 Another option would be to use techniques in genetic engineering to introduce the glucosinolate-myrosinase system in crops as a means of fortifying their resistance against pests.Isothiocyanates, the primary product of glucosinolate hydrolysis, have been known to prevent iodine uptake in the thyroid, causing goiters.Isothiocyanates in high concentrations have also been known to cause hepatotoxicity, or liver damage.
