摘要： Plants are considered as sessile organisms that cannot avoid adverse environmental conditions and developed complex signaling networks composed of different pathways. WRKY transcription factors (TFs) are key regulators of various plant processes, including the responses to abiotic stresses. WRKY TFs are one of the largest family of transcriptional regulators found in plants. WRKY TFs act as molecular switches that modulate the expression of stress-responsive genes. Stress-induced WRKY TFs expression modulated by a complex transcriptional regulatory network that maintain the proper balance between growth, development, and stress responses. WRKY TFs typically interact with the W-box [TGACC(A/T)] of the target gene promoter to activate the expression of downstream genes. These TFs are associated in the regulation of different physiological processes. Overexpression of various WRKY genes faces the paradox of having various significant effects. These overexpression-associated undesirable phenotypes must be identified and removed for proper plant development. The present review summarized the recent development of various WRKY TFs during adverse environmental conditions as well as their role in plant growth, development and productivity for sustainable agriculture in near future.
