WebA 3-fold increase in cysteine and glutathione content was observed in wild-type plants exposed to salt stress, but not in the transgenic plants. The induction of cysteine and glutathione synthesis during salt stress in the wild-type plants suggests a possible protective mechanism against salt-induced oxidative damage. WebApr 12, 2024 · A very important factor controlling the plant glutathione level is availability of cysteine (Noctor et al., 2002). The upregulation of cysteine and GSH synthesis under stress may be related to sulfur assimilation and metabolism, which is regulated in a demand−driven manner (Koprivova and Kopriva, 2014; Koprivova and Kopriva, 2024).
