植物早衰的分子机理研究进展

衰老是显花植物生活周期中必然经历的阶段.植物衰老伴随着一系列的生理变化,而这些变化受到各种环境因子的影响,但主要受衰老相关基因的作用.这些基因包括发育进程相关基因、激素合成相关基因、调节基因、参与调节因子降解过程的基因、植物防卫反应相关基因等.最近的研究表明,植物衰老还受到蛋白的亚硝基化这种蛋白翻译后修饰途径的调控.

Progress in Molecular Mechanism Underlying Plant Premature Senescence

Senescence,integral to the flowering plant life-cycle,is affected by not only endogenous developmental factors but also various environmental factors.Increasing efforts have been made to identify senescence-associated genes.In this paper,the authors summarized the functions of the genes that had been identified,including:genes that control the developmental aging process,genes that control other endogenous biological processes,regulatory genes,genes that are supposed to be involved in the degradation proces...
