollination plants are more vigorous than the parents used for crossing, And environmental stress, and it is widely used as a method of crop breeding. In addition, since hybridity is significantly weakened at the second generation of hybrids, most of the seeds currently marketed by seed companies are hybrid seeds of the F1 generation.

Since the reproductive structure producing plant seeds is so diverse and complex, it is not easy to produce hybrid seeds. In the case of rice, which is a typical self-fertilization crop, the one hybrid breeding technique has the potential to greatly increase the yield, but there are many breeding problems that have yet to be solved, such as the difficulty of seed production. In particular, Indica x Japonica first generation hybrids have a great effect of hybrids on nutritional growth, but they have not been put to practical use due to problems such as delayed heading and infertility. Currently, in China, the three systems of infertility, maintenance, and recovery are converted to two systems using environmentally sensitive male sterility systems, but due to various problems, they are going back to three systems.

To identify genes that are expressed only in the developing pollen of rice, the rice Os01g0919200 gene was selected through analysis of microarray data of development stages of rice anther and microspore. From the NCBI database (http://www.ncbi.nlm.nih.gov/), a nucleotide sequence of about 2 Kbp including the promoter of the gene and the 5'-UTR was obtained. To amplify the promoter fragment 1,779 bp, primers Os01g0919200P- (SEQ ID NO: 2) and Os01g0919200P-R (5'-GGATGCTTCGTGTTCTTGGGAGCTCCTT-3 '; SEQ ID NO: 3) (blue color in FIG. 1A) were prepared and the primers AttB1 and AttB2 (5'-AAAAAGCAGGCT-3 '; SEQ ID NO: 4, 5'-AGAAAGCTGGGT-3'; SEQ ID NO: 5) Genomic DNA was extracted from leaf tissues of the seedlings after 3 weeks of germination by using the CTAB method (Ronald PC and Chen DH, 1999, Plant Mol. Biol. Rep. 17: 53-57). The PCR reaction for the amplification of the promoter fragment proceeded in two steps. The first reaction was a reaction at 94 ° C for 5 minutes, followed by 10 cycles of reaction at 94 ° C for 30 seconds, 58 ° C for 30 seconds and 72 ° C for 2 minutes, Followed by reaction at 72 ° C for 5 minutes. The secondary reaction was carried out by using 10 μl of the first reaction product, adjusting the annealing temperature to 55 ° C., and performing the reaction 20 times. The other conditions were the same as the first reaction conditions, and the total amount was adjusted to 50 μl. The PCR reaction products were extracted from 1% agarose gel after electrophoresis and used for vector preparation.

Example  2. Plant expression vector production using the promoter of the pollen-specific expression gene derived from rice

GUS-GFP-tagged gene fusion vector was constructed in the following manner through a gateway cloning method (Invitrogen, USA) using the 1,779 bp promoter fragment as described above in order to test specific expression of rice flower pollen. The amplified promoter region was firstly cloned into pGEM-T Easy vector (Promega, USA) and inserted into a gateway pDONR201 entry cloning vector (Invitrogen) containing two recombination sites (AttB1 and AttB2) for BR clonase reaction Secondary cloning. The pDONR201 plasmid DNA having the 1,779 bp promoter region was extracted and sequenced using a primer complementary to the base sequence of the promoter region and the pDONR201 vector region. The nucleotide sequence was analyzed using the BIOEDIT program, (Fig. 1A). Through the LR recombination reaction, the promoter region of 1,779 bp was finally cloned into the destination vector pKGWFS7 and named pSK814 (Fig. 1B). pKGWFS7 contains the GFP-GUS fused marker gene lacking the promoter region and also has the recombination sites AttB1 and AttB2 for the LR reaction. The finally completed vector pSK814 for plant expression was obtained from Agrobacterium tumefaciens), the freeze-thaw method (Freeze-thaw) in the strain LBA4404 (An G, 1987, Methods in Enzymology, 153: 292-293 was transformed by using a), was used for transformation of rice plants using tissue culture methods.

