Exogenous γ-aminobutyric acid mitigates physiological and transcriptomic responses of Prunus mongolica under combined alkali salt and cadmium stress
Introduction Prunus mongolica is a relict xerophytic shrub important for desert ecosystem stability and vegetation restoration in arid regions. However, its adaptive mechanisms under combined alkali salt and cadmium stress remain unclear. This study investigated the regulatory role of exogenous γ-aminobutyric acid (GAB...
