小麦avenin—like type—B基因启动子的克隆及功能验证
为深入研究ALP type-B基因的调控机理及胚胎特异性表达特性,采用农杆菌转化技术.将含有ALP type—B基因启动子的双元表达载体转化烟草。对阳性转基因烟草植株进行GUS组织化学检测定性分析。结果显示,小麦ALP type—B基因启动子可驱动报告基因在烟草种子的胚乳中特异表达,在其他组织中没有表达。...

Histochemical GUS staining on transgenic tobacco plants showed that ALP type-B promoter was an endospermspecific promoter which can dr |
