Physiological and Transcriptomic Analyses Reveal the Mechanisms of Exogenous GABA in Alleviating Cadmium Toxicity in Two Grape Cultivars
The control group (CK) received treatment with 1/2 Hoagland solution, the Cd treatment group (CD) received treatment with Cd solution (1/2 Hoagland solution containing 0.2 mmol L-1 CdCl2), and the combined Cd-GABA treatment group (GC) received treatment with Cd and GABA solution (1/2 Hoagland solution containing 2 mmol L-1 CdCl2 and 2.5 mmol-1 GABA).
