摘要: 植物叶片衰老是叶片发育的最终阶段, 也是植物在长期进化过程中形成的适应性机制。水稻(Oryza sativa)叶片的衰老对其产量和品质影响极大, 相关研究主要集中在早衰。该文综述了水稻早衰及其调控基因的研究进展, 尤其对水稻叶片早衰的形成原因、发生过程、生理变化及防治措施进行了阐述, 以期为深入解析水稻早衰的分子机制奠定理论基础, 同时为水稻育种提供参考。

Abstract: Senescence of plant leaves is the final stage of leaf development as well as a adaptive performance of the long-term evolution of plants. The senescence of rice (Oryza sativa) leaves greatly affects the quality and yield of rice. Study of leaf senescence has mainly focused on pre-senility. This paper reviews the research progress in rice senescence and genes related to rice senescence, especially advanced suggestions about the causes, the process, and physiological changes of rice leaf senescence and how to prevent senescence. These studies establish a theoretical foundation for further analysis of the molecular mechanism of rice premature senescence and provide some reference for rice breeding as well.
