水稻滞绿突变分子遗传研究进展

Advances in molecular genetics of rice stay green mutation

水稻是中国最重要的粮食作物,水稻滞绿突变的分子遗传研究对于延缓水稻衰老以及提高水稻生物产量方面具有重要的意义。本文从植物滞绿突变的概念、分类,水稻滞绿突变基因的克隆与功能分析,以及在水稻高产育种上的应用进行了综述,探讨水稻滞绿突变基因的分子遗传机制,以期为水稻超高产育种及挖掘水稻高产潜力的种质资源提供理论依据。

Rice is the most important food crop in China. Molecular genetic research on rice stay green mutation is of great significance in delaying rice senescence and increasing rice biological yield. In this paper, the concept and classification of plant stay-green mutation, the cloning and functional analysis of rice stay-green mutation gene, and the application in rice high-yield breeding were reviewed. The molecular genetic mechanism of rice green mutation gene was explored to provide a theoretical basis for rice high-yield breeding and exploitation of germplasm resources with high yield potential.
