they are nutrients in their own right
Given that GSH has a molecular weight similar to that of amino acids, a plausible scenario is that when plants experience mechanical damage or insect attack, a large volume of GSH from the intracellular region may surge into the apoplastic region, inducing calcium influx by activation of the GLR3.3 ion channel
It upregulates genes involved in collagen synthesis (COL1A1, COL3A1, COL5A1), extracellular matrix remodeling (decorin, fibromodulin), and antioxidant defense (superoxide dismutase, glutathione peroxidase) while simultaneously suppressing genes associated with inflammation (IL-6, TNF-alpha), fibrinogen production, and tissue destruction (several MMPs)
