摘要
镉是一种生物毒性极强,对人体健康危害极大的重金属。为了减少人体对镉的摄取,降低粮食作物中的镉含量,这对于确保食品安全具有重大意义。本综述将对水稻镉积累的遗传特性进行归纳分析,对水稻中镉的吸收和转运机理进行梳理。总结了最近几年水稻镉胁迫相关性状的基因QTL定位研究状况,对水稻镉积累相关的基因根据其功能性进行分类,此外介绍了水稻QTL定位作图群体的概况,旨在为镉低积累水稻品种的选育提供理论参考。最后提出其存在的问题与展望。
Cadmium is a kind of heavy metal that has extremely strong biological toxicity and is extremely harmful to human health. In order to reduce human cadmium uptake, cadmium content in food crops must be reduced,which is of great significance to ensure food safety. This review will summarize the genetic traits of cadmium accumulation in rice and examine the mechanism of cadmium uptake and translocation in rice. The status of QTLs related to cadmium stress-related traits in rice in recent years was summarized, and the genes related to cadmium accumulation in rice were classified according to their functionalities. In addition, the overview of QTL mapping populations in rice was introduced, aiming to provide theoretical reference for the breeding of rice varieties with low cadmium accumulation. Finally, its existing problems and prospects were put forward.
