Abstract:

The rice response regulators (RR) family play important roles in plant growth and development, so it is important to explore the evolution and biological characteristics of the RR genes in rice. There were 22 RR genes in rice, including 15 A-type and 7 B-type genes. Analysis results showed that the rice RR proteins differed in their physicochemical properties, among which the B-type RRs were all hydrophilic proteins (GRAVY<0); homologous sequence analysis revealed that there were 5 paralogous gene pairs in the rice RR genes, namely, OsRR8 and OsRR15OsRR5 and OsRR11OsRR9 and OsRR10OsRR1 and OsRR2, and OsRR20 and OsRR18, which were predicted to have similar functions with known functional genes; the conserved Motif 1 and Motif 3 both belonged to the REC superfamily, which acted as response regulators to receive signals from the two-component phosphotransferase system, and they distributed among 22 OsRR proteins. The analysis of regulatory elements and expression pattern revealed that RR genes had potential ability in the regulating hormone signals transduction such as abscisic acid, salicylic acid, jasmonic acid, gibberellin, and growth hormone, and participated in plant defense against stress such as low temperature, drought, and light and anaerobic signals response, and also involved in the the regulation of different developmental processes of rice etc. functions. The bioinformatics analysis of rice RR gene family provided a theoretical basis for the in-depth study of their functions, and layed the foundation for further revealing the growth, development, and signal transduction mechanisms of plant.

摘要:

水稻反应调节因子 (response regulators,RR)家族在植物生长发育中扮演着重要角色,探究RR基因在水稻中的进化及生物学特征具有重要意义。水稻RR基因家族共有22个成员,包含15个A型和7个B型基因。分析发现,水稻RR蛋白的理化性质存在差异,其中B型均为亲水蛋白(GRAVY<0);水稻RR基因有5个旁系基因对,分别为OsRR8OsRR15OsRR5OsRR11OsRR9OsRR10OsRR1OsRR2OsRR20OsRR18,预测其与已知功能基因具有相似的功能;保守基序Motif 1与Motif 3均属于REC超级家族,作为响应调节器接收来自双组分磷酸转移系统中的信号传导,在22个OsRR蛋白中均有分布。调控元件与表达模式分析表明,RR基因具有调控脱落酸、水杨酸、茉莉酸、赤霉素与生长素等多种信号转导的潜能,参与植物防御低温、干旱等胁迫及光和厌氧等信号响应过程,同时也具有调控水稻不同组织生长发育的功能。通过对水稻RR基因进行生物信息学分析,为后续深入研究水稻RR家族成员的功能提供理论依据,也为进一步揭示植物生长发育及信号传导机制奠定了基础。
