摘要: 植物的种子萌发和生长发育受到多种环境因素的制约。不良环境会造成种子萌发延迟,出苗不齐,幼苗素质减弱等,并可能引发植物的胁迫反应。γ-氨基丁酸(γ-aminobutyric acid,GABA)是一种近年来广泛应用于调节植物应激适应的信号物质。本研究通过阐述GABA在植物体中的作用,分析环境胁迫下GABA产生的生理机制,对环境胁迫下GABA如何调控植物种子萌发、幼苗形态发育、植物抗氧化作用、光合作用、氮代谢过程以及内源GABA代谢和多胺代谢过程进行总结。最后,针对GABA在调节植物抗逆性方面还未解决的问题进行讨论,对GABA的应用前景进行展望,以期为与GABA相关的研究和此物质的实际应用提供理论参考。

Abstract: Seed germination,growth,and development of plants are restricted by many environmental factors.An adverse environment will cause postponing seed germination,irregular emergence,slim seedlings and so on,and may lead to severe responses of plants to the stress.(γ-Aminobutyric acid,GABA) is a signal substance widely used in regulating plant stress adaptation in recent years.This study described the role of GABA in plants,analyzed the physiological mechanism of GABA production under environmental stresses,and reviewed how GABA regulates plant seed germination,seedling morphological development,plant antioxidant effect,photosynthesis,nitrogen metabolism,endogenous GABA metabolism,and polyamine metabolism under environmental stress.Finally,we discussed some unsolved scientific questions about GABA in regulating plant stress resistance and prospected the application prospect of GABA.This review may provide theoretical reference for the research related to GABA and the practical application of this substance.

Key words: γ-aminobutyric acid, Environmental stress, Seed germination, Antioxidation, Photosynthesis, Metabolism
