本发明公开了一种水稻金属转运基因OsNRAMP2及其应用.本发明首次证明了水稻OsNRAMP2基因是水稻镉转运和积累的功能基因,所述水稻OsNRAMP2基因碱基序列如SEQ ID NO.1所示.本发明通过试验证明水稻OsNRAMP2基因敲除可以显著降低水稻地上部分镉转移率,显著降低谷粒中的镉含量.这对于研究水稻镉积累遗传机制,多途径组合降低...
本发明公开了一种OsNRAMP2基因的低镉基因型及其应用,属于农业生物技术领域.本发明公开了OsNRAMP2基因的低镉基因型,相比于高镉基因型(Hap2,Hap3,Hap4),OsNRAMP2基因的低镉基因型(Hap1)在3号染色体5659037位置处插入了6个核苷酸.本发明鉴定到OsNRAMP2基因与籼粳稻的分化有关,粳稻为Hap1,谷粒镉浓度较低,籼稻为...
At filling stage, OsNRAMP2 was highly expressed in all tissues except for husk, suggesting its role in Cd remobilization. Changes in OsNRAMP2 expression affected the concentrations of Fe, Mn, Zn, and Cu in grain and also affected rice growth. Phylogenetic analysis showed...
