摘要
植物细胞质雄性不育(cytoplasmic male sterility,CMS)是作物杂种优势利用的重要途径,是由线粒体不育基因和相应的核编码育性恢复基因(fertility restorer gene,Rf)互作产生。随着分子生物学和分子遗传学的发展,许多植物的大量Rf基因被定位和克隆,尤其是近年来一些植物CMS及其育性恢复的机制也得到了阐明。本文概述了几种主要农作物中已经定位或克隆的Rf基因及其作用机制的最新研究进展,并对未来该领域的研究方向进行了展望。
Cytoplasmic male sterility （CMS） in plants is an important way of utilizing of heterosis in crops, which is controlled by interactions of mitochondrial sterile gene and nuclear fertility restorer gene （Rf）. With the development of molecular biology and molecular genetics, a mass of Rf genes from different crops were mapped and cloned, facilitating our understanding of the mechanism of CMS and fertility restoration. This article summarized the progress on mapping and cloning of Rf genes and their possible action mechanisms in fertility restoration in several crops, and trends in further study strategies in this field were discussed.
