雄性不育是植物育种和杂交制种的重要性状。普通小麦显性雄性不育基因Ms2已在我国育成了数百个小麦新品系和新品种。在这里，我们描述了Ms2基因的图位克隆，并表明Ms2赋予小麦，大麦和短柄草雄性不育。MS 2在小麦族中是一个孤儿基因，其在花药中的表达与在启动子中插入一个反转录元件有关。Ms2的克隆具有组装小麦轮回选择和杂交种子生产的实用管道的巨大潜力。显性雄性不育基因Ms2在我国培育出了数百个小麦新品系和新品种。在这里，Ni等人描述了Ms2基因的克隆，该基因在小麦亚科中作为孤儿基因出现，并表明Ms2可用于赋予小麦、大麦和短柄草属的雄性不育性。
Male sterility is a valuable trait for plant breeding and hybrid seed production. The dominant male-sterile gene Ms2 in common wheat has facilitated the release of hundreds of breeding lines and cultivars in China. Here, we describe the map-based cloning of the Ms2 gene and show that Ms2 confers male sterility in wheat, barley and Brachypodium. MS2 appears as an orphan gene within the Triticinae and expression of Ms2 in anthers is associated with insertion of a retroelement into the promoter. The cloning of Ms2 has substantial potential to assemble practical pipelines for recurrent selection and hybrid seed production in wheat. The dominant male-sterile gene Ms2 has facilitated the release of hundreds of wheat-breeding lines and cultivars in China. Here Ni et al. describe the cloning of the Ms2 gene, which appears as an orphan gene in the Triticinae, and show that Ms2 can be used to confer male sterility in wheat, barley and Brachypodium.
