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 summa- rized the recently research process of GA signal transduction and correlation of GA and cotton fiber’ molecular develop- ment. We hope that the paper can provide some new ideas about the function and mechanism of GA in cott
