Abstract：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.
