Type-A response regulatorsRR)是细胞分裂素信号转导的末端组分,仅具有REC接收域,不仅影响植物生长发育,还响应非生物胁迫。本文中详细梳理了近年来草本和木本植物type-A RR鉴定、进化关系、表达模式、功能特征等研究进展,总结了潜在的调控网络,以期为深入理解type-A RR负调节细胞分裂素信号的机制提供参考。

Type-A response regulatorsRRs)are the terminal components of cytokinin signal transduction pathway merely possessing the REC receiving domain.Type-A RRs not only involve in regulating plant growth and development,but also regulating response to abiotic stresses.In this paper,the different aspects of recent studies on gene identification,gene evolutionary relationship,gene expression,and functional characteristics of type-A RRs in herbaceous and woody plants have been reviewed.In addition,the potential regulatory network of type-A RR genes were summarized.This review provided useful information for better understanding the mechanisms by which type-A RRs negatively regulate cytokinin signaling.
