【摘要】 近年来国内外对植物细胞质雄性不育(cytoplasmicmalesterility,CMS)在细胞学、生理生化及分子遗传学等方面的研究又取得了新的进展。特别是对育性恢复基因的定位、克隆的研究已取得一定突破,发现编码含保守PPR(pentatricopeptiderepeat)模体蛋白的基因在多种植物中与育性恢复密切相关。更多还原

【Abstract】 In recent years, the new advances correlated with cytoplasmic male sterility (CMS) in the fields of cytology, biochemistry and molecular genetics, have been achieved. Especially in the cloning and identification of the restorer genes, great progress had been made. It indicates that some genes that encode proteins which have conservative pentatricopeptide repeat (PPR) motif are closely associated with fertility restoration in some CMS plants. In this paper, the recent advances all above are reviewed and the future research direction of it also discussed.更多还原
