中文摘要：

棉花生殖器官发育与棉花的经济价值紧密相关，因此一直以来都是研究热点。随着棉花三系育种体系的应用推广，棉纤维发育相关基因的克隆、棉花生殖器官高效表达启动子的克隆和应用，棉花生殖器官发育的分子生物学研究的重要性也日益凸显。为方便相关研究人员了解该领域的最新进展，就国内外在棉花核质互作雄性不育、核不育、棉纤维发育以及棉花生殖器官特异型启动子等方面取得的分子生物学研究进展作了详细介绍，并对以上各方面的研究趋势进行了展望。

英文摘要：

Cotton reproductive organ development is correlative with cotton economic value tightly, it＇s always the focus of cotton molecular biology research. Research in this field by molecular biology, is not only helping us understand cotton reproductive organ development mechanism, but also can be ap- plied in cotton production. At present, researchers have made great progress in this field. For example, researchers get more information about cotton cytoplasmic male sterility （CMS） and genome male sterility （GMS）, restorer fertility gene 1 （Rfl） had been located in two BAC clones spanning an interval of approximately 100 kb, Rf2 gene had been located in a genetic map with 9 markers in a genetic distance of 2.9 cM; cotton GMS line with yellow bud marker had been found. On the other hand, cotton fiber development related genes had been mapped by quantitative trait loci （QTL）;by studying the transcriptome and regulation of cotton fiber development, some cotton fiber elongation related genes had been cloned; furthermore, some cotton reproductive organ specific promoters had been cloned. It＇s hoped that the review could provide reference for further research and application the re- search results on breeding high quality, high yield and high resistance cotton varieties.
