The Role of the ?-Aminobutyric Acid (GABA) in Plant Salt Stress Tolerance

?-Aminobutyric acid (GABA) is a non-protein amino that accumulates in many plant species response to environmental stress. A number of reverse-genetic experiments and omics analyses have revealed positive relationships between GABA levels tolerance stresses. Furthermore, the application exogenous has been demonstrated effectively reduce ROS levels, enhance membrane stability modulate phytohormones cross-talk, thus improving against multiple However, molecular mechanisms regulating homeostasis physiological functions plants remain largely unclear. In this review, we focus on recent achievements deciphering role genetic manipulations endogenous associated metabolites improve salt Finally, discuss regulation ion high-salinity conditions. These findings laid groundwork for future studies explore genetic, physiological, GABA-mediated improvements productivity under high-salt
