Aging, stress, and senescence in plants are interconnected processes that determine longevity. We focus here on compiling and discussing our current knowledge on the mechanisms of development that long-lived perennial plants have evolved to prevent and delay senescence. Clonal and nonclonal perennial herbs of various life forms and longevities will be particularly considered to illustrate what biological diversity can teach us about aging as a universal phenomenon. Source-sink relations and redox signaling will also be discussed as examples of regulatory mechanisms of senescence at the organ level. Whether or not effective mechanisms that biological diversity has evolved to completely prevent the wear and tear of aging will be applicable to human aging in the near future ultimately depends on ethical aspects.
植物的衰老、应激和衰老都是相互关联的过程，决定着植物的寿命。在这里，我们专注于收集和讨论我们目前对长寿多年生植物进化出的防止和延缓衰老的发育机制的了解。各种生活形式和寿命的无性和有性多年生草本植物将被特别考虑，以说明生物多样性可以告诉我们什么是普遍现象的衰老。还将讨论源库关系和氧化还原信号，作为器官水平衰老调控机制的例子。生物多样性进化出的有效机制是否可以完全防止衰老的损耗，在不久的将来是否适用于人类的衰老，最终取决于伦理方面。
