Effect of abiotic stress on glucosinolates (GLS)/allyl-isothiocyanates (ITC) content. (1) The chain-elongation steps of glucosinolates biosynthesis are affected by abiotic stress; (2) Stress perception may lead to increased synthesis of any secondary messenger in the cytosol, facilitating the release of the glucosinolates to the cytoplasm from the vacuole (3). The activity of plant myrosinases will product (allyl-) isothiocyanates (4) that might regulate the transduction or accumulation of other transporters or channels in the plasma membrane (5).
