摘要
WRKY是植物中广泛存在的一类转录因子,其结构域中因含有保守的WRKYGQK七肽序列而得名,其成员能特异性地结合靶基因启动子区的W-box元件,调控植物的各项生理活动。WRKY转录因子在茶树中所行使的调控功能已成为研究热点,本研究主要从WRKY转录因子参与茶树的生物与非生物胁迫、生长发育和代谢等过程进行综述。有助于全面丰富WRKY转录因子在茶树中的研究基础,为深入研究WRKY在茶树抗逆、生长发育及茶叶品质形成等方面的分子调控机制及特异性茶树种质资源的开发和利用提供指导。
WRKY is one of the widely existing groups of transcription factors(TFs)in plants,named for the conserved WRKYGQK heptapeptide sequence in their structural domains,whose members specifically bind to the W-box elements in the promoter regions of target genes,and regulate various physiological activities in plants.The regulatory function exercised by WRKY TFs in tea plants have become a research hotspot.This study focuses on the review of WRKY TFs involved in biotic and abiotic stresses,growth and development,and metabolism of tea plant.This review contributes to comprehensive research of WRKY TFs in tea plant,and provides guidance for further studies on the molecular regulatory mechanisms of WRKYs in stress resistance,growth and tea quality formation in tea plant,as well as the development and utilization of specific tea plant germplasm resources.
