摘要: Glucosinolates are a category of secondary products present primarily in species the order Capparales. When tissue is damaged, for example by herbivory, glucosinolates degraded reaction catalyzed thioglucosidases, denoted myrosinases, also these species. Thereby, toxic compounds such as nitriles, isothiocyanates, epithionitriles and thiocyanates released. The glucosinolate-myrosinase system generally believed to be part plant’s defense against insects, possibly pathogens. In this review, evolution its impact on interaction between plants insects discussed. Further, data suggesting additional functions pathogens sulfur metabolism reviewed.
