摘要
PRRs家族基因作为生物钟核心振荡器的主要组分,在植物光周期控制开花途径中起抑制作用,并通过调控ABA等方式影响植物抗逆性,对植物生物量的积累有重要影响,在植物生长发育过程中起重要作用。综述了PRRs家族基因的结构特征、光周期调控作用模型及其对逆境的响应方式,将为进一步研究PRRs家族基因的功能和培育优质广适性作物品种提供理论参考。
The PRRs family gene,which serves as a major component of the core clock of the circadian clock,plays important role in inhibiting the plant flowering,and manipulating ABA-dependent stress resistance and the accumulation of plant biomass.This article reviews the structural characteristics of the PRRs family genes,the photoperiod regulation model and its responses under stress treatments,in order to provide a theoretical reference for further study of the function of PRRs family genes and the cultivation of high-quality and broad-adaptability crop varieties.
