Annotated Information

Function

Please input function information here. OSH15 cDNA 1566 bp, contains five exons and encoding a 355 amino acid composition of protein products.Mutant d6 - tankanshirasasa and d6-1 is due to part of the loss of the exon 4 and exon 5  ;Mutant d6 - ID6 is because of missing part of a total of about 700 bp of exon 1 and 5 'UTR and 1 part of introns .（Sato et al., 1999）

OSH15 encoding a protein containing homologous heterotypic structure domain.OSH15 might be responsible for decide the position of elongation internode of grassroots outside cells, control of small vascular bundle sheath, sclerenchyma and the growth of epidermal cells;OSH15 possible in two ways to control the morphology and differentiation of internodes cell: one is the OSH15 may adjust the intercalary meristem cell division rate of intercalary meristem and maintain the quarter life to influence the internode elongation;The second is OSH15 may as the development of dermal cells develop into thick wall switch (Sato et al., 1999)

KNOX homologous genes alien to maintaining culture cell in undifferentiated state is enough, on the stage of meristematic cells pending the formation and maintaining of has an important role.Reference OSH1 (Ito et al., 2001)

OSH a gene expression can induce transgenic rice leaf sheath of ectopic bud, their ectopic expression interfere with leaf development and to promote leaf is in a state of undifferentiated, reference OsH43 (Sentoku et al., 2000)

Expression

Please input expression information here. To identify model of crop rice involves genes during embryogenesis, the Japanese scholar built specific cDNA library at the stage of embryonic development after organ differentiation in the former .The author focuses on KNOX (corn knotted1 similar mutant) homologous alien genes which may function in the regulation of rice embryogenesis. In early zygote embryo library，researchers identified three types of KNOX genes, two of them are Oskn2 and OsKn3, while OsH1 OsKN1 was previously reported.In situ hybridization showed that in the early embryonic development, three KNOX genes in the shoot apex meristem SAM organogenesis of regional expression.Show three KNOX genes are involved in regulating the formation of SAM.But before someone reports OsH1 involved in maintaining function of SAM.Oskn3 may participate in the shape of organs positioning mode, its expression can be divided with SMA form the boundary of different embryonic organs.Oskn2 expression patterns showed that the gene in shield and the development of the ectoderm.Oskn2 and OsKn3 expressed in tobacco further support the KNOX is involved in cell fate determination.Just like Knotted1 OsH1 ectopic expression of Oskn3 transformant in nutrition growth phase has the most significant phenotypic effects, OsKn2 transformant at vegetative stage has a relatively small change but flowers form is more serious.KNOX transgenic tobacco produce similar phenotypes, suggesting that the function of the gene product overlap each other, but different target genes or the special factor to determine the cell type the KNOX genes more precise behavior (Postma - Haarsma, et al., 1999). Homologous alien genes in many eukaryotes have an important regulatory role in the plant and the decision of the body， including to the establishment of a cell or area. Japanese scholars separated and identified a piece of code is KNOTTED homologous protein cDNA sequence of alien box, named OsH15.In OsH15 cDNA of expression in the tomato, the tomato development certain parts of the disorder, phenotypic change obviously, so think OsH15 involved in plant growth.OSH15 do through the entire plant life cycle of the in situ hybridization and the analysis and comparison with OSH1, the authors found that in the early stages of embryogenesis, two genes into SAM in the future development at the same site expression mode, while in the later performance, OSH1 can increased expression in the SAM, and OSH15 expressed in SAM would stop, but still can be in some boundary ring of embryonic organ models that can be observed.This expression pattern in nutrition or reproductive stem end, or plant HuaFen in similar groups.In situ hybridization showed that OSH1 play an important role in stems form , the early embryogenesis, and taking part in the shoot apex meristem of the surrounding organs (Sato et al., 1998)
