Gamma-aminobutyric acid (GABA), a ubiquitous non-protein 4-carbon amino acid present in both prokaryotic and eukaryotic organisms. It is conventionally recognized as a neurotransmitter in mammals and plays a crucial role in plants. The context of this review centers on the impact of GABA in mitigating abiotic stresses induced by climate change, such as drought, salinity, heat, and heavy metal exposure. Beyond its neurotransmitter role, GABA emerges as a key player in diverse metabolic processes, safeguarding plants against multifaceted abiotic as well as biotic challenges. This comprehensive exploration delves into the GABA biosynthetic pathway, its transport mechanisms, and its intricate interplay with various abiotic stresses. The discussion extends to the nuanced relationship between GABA and phytohormones during abiotic stress acclimation, offering insights into the strategic development of mitigation strategies against these stresses. The delineation of GABA's crosstalk with phytohormones underscores its pivotal role in formulating crucial strategies for abiotic stress alleviation in plants.
γ-氨基丁酸（GABA）是一种普遍存在于原核生物和真核生物中的非蛋白质四碳氨基酸。传统上，它被认为是哺乳动物中的一种神经递质，在植物中也起着至关重要的作用。本综述的重点是GABA在减轻气候变化引起的非生物胁迫（如干旱、盐度、高温和重金属暴露）方面的影响。除了其神经递质作用外，GABA在多种代谢过程中也成为关键参与者，保护植物免受多方面的非生物和生物挑战。本次全面探索深入研究了GABA的生物合成途径、转运机制及其与各种非生物胁迫的复杂相互作用。讨论还扩展到非生物胁迫适应过程中GABA与植物激素之间的细微关系，为针对这些胁迫的缓解策略的战略发展提供见解。GABA与植物激素的相互作用的描述强调了其在制定植物非生物胁迫缓解关键策略中的关键作用。
