摘　　要：WRKY转录因子是植物最大的基因家族之一,参与植物的生物胁迫及非生物胁迫响应,调控相应基因的表达。ABA、SA及JA的信号转导受WRKY转录因子的调控,为了详细了解WRKY转录因子在各植物激素信号转导途径中的调控机制,本文针对WRKY转录因子对ABA信号转导途径的正负调控方式、WRKY转录因子对SA信号转导的3种调控方式(ICS途径、PAL途径及结合顺式作用元件)以及WRKY转录因子对JA信号转导的两种调控方式(调节JA生物合成基因和MYC2介导的JA信号通路)进行综述,并对深入研究WRKY转录因子在错综复杂的植物激素信号转导过程中的调控作用研究进行了展望。WRKY transcription factors are one of the largest gene family in plants.They are involved in plant response to biotic stress and abiotic stress and regulates the expression of corresponding genes.Some studies have shown that the signal transduction of ABA,SA,and JA were regulated by WRKY transcription factors.In order to gain a detailed understanding of the regulatory mechanisms of WRKY transcription factors in various plant hormone signal transduction pathways.This article focused on the positive and negative regulation of the ABA signal transduction pathway by WRKY transcription factors.The three regulatory modes of WRKY transcription factor on SA signal transduction-ICS pa thway,PAL pathway,and binding cis acting elements.A review was presented on the two regulatory mechanisms of WRKY transcription factors on JA signal transduction:regulating JA biosynthesis genes and MYC2 mediated JA signaling pathways,with a view provide reference for further research on the regulatory mechanisms of WRKY transcription factors in complex plant hormone signal transduction processes.
