摘要/Abstract

摘要： 植物激素脱落酸(abscisic acid ABA)可调控植物生长发育及应答病菌、干旱、高盐和低温等多种生物和非生物胁迫反应。从水生生物向陆生生物进化过程中ABA受体基因经历了从无到有的过程,ABA受体是ABA通路最上游的信号调节因子,能够识别ABA信号并启动信号转导。本文总结了ABA信号通路近年研究进展,包括ABA的转运与识别、ABA受体结构与功能的多样性等,同时阐明ABA核心信号通路是通过一个复杂的调控网络而相互作用。本文为通过改造核心ABA信号通路和ABA的运输系统来提高农作物的产量和品质提供了可参考的资料。

Abstract: Plant hormones abscisic acid (ABA) can regulate plant growth and development and response to various biotic and abiotic stresses such as pathogens, drought, high salinity and low temperature. Evolution research indicated that no ABA receptor gene appeared in aquatic plants but emerged in the first landing non-vascular plant group bryophytes. ABA receptor is the upstream signal regulator of ABA pathway, which can recognize ABA ligand and initiate signal transduction. This paper summarizes the recent research progress of ABA signaling pathway, including ABA transport and recognition, ABA receptor structure and function diversity, and the molecular network mechanism of the core signaling in ABA responses. This review could supply potential references for crop breeding on improving yield and quality by modifying the core ABA signaling pathway and ABA transport system.
