中文摘要：

综述了WRKY转录因子的发现、结构特点、表达特点以及WRKY转录因子在各种植物防卫反应中的调控作用，指出WRKY转录因子是一类参与多种胁迫反应的诱导型转录因子，其N-端具有WRKYGQK高度保守的氨基酸序列，能够与基因启动子中的（T）（T）TGAC（C/T）序列（W盒）发生特异性结合，从而调节基因的表达，参与植物的各种生长和发育过程。

英文摘要：

The structure features and expression regulation of WRKYs, and the regulatory roles of the transcription factors in the plant defense responses were emphasized in the paper. It indicated that WRKY transcription factors were a group of inducible transcription factors which were involved in a variety of stress responses. There was a conserved WRKYGQK amino acids sequence in N-terminal of the proteins. WRKY transcription factors regulate the expression of the target genes by binding to the W-box, a cis-element with （T）（T） TGAC（C/T） sequence in the genes promoter regions. Therefore, the WRKY transcription factors are involved in various physiological and biochemical responses in the plant.
