衰老和程序性细胞死亡是植物发育的重要特征。通过在植物生命的整个过程中实现养分循环和重新分配，衰老有助于植物的生存和发育计划。这篇综述首先提出了全球整个植物生命故事中衰老的概念，重点是开花所施加的控制。然后重点关注叶片衰老及其对激素、营养物质和发育的控制。最后考虑了自噬和雷帕霉素靶标 (TOR) 激酶作为整合环境和内源信号的潜在调节剂的作用，这些信号控制细胞增殖、重编程和营养管理。 (C) 2010 年科学院。由 Elsevier Masson SAS 出版。版权所有。
Senescence and programmed cell death are important features for plant development. By allowing nutrient recycling and reallocation all along plant life, senescence contributes to the plant survival and the developmental program. This review first presents the concept of senescence in the global whole-plant life story, with an emphasis on the control exerted by flowering. It then focuses on leaf-senescence and its control by hormones, nutrients and development. The role of autophagy and of the Target of Rapamycin (TOR) kinase as potential regulators integrating environmental and endogenous signals, which control cell proliferation, reprogramming and nutrient management, is finally considered.
