(2013) found decreased GST activity in susceptible sorghum cultivars during interaction with ScMV

In vitro studies showed that DHLA in addition to Co 2+ , Ni 2+ , Cd 2+ , Cu 2+ , Zn 2+ , Pb 2+ , and Hg 2+ also chelates Fe 3+ (its complex is more stable than that formed with Fe 2+ ), whereas ALA preferentially binds Mn 2+ , Cu 2+, Zn 2+ , and Pb 2+ but cannot chelate Fe 3+ [14,15]

NAC (N-acetylcysteine) provides an equally effective but slower alternative by supplying cysteine for endogenous glutathione synthesis at one-tenth the cost of liposomal glutathione

Among the many factors that might explain this difference are inter-species specificity in GST compartmentalization or chloroplast glutathione transporters, variation in leaf developmental stage, or the inclusion (or not) of inhibitors during the incubation
