OsNRAMP2 facilitates Cd efflux from vacuoles and contributes to the difference in grain Cd accumulation between japonica and indica rice
Rice (Oryza sativa L.) Cadmium OsNRAMP2 Haplotype
2023/4/21
Cadmium (Cd) accumulation in rice grain is of health concern. Identifying genes involved in grain Cd accumulation and performing molecular breeding may reduce it. In this study, knockout of OsNRAMP2, ...
Ef-cd基因是位于水稻第3染色体短臂上的一个显性早熟基因。本研究以早籼核不育系6442S-7为Ef-cd基因的供体亲本，通过连续回交与自交以及分子标记辅助选择，分离了Ef-cd基因，分别构建了以迟熟籼稻品系明恢63、蜀恢881和蜀恢527为受体亲本（遗传背景）的近等基因系，并在此基础上探明Ef-cd基因在纯合及杂合状态下一般可使水稻提早抽穗11～14 d。Ef-cd基因对促进水稻早熟与高产的有机...
