叶片衰老是一个复杂的发育阶段，涉及退化和营养循环过程。其特征在于叶绿素的损失和蛋白质、核酸、脂质的降解以及营养物质的再活化。叶片衰老的发生和进展受一系列环境因素（如干旱、黑暗、极端温度和病原体攻击）和内源因素（包括年龄、乙烯、茉莉酸、水杨酸、脱落酸和细胞分裂素）控制。本文综述了近几年来在叶片衰老过程中的信号转导、黑暗和干旱介导的叶片衰老以及调节叶片衰老的各种激素等方面的研究进展。不同的信号对叶片衰老的调控机制不同，不同信号通路之间的相互作用使叶片衰老的调控更加复杂。关键的衰老调控网络仍然需要阐明，包括各种环境信号和内部因素的交互作用和相互作用机制。
Leaf senescence is a complex developmental phase that involves both degenerative and nutrient recycling processes. It is characterized by loss of chlorophyll and the degradation of proteins, nucleic acids, lipids, and nutrient remobilization. The onset and progression of leaf senescence are controlled by an array of environmental cues (such as drought, darkness, extreme temperatures, and pathogen attack) and endogenous factors (including age, ethylene, jasmonic acid, salicylic acid, abscisic acid, and cytokinin). This review discusses the major breakthroughs in signal transduction during the onset of leaf senescence, in dark- and drought-mediated leaf senescence, and in various hormones regulating leaf senescence achieved in the past several years. Various signals show different mechanisms of controlling leaf senescence, and cross-talks between different signaling pathways make it more complex. Key senescence regulatory networks still need to be elucidated, including cross-talks and the interaction mechanisms of various environmental signals and internal factors.
