As a unique and important germplasm resource in China, the Taigu male-sterile wheat has made significant contributions to wheat breeding. To further explore its potential application, this study aimed to establish an effective seed-stage identification system for the Taigu genic male sterility trait (Ms2) using molecular biology techniques, employing DsRed (encoding red fluorescent protein) and RUBY (a pigment biosynthesis-related gene) as reporter systems. Additionally, the single-copy semi-dwarf gene Rht-D1b was introduced to develop semi-dwarf, visually identifiable male sterile wheat. Through characterization of transgenic wheat plants and their progeny, the red fluorescent protein was efficiently expressed and stably inherited in wheat embryos. Although RUBY expression was undetected, effective identification of male sterility could still be achieved through red fluorescence. Sterile seeds with red fluorescence and fertile seeds without fluorescence exhibited a 1∶1 segregation ratio. T1 plants derived from red fluorescent seeds were all semi-dwarf and sterile, while those from non-fluorescent seeds were non-dwarf and fertile, indicating tight linkage among DsRed, Ms2, and Rht-D1b. The constructed reporter system not only enables fertility sorting at the seed stage via fluorescence but also addresses the excessive dwarfing issue in current dwarf-sterile wheat lines by incorporating the semi-dwarfing gene. This approach offers a novel tool for hybrid wheat production and recurrent selection breeding.

太谷核不育小麦作为中国特有的重要种质资源,在小麦育种中做出了重要贡献。为进一步挖掘其潜能,利用分子生物学技术,以编码红色荧光蛋白的DsRed和色素合成相关的RUBY基因为报告系统,对太谷核不育性状(Ms2)在种子时期进行鉴别,同时引入单拷贝Rht-D1b半矮秆基因,获得半矮化的种子可视化鉴定的雄性不育小麦。结果表明,通过对获得的转基因小麦植株及其后代的鉴定,红色荧光蛋白在小麦胚中高效表达且稳定遗传,虽然未能观察到RUBY报告基因的表达,但仍可通过红色荧光蛋白实现对雄性不育性状的有效鉴别,具有红色荧光的不育种子与无荧光的可育种子符合1∶1分离比,红色荧光籽粒所获得的T1植株均为矮秆不育株,无荧光籽粒的都为非矮秆可育植株,说明DsRedMs2Rht-D1b紧密连锁。由此可见,本实验所构建的报告系统不仅可以在种子阶段通过对籽粒荧光进行育性分选,同时引入半矮秆基因克服了目前常用的矮败小麦植株过低的问题,可为杂种小麦生产和轮回选择育种提供新工具。

太谷核不育小麦作为中国特有的重要种质资源,在小麦育种中做出了重要贡献。为进一步挖掘其潜能,利用分子生物学技术,以编码红色荧光蛋白的DsRed和色素合成相关的RUBY基因为报告系统,对太谷核不育性状(Ms2)在种子时期进行鉴别,同时引入单拷贝Rht-D1b半矮秆基因,获得半矮化的种子可视化鉴定的雄性不育小麦。结果表明,通过对获得的转基因小麦植株及其后代的鉴定,红色荧光蛋白在小麦胚中高效表达且稳定遗传,虽然未能观察到RUBY报告基因的表达,但仍可通过红色荧光蛋白实现对雄性不育性状的有效鉴别,具有红色荧光的不育种子与无荧光的可育种子符合1∶1分离比,红色荧光籽粒所获得的T1植株均为矮秆不育株,无荧光籽粒的都为非矮秆可育植株,说明DsRedMs2Rht-D1b紧密连锁。由此可见,本实验所构建的报告系统不仅可以在种子阶段通过对籽粒荧光进行育性分选,同时引入半矮秆基因克服了目前常用的矮败小麦植株过低的问题,可为杂种小麦生产和轮回选择育种提供新工具。

As a unique and important germplasm resource in China, the Taigu male-sterile wheat has made significant contributions to wheat breeding. To further explore its potential application, this study aimed to establish an effective seed-stage identification system for the Taigu genic male sterility trait (Ms2) using molecular biology techniques, employing DsRed (encoding red fluorescent protein) and RUBY (a pigment biosynthesis-related gene) as reporter systems. Additionally, the single-copy semi-dwarf gene Rht-D1b was introduced to develop semi-dwarf, visually identifiable male sterile wheat. Through characterization of transgenic wheat plants and their progeny, the red fluorescent protein was efficiently expressed and stably inherited in wheat embryos. Although RUBY expression was undetected, effective identification of male sterility could still be achieved through red fluorescence. Sterile seeds with red fluorescence and fertile seeds without fluorescence exhibited a 1∶1 segregation ratio. T1 plants derived from red fluorescent seeds were all semi-dwarf and sterile, while those from non-fluorescent seeds were non-dwarf and fertile, indicating tight linkage among DsRed, Ms2, and Rht-D1b. The constructed reporter system not only enables fertility sorting at the seed stage via fluorescence but also addresses the excessive dwarfing issue in current dwarf-sterile wheat lines by incorporating the semi-dwarfing gene. This approach offers a novel tool for hybrid wheat production and recurrent selection breeding.
