| 摘 要： | 植物激素赤霉素(GA)参与植物种子萌发、茎伸长、开花、结果等多个生长发育过程.研究GA细胞信号转导的分子机制对进一步阐明其生物学功能具有重要的意义.GA合成突变体和细胞信号转导突变体的研究表明,GAI及其同功蛋白具有受体功能,GA被受体识别后进一步与DELLA蛋白作用,从而解除DELLA蛋白对植物生长的抑制作用.文章主要综述这些分子具体的作用模式.

| Abstract: | Phytohorme abscisic acids(GA) play a pivotal role in various processes involved in seeds germination and shoot elongation,plant flowering and seed maturation.Study on how GA signals are perceived and relayed is necessary for dissecting its molecular functions in higher plant.Although many molecules containing GAI,DELLA and SCF are known as putative signal components for perceiving and relaying Ga'signals,the molecular mechanism of GA are largely unknown.This paper will discuss how these molecules work. |