Example  4. Transgenic rice plants GUS  Gene expression analysis

More than 20 T0 generations of rice plants were obtained using the plant expression vector pSK814. As a result of the PCR amplification using a primer for amplifying a part of the inserted T-DNA, 1 copy or more T- DNA was inserted. Each tissue of the plant was treated with 1 mM X-glu (5-bromo-4-chloro-3-indolyl-β-glucuronide), 100 mM sodium phosphate (pH 7.0), 10 mM EDTA , 0.5 mM potassium ferricyanide, 0.5 mM potassium ferrocyanide, and 0.1% Triton X-100 for 12 hours at 37 ° C and then reacted with 100% ethanol Chlorophyll was removed. As a result of GUS-tagged gene analysis, strong GUS expression was observed only in the microspheres and mature pollen tissues of T0 generation transformants (Fig. 2). The expression of the GUS-tagged gene begins at a two-cell stage where the nutrient and germ cells divide and is divided into three cellular stages in which the germ cells divide and a mature pollen stage consisting of one feeding cell and two sperm cells And the activity gradually increased (Fig. 2). RNAs of each rice tissue ( medicament , lobe, stem and root tissue) were extracted and the expression pattern of the Os01g0919200 gene derived from the promoter used in the present invention was examined. (5'-ATCGAGGCCAACGTCGGCGTCAC-3 '; SEQ ID NO: 6) and Os01g0919200-R primer (5'-GACGCCAGCACCAACCTTCGCAC-3) for RT-PCR analysis using the protein translation partial nucleotide sequence of the rice Os01g0919200 gene, Os01g0919200-F primer 3 '; SEQ ID NO: 7) was prepared and analyzed (the primer position in the gene is shown in red in FIG. 1A). As a result of the analysis, Os01g0919200 gene was specifically expressed only in the diseased tissues including the developing microsomes , and no expression was observed in the leaves, stem and root tissues grown at 2 weeks, 3 weeks and 4 weeks (FIG. 3A). In addition, leaf, stem and root tissues were collected and the expression of GUS-tagged gene was analyzed. As a result, it was confirmed that the GUS-tagged gene was not expressed in the above tissues (FIG. 3B). Therefore, the promoter used in the plant expression vector pSK814 was found to induce a specific expression only in the rice micropowder / flower pollen developing mature pollen from the two cellular epidermis of rice.

It was confirmed that these expression characteristics were similar to the rice microarray data used for selecting the pollen-specific promoter (Fig. 4). Analyzed microarray data includes developmental and pollen array results in both Indica and Japonica varieties. Sixteen surgical arrays and six pollen arrays were used for the Indica varieties, and 27 surgical arrays and 15 pollen arrays for the Japonica varieties. From the above results, it was confirmed that the rice strain Os01g0919200 used in the present invention was specifically expressed only in the rice sprout and flowerpot, which are commonly developed from the microspores to the mature pollen, in both rice varieties.

Example  5. Transgenic Arabidopsis thaliana plants GUS  Gene expression analysis

Twenty or more T1 generation Arabidopsis thaliana transformants were obtained using the plant expression vector pSK814. As a result of PCR amplification using a primer that amplifies a part of the inserted T-DNA, a T -DNA was inserted. The tissues of each T1 generation transgenic plant were stained by the same method as the method for staining the rice transformants, and the expression pattern of GUS-labeled gene was examined by each tissue and developmental stage. As a result of analysis of the expression of the GUS gene by collecting buds containing all of the flowering flowers from the young glume, the activity of the GUS enzyme was specifically observed only in the drug tissues containing the microparticles and pollen (FIG. 5A ). In order to investigate the expression patterns of GUS - tagged genes in developmental stage of microspores, the microspheres collected by size were dissected and classified into 1 cell, 2 cell and 3 cell sporulation and mature pollen by DAPI staining. The Arabidopsis thaliana transformant showed the highest level of GUS enzyme activity in the three cellular stages and the highest level in the mature pollen stage as the GUS gene was expressed in the two cell stage, (Fig. 5B). RNA was extracted from Arabidopsis thaliana (flowering flowers, pre-flowering buds, leaves, stems, roots and seedling tissues) and the expression of GUS gene introduced into Arabidopsis thaliana was examined. GUS-F primer (5'-CGTCCTGTAGAAACCCCAACCC-3 '; SEQ ID NO: 8) and GUS-R primer (5'-GCATTACGCTGCGATGGATTCCG-3') for the RT-PCR analysis using the GUS gene sequence, 9) were constructed and analyzed. As a result, it was confirmed that the GUS gene was strongly expressed in flowering buds containing mature pollen and pre-flowering buds, and not expressed in other tissues (FIG. 5C). The results showed that the promoter used in the plant expression vector pSK814 induces the expression specifically in the Arabidopsis vesicles and the pollen of the Arabidopsis developing in mature pollen at the two cellular epidermal stage.
