赤霉素(Gas)作为一种高效能的植物生长调节物质对棉纤维的分化和发育有着非常重要的影响, 但是, 一直以来有关赤霉素与棉纤维分化和发育的分子机制的研究还很少。文章论述了近年来GA信号组分、转导途径的分子生物学研究进展以及GA与棉纤维分子发育的相关研究成果, 旨在为揭示赤霉素调控棉纤维分化和发育的分子机制以及改善棉纤维品质的棉花育种工作提供新的思路。

Gibberellins (GAs) is a sort of high efficiency plant growth regulator which is very important for cotton fiber initiation and development. Recently, the research of GA signal transduction mostly focuses on Arabidopsis, wheat, barley, maize, rice and so on. Yet we know little about molecular mechanism of GA to cotton fiber initiation and development. In recent years, exciting progress has been made in identifying many important components involved in gibberellin signal transduction pathways, which can help us to understand deeply these pathways and their regulation. This review summarized the recently research process of GA signal transduction and correlation of GA and cotton fiber’ molecular development. We hope that the paper can provide some new ideas about the function and mechanism of GA in cotton fiber initiation and development, and for cotton breeding task.
