摘要:
种子萌发受到许多外界和内部因素的严格调控，激素可通过整合内源信号和环境信号协调调控种子萌发。现重点概述了脱落酸（abscisic acid,ABA）和赤霉素（gibberellins,GA）的信号互作及对光照、温度的响应，ABA和乙烯之间的信号互作。指出转录因子FUS3不仅是ABA和GA信号转导途径的枢纽节点，还能通过前馈和反馈调控回路控制种子成熟过程中ABA的积累。而且FUS3在ABA和乙烯的互作中也起重要作用，它负调控乙烯生物合成和信号转导基因的表达。此外，RGL2、XERICO和ABI5也是ABA和GA信号转导途径的枢纽位点。种子响应光质的ABA和GA调控枢纽元件是PIL5/PIF1。而在正反馈调控回路中，高温下种子ABA/GA比例的增高可维持较高的FUS3蛋白含量水平增强ABA的响应。
Abstract:
Seed germination is strictly regulated by many external and internal factors.The regulation of seed germination is integrated by endogenous and environmental signals.The cross talk between abscisic acid and gibberellins,and its response to light and temperature,as well as the cross talk of abscisic acid and ethylene were emphasized in this paper.It is showed that not only does FUS3 represent a node of cross-talk between ABA and GA signal,but also it established feedback and feedforward regulatory loops that result in the amplification of the ABA response during seed maturation.FUS3 also played a critical role in the cross-talk between ABA and ethylene.It negatively regulated the expression of ethylene biosynthesis and signaling genes.Moreover,RGL2,XERICO and ABI5 represented hubs between ABA and GA signal.The switch responsible for ABA and GA regulation in response to light quality was the PIL5/PIF1.In a positive-feedback loop,an increased ABA/GA ratio at high temperatures probably maintained a higher FUS3 protein level and enhanced the ABA response.
