摘　　要：WRKY因其特殊的七肽保守序列WRKYGOK而得名,是植物中最大的转录因子(transcription factors, TFs)家族之一,广泛参与植物对生物、非生物和激素胁迫的响应。WRKY TFs主要通过特异性结合靶基因启动子的顺式作用元件(T)TGAC(C/T)(W-box)来调控靶基因的表达和参与到植物响应不同生物、非生物和激素的信号通路中以及与多种蛋白发生相互作用来实现其在不同信号转导途径中的功能。本文针对WRKY TFs的结构、分类、起源与进化及其在响应生物、非生物胁迫和激素信号中的功能和调控机制进行了阐述,目的是系统总结植物WRKY TFs的研究进展,为相关研究者深入了解WRKY TFs及其介导植物抗逆性提高的分子机制,为作物遗传改良,提供有益参考。WRKY named for its special heptapeptide conserved sequence WRKYGOK, is one of the largest families of plant-specific transcription factors(TFs). It is widely involved in the response of plants to biotic,abiotic and hormonal stresses. WRKY TFs mainly regulate the expression of target genes by specifically binding cis-acting elements(T)TGAC(C/T)(W-box) of the promoters of target genes, participate in plant signaling pathways in response to different biotic, abiotic and hormonal stresses, and interact with multiple proteins to achieve their functions in different signal transduction pathways. In this review, the structure,classification, origin and evolution of WRKY TFs and its function and regulatory mechanisms in response to biotic, abiotic and hormonal signal were described, which aims to systematically summarize research progress of WRKY TFs in plants. This review provides relevant researchers with an in-depth understanding of WRKY TFs and the molecular mechanism how it mediates to improve plant resistance, and also provides a useful reference for crop genetic improvement.
