摘要:
γ-氨基丁酸(GABA)是一种广泛分布于生物体内的非蛋白氨基酸，在动物神经系统中作为关键信号分子发挥重要作用。近年研究发现，GABA在植物中同样承担重要的调控功能，尤其在非生物胁迫响应中表现出显著的生理调控作用。植物在生长过程中常面临干旱、洪涝、盐碱、极端温度及重金属等胁迫环境，GABA可通过多重协同机制增强植物抗逆性，包括：(1)激活抗氧化防御系统；(2)调节渗透平衡；(3)动态平衡碳氮代谢；(4)参与Ca2+/pH值/ROS信号串联及植物激素(如脱落酸、乙烯)网络调控，形成多层次胁迫响应体系。本文系统综述了非生物胁迫下植物GABA代谢的核心途径及其分子调控机制，重点解析了谷氨酸脱羧酶(GAD)、GABA转氨酶(GABA-T)及琥珀酸半醛脱氢酶(SSADH)等关键酶的动态活性调控、胁迫特异性信号通路的触发模式，以及GABA通过表观遗传修饰介导的长期适应性。基于现有研究，未来可聚焦下游信号转导的分子机制、基因编辑技术以及高效外源GABA的高效施用方法，以促进农业高质量发展。
