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.
