Abstract: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 applied 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 ( Rf1) had been located in two BAC clones spanning an interval of approximately 100 kb, Rf2gene 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 research results on breeding high quality, high yield and high resistance cotton varieties.
