中文摘要：

赤霉素（gibberellins或gibberellic acid,GA）作为植物生长的必需激素之一,在植物生长发育的整个过程中发挥着至关重要的作用。近年来随着植物功能基因组学的发展和突变体的应用,对赤霉素信号转导途径领域的研究取得了较大的进展,并鉴定出了介入赤霉素信号转导过程的重要基因。其中,GAMYB基因是赤霉素信号转导途径中一个重要的转录因子。该文综述了赤霉素信号转导途径及其中间组分,以及转录因子GAMYB基因的研究进展。主要包括GAMYB基因的结构,基因在生长发育中的作用和大豆中GAMYB基因的研究及展望。

英文摘要：

Gibberellin（GA） is a common plant hormone that plays an important role in the growth and development in higher plants.In recent years,the power of molecular genetics has dramatically advanced our understanding of all aspects of GA signaling.Many genes encoding GA response pathway components have been identified using Arabidopsis and cereal mutants.GAMYB is one of the key MYB transcription factor that is expressed in response to GA.In this paper,research on the GA signal transduction,GA response pathway components and transcription factor GAMYB were reviewed.It included the structure of GAMYB,its regulation mechanism in diverse developmental processes and research on GAMYB gene in soybean.
