Recent studies on the differential expression of genes associated with leaf senescence support the long-standing interpretation of plant senescence as an organized, genetically controlled process. Sequence identities of genes that are differentially expressed in senescing leaves indicate roles in the salvage of nutrients. By considering this salvage function as the selected trait and the degeneration and death of the tissue a pleiotropic consequence of nutrient redistribution, the process of leaf senescence can be reconciled with evolutionary theories on the origins of senescence in animals.
最近关于与叶片衰老相关基因差异表达的研究支持了长期以来将植物衰老解释为一个有组织的、基因控制过程的观点。在衰老叶片中差异表达的基因的序列一致性表明其在养分回收中的作用。通过将这种回收功能视为被选择的性状，而组织的退化和死亡视为养分重新分配的多效性结果，叶片衰老过程可以与关于动物衰老起源的进化理论相协调。
