• The study uncovers how WRKY TFs bind to DNA, revealing their precise role in regulating leaf senescence timing and progression. • WRKY TFs’ interactions with proteins shed light on their diverse functions during leaf senescence. • WRKY TFs fine-tune gene expression by controlling other TFs, crucial for nutrient redistribution during leaf senescence. • Investigating WRKY-mediated pathways unveils complex regulatory networks in leaf senescence. • Understanding WRKY TFs reveals how plants adapt to different environmental conditions, like extreme temperatures and nutrient deficiencies. Leaf senescence (LS), the final phase in leaf development, is an important and precisely regulated process crucial for plant well-being and the redistribution of nutrients. It is intricately controlled by various regulatory factors, including WRKY transcription factors (TFs). WRKY s are one of the most significant plant TF families, and several of them are differentially regulated and important during LS. Recent research has enhanced our understanding of the structural and functional characteristics of WRKY TFs, providing insights into their regulatory roles. This review aims to elucidate the genetic and molecular mechanisms underlying the intricate regulatory networks associated with LS by investigating the role of WRKY TFs. We seek to highlight the importance of WRKY -mediated signaling pathways in understanding LS, plant evolution, and response to varying environmental conditions. WRKY TFs exh...
