Senescence in green plants is a complex and highly regulated process that occurs as part of plant development or can be prematurely induced by stress. In the last decade, the main focus of research has been on the identification of senescence mutants, as well as on genes that show enhanced expression during senescence. Analysis of these is beginning to expand our understanding of the processes by which senescence functions. Recent rapid advances in genomics resources, especially for the model plant species Arabidopsis, are providing scientists with a dazzling array of tools for the identification and functional analysis of the genes and pathways involved in senescence. In this review, we present the current understanding of the mechanisms by which plants control senescence and the processes that are involved.
绿色植物的衰老过程复杂且受到高度调控，它既是植物发育的一部分，也可能因胁迫而提前诱导发生。在过去十年中，研究的主要焦点一直是衰老突变体的鉴定，以及在衰老过程中表达增强的基因。对这些的分析开始拓展我们对衰老发挥作用过程的理解。基因组学资源最近的快速进展，尤其是针对模式植物拟南芥的进展，为科学家提供了一系列令人眼花缭乱的工具，用于鉴定和功能分析参与衰老的基因和途径。在本综述中，我们阐述了目前对植物控制衰老的机制以及所涉及过程的理解。
