“…For example, the accumulation of GABA in apples stored under controlled atmosphere conditions is due to the highly conserved CaMBD of MdGAD1 and MdGAD2 , whose activity and spectral properties are regulated by Ca 2+ /CaM and acidic pH [ 109 ]. GAD is highly sensitive to the Ca 2+ /CaM complex in rice bran; when the concentrations of Ca 2+ and CaM are 200 μmol L −1 and 150 nmol L −1 , respectively, the GAD of rice bran is significantly increased, by three times [ 110 ]. In the presence of fructose, Ca 2+ and BoCaM2 levels in Broccoli sprouts have been raised to form Ca 2+ /CaM complexes that bind to GAD.…”

Role of Gamma-Aminobutyric Acid in Plant Defense Response

Gamma-aminobutyric acid (GABA) is a four-carbon non-protein amino acid that acts as a defense substance and a signaling molecule in various physiological processes, and which helps plants respond to biotic and abiotic stresses. This review focuses on the role of GABA’s synthetic and metabolic pathways in regulating primary plant metabolism, redistributing carbon and nitrogen resources, reducing the accumulation of reactive oxygen species, and improving plants’ tolerance of oxidative stress. This review also highlights the way in which GABA maintains intracellular pH homeostasis by acting as a buffer and activating H+-ATPase. In addition, calcium signals participate in the accumulation process of GABA under stress. Moreover, GABA also transmits calcium signals through receptors to trigger downstream signaling cascades. In conclusion, understanding the role of GABA in this defense response provides a theoretical basis for applying GABA in agriculture and forestry and feasible coping strategies for plants in complex and changeable environments.
