叶片衰老是一个复杂的生物学过程，包括染色质重塑、转录、转录后、翻译和翻译后修饰。转录因子（TF）是叶片衰老的重要调节因子，NAC和WRKY家族是研究最多的。本文综述了这些家族在拟南芥和小麦、玉米、高粱、水稻等作物叶片衰老调控中的作用。此外，我们审查其他家庭，如ERF，bHLH，bZIP和MYB的调节功能。揭示转铁蛋白调控叶片衰老的机制，对于通过分子育种提高作物产量和品质具有重要意义。虽然近年来叶片衰老研究取得了重大进展，但我们对这一过程的分子调控机制的理解仍然不完全。本文还讨论了叶片衰老研究面临的挑战和机遇，并提出了应对策略。
Leaf senescence is a complex biological process regulated at multiple levels, including chromatin remodeling, transcription, post-transcription, translation, and post-translational modifications. Transcription factors (TFs) are crucial regulators of leaf senescence, with NAC and WRKY families being the most studied. This review summarizes the progress made in understanding the regulatory roles of these families in leaf senescence in Arabidopsis and various crops such as wheat, maize, sorghum, and rice. Additionally, we review the regulatory functions of other families, such as ERF, bHLH, bZIP, and MYB. Unraveling the mechanisms of leaf senescence regulated by TFs has the potential to improve crop yield and quality through molecular breeding. While significant progress has been made in leaf senescence research in recent years, our understanding of the molecular regulatory mechanisms underlying this process is still incomplete. This review also discusses the challenges and opportunities in leaf senescence research, with suggestions for possible strategies to address them.
