摘　　要：WRKY转录因子家族是高等植物中最大的转录因子家族之一。WRKY转录因子名称来自其标志性的WRKY结构域,其与下游靶基因启动子区域的顺式作用元件W-box结合,激活或抑制下游基因表达。目前国内外学者已经在许多药用植物中开展了WRKY转录因子的研究,发现其家族成员广泛参与植物生长发育、衰老、次生代谢调控、生物胁迫、非生物胁迫等过程。本篇综述对WRKY转录因子的结构特征、调控方式和功能作用及其在药用植物中的研究进展进行了总结,讨论了WRKY转录因子在药用植物中存在的问题以及未来的应用前景,旨在为深入研究药用植物WRKY转录因子家族的调控机理,充分发挥其生物学功能提供研究思路。The WRKY transcription factor family is one of the largest families of transcription factors in higher plants.WRKY transcription factors are named from their signature WRKY domain,which could activate or repress the expression of downstream genes by binding to the cis-acting element W-box on the promoter region of target genes.WRKY transcription factors have been studied in many medicinal plants,and its family members have been found to be widely involved in plant growth and development,senescence,secondary metabolism regulation,biotic and abiotic stresses or other processes extensively at present.In this review,we summarize the structural characteristics,regulatory mode and functional role of WRKY transcription factors,as well as discuss the research progress,existing problems and future application prospects of WRKY transcription factors in medicinal plants,aiming to provide research ideas for the in-depth study of the regulatory mechanisms and biological functions played by the WRKY transcription factor family in medicinal plants.
