植物叶片衰老研究进展

Research Progress on Plant Leaf Senescence

叶片衰老是植物叶片生长发育过程中衰变的重要信号,在此综述了植物叶片衰老的特性、机理、与叶片衰老相关的基因、影响叶片衰老的因子(即器官、植物激素、氧化胁迫等),同时又介绍了叶片衰老相关基因表达的调控,并对开展植物叶片衰老研究的综合发展趋势作了分析。

Leaf senescence is an important disintegration signal in the stage of plant leaf growth process. This paper reviewed the characteristics, mechanism, senescence-associated genes, affecting factor （organ, phytohormone, oxidation intimidate etc.） of plant leaf senescence, as well as the molecular regulation and control of gene expressing in plant leaf senescence. Also, we analyzed general direction of plant leaf senescence research at present.
