摘　　要：WRKY是植物特有的转录因子。由于成员众多,WRKY转录因子形成植物中最大的家族之一。WRKY转录因子几乎参与了植物所有的生长发育调控过程。衰老是植物叶片生命周期的最后阶段,是叶片必经的生理过程。该过程主要由包括转录因子在内的多种因子调控。大量研究表明WRKY转录因子广泛地参与各种因素引起的叶片衰老调控。本文基于近年来发表的WRKY转录因子调控叶片衰老过程的相关研究,综述了WRKY转录因子在不同植物叶片衰老过程中所发挥的不同功能及信号转导途径,以期为进一步深入研究WRKY介导的叶片衰老调控机制提供理论支撑。WRKY is a kind of plant-specific transcription factor.Due to the large number of members,WRKY transcription factors belong to one of the largest family in plants.WRKY transcription factors are involved in almost all the growth and development regulation processes in plants.Senescence is the last stage of the life cycle of plant leaves and the necessary physiological process of leaves.This process is mainly regulated by a variety of factors including transcription factors.Lots of studies have shown that WRKY transcription factors are widely involved in the regulation of leaf senescence caused by various factors.Based on recent studies on the regulation of plant aging process by WRKY transcription factors,the different regulatory roles of WRKY transcription factors and the corresponding signal transduction pathways in leaf senescence were concluded in this review.It will provide theoretical support for further research on the regulatory mechanism of leaf senescence mediated by WRKY.
