- 摘要:
- 植物激素脱落酸（ABA）参与从种子萌发到植物开花、结果和衰老等多个生长发育过程。研究ABA细胞信号转导的分子机制对进一步阐明其功能具有重要的意义。通过介绍FCA（Flowering Control Locus A）、Mg离子螯合酶H亚基(ABAR/CHLH)、G蛋白偶联受体（GCR2）、GTG1/GTG2（GPCR-type G-Proteins1/2）和PYR1/PYL/RCAR在ABA信号传导途径中的作用模式，阐述了其能够接受ABA信号并激活相关下游组分，从而完成其生理功能。
- Abstract:
- Phytohorme abscisic acid(ABA)plays a pivotal role in various processes involved in seeds germination and maturation,plant flowering and organ senescence.Study on how ABA signals are perceived and relayed is necessary for dissecting its molecular functions in higher plant.The functions of accepting ABA signal and activating related downstream component so as to complete physiological function were elaborated through introducing the action modes of FCA,ABAR/CHLH),GCR2,GTG1/GTG2 and PYR1/PYL/RCAR in perceiving ABA’s signal.
