| 摘 要： | 植物杂种优势在生产上已被广泛应用,对提高产量和改善品质有重要意义,而生产杂交种的重要途径是细胞质不育及其恢复系统。在杂交品种选育过程中,优良恢复系选育至关重要。近年来植物细胞质雄性不育性恢复的分子机理一直是分子生物学的研究热点。本文综述了目前恢复基因研究的主要进展,讨论了恢复基因的遗传与定位。认为细胞质雄性不育恢复基因一般为单基因或少数显性效应主效基因,且恢复基因间作用方式多样化。目前,玉米Rf2基因、矮牵牛Rf基因、水稻Rf-1基因、萝卜Rfo基因都已被克隆。在这些恢复基因的克隆与分离基础上,本文讨论了恢复基因的结构特征及分子机理,认为恢复基因的可能分子机理,一种是恢复基因抑制细胞质雄性不育（CMS）特异ORF的表达,另一种是恢复基因补偿线粒体功能的缺陷。本文最后对恢复基因在植物分子育种上的应用前景提出了看法。

| Abstract: | Plant heterosis that leads to higher yields and fine quality has been wildly utilized, and cytoplasmic male sterility and fertility restorer (Rf) is essential to produce hybrid seeds. To develop elite fertility restorer lines is essential to selecting a hybrid combination with high heterosis. In recent years, the mechanism of fertility restoration has become a study hot spot. This paper reviewed the major development of molecular biological research on the Rf gene for cytoplasmic male sterility in plant. Ba... |
