| 摘 要： | 稻米镉污染已成为全球粮食安全的一个重大问题。系统了解水稻体内镉响应基因调控机制及镉代谢的影响因素有助于推动低镉优质水稻新品种的培育。本文重点阐述了镉进入根细胞、镉从根转移至茎、从茎转移至籽粒的三种机制及主要影响因素,同时对目前已知的水稻镉代谢调控相关基因进行了综述,以期为利用分子育种技术选育低镉积累水稻品种提供参考。

| Abstract: | In recent years,cadmium pollution in rice has become a serious problem with the security of global food.Systematic understandings the regulation mechanism of cadmium responsive gene and the factors affecting cadmium metabolism are helpful for breeding new rice varieties with low cadmium accumulation and high quality.This review focused on the mechanisms of cadmium absorption from the soil,transportation from root to shoot and accumulation in rice grains,and elaborated the influencing factors and summarized the studies on genes involved in cadmium metabolism in rice,which was aimed to provide references for breeding rice with low cadmium accumulation by molecular design breeding. |
