摘　　要：WRKY转录因子在植物的非生物胁迫中发挥了重要的调节作用,能够参与多种不同的信号途径,功能具有多样性。WRKY蛋白除具有高度保守的WRKYGQK基序外,通常还具有Cys2His2或Cys2His-Cys型锌指结构,它通过与靶基因启动子中的W-box[(T)TGACC(A/T)]特异结合调控其表达,从而响应植物的逆境胁迫及其它信号途径。为了帮助我们更全面地了解WRKY转录因子在植物中的作用,本文主要对近年来WRKY在植物非生物胁迫方面的研究进展进行了综述。The WRKY gene family has been suggested to play important roles in the regulation of transcripti＇onal reprogramming associated with plant stress responses. The WRKY transcription factors participate in the plant various kinds of defense responses. And a lot of experimental evidence shows that a single WRKY transcription factor might be involved in regulating several seemingly disparate processes. The WRKY protein contains a highly conserved WRKYGQK motif, with Cys2His2 or Cys2His-Cys zinc finger motif. WRKY transcription factors regulate the expression of target genes that contain the W-box elements in the promoter regions by specifically binding to （T） （T）TGAC （C/T） sequence. In order to makes us more comprehensive understanding of the WRKY transcription factor function in plants, this article reviews recent progress made in starting to reveal the role of WRKY transcription factors in plant abiotic stresses.
