水稻叶片衰老相关基因研究进展

Research Progress of Leaf Senescence Associated Genes in Rice

水稻(Oryza sativa L.)是世界上最主要的粮食作物之一。水稻叶片的衰老是制约水稻产量和品质的重要因素,同时也是一个多因素调控的过程,其相关基因的研究有助于明晰叶片衰老分子机理,从而为优质高产的品种选育提供理论和实践基础。本研究综述了水稻叶片衰老的形态学和生理生化变化、分子机制以及相关的影响因素,且汇总了近年来水稻叶片衰老相关基因的研究成果,以期探讨和寻找抑制水稻叶片衰老进程的有效方法,从而为水稻的增产及高产水稻品种的选育提供理论参考和保障。

Rice（Oryza sativa L.） is one of the most important crops in the world. Rice leaf senescence is an important factor restricting the yield and quality of rice, and is a process regulated by kinds of factors, the studies of related genes help clarify the molecular mechanism of leaf senescence, so as to provide theoretical and practical basis for the breeding of high quality and high yield. This review summarizes the morphological and physiological changes, molecular mechanism and related influencing factors of rice leaf senescence, and also summarizes recent studies related to rice leaf senescence associated genes, so as to explore and find the effective method to inhibit the senescence of rice leaves, and provide theoretical reference and support for improving rice yield and high-yield rice breeding.
