γ-Aminobutyric Acid (GABA) and Amino Acid Metabolism Crosstalk in Plant Growth Regulation and Stress Response

GABA and Amino Acid Metabolism Crosstalk in Plant Growth Regulation and Stress Response

γ-Aminobutyric acid (GABA) is a non-protein amino acid widely distributed in plants and plays a central role in regulating growth, maintaining cellular homeostasis, and mediating responses to biotic and abiotic stresses. As both a metabolic intermediate and signaling molecule, GABA integrates with multiple amino acid metabolic pathways, forming a highly coordinated regulatory network that supports …
