水稻籽粒铁(Fe)缺乏和镉(Cd)含量超标是农业生产亟待解决的重要问题。以往研究表明,OsVIT1和OsVIT2是液泡铁转运蛋白,本研究选取野生型ZH11为背景材料,使用胚乳特异性表达启动子Glb-1构建了胚乳过表达Os...展开更多 水稻籽粒铁(Fe)缺乏和镉(Cd)含量超标是农业生产亟待解决的重要问题。以往研究表明,OsVIT1和OsVIT2是液泡铁转运蛋白,本研究选取野生型ZH11为背景材料,使用胚乳特异性表达启动子Glb-1构建了胚乳过表达OsVIT1和OsVIT2材料。RT-qPCR分析表明,OsVIT1在转化植株的胚乳和叶片过量表达,OsVIT2在转化植株的胚乳过量表达。通过田间试验,研究胚乳过表达OsVIT1和OsVIT2对水稻不同部位Fe和Cd积...

Iron(Fe)deficiency and excess cadmium(Cd)in rice grain are important problems to be solved in agricultural production.Previous studies have shown that OsVIT1 and OsVIT2 are vacuolar iron transporters.In this study,wild-type ZH11 was selected as the background material a...MORE Iron(Fe)deficiency and excess cadmium(Cd)in rice grain are important problems to be solved in agricultural production.Previous studies have shown that OsVIT1 and OsVIT2 are vacuolar iron transporters.In this study,wild-type ZH11 was selected as the background material and...
