Which secondary metabolites (or types) are specific for the Brassicaceae family? We are studying an enzyme family involved in secondary metabolite formation of which one member is specific for Brassicaceae. Therefore, this family member could be involved in the biosynthesis of such Brassicaceae specific metabolites.
Specific for the Brassicaceae family are the glucosinolates. They are common in all Brassicales plants.
Dear Olga and Sascha,
Thanks for your help. Now we know which pathway to look at for possible involvement of this enzyme.
Eric, it was a lot of speculations and some research data on correlation between specific glucosinolates composition and plant reaction to pathogens and pests. Including Arabidopsis landrace "Columbia", a subject of many resistance-related studies, that have very special glucosinolates, but nobody tried to link this feature to its high resistance to many pathogens.
Good luck!
Alex
Glucosinolates are sulfur- and nitrogen-containing plant secondary metabolites common in the Brassicaceae and related plant families. In the plant, they coexist with an endogenous ?-thioglucosidase called myrosinase, though glucosinolates are stored in the vacuoles of so-called S-cells and myrosinase in separate but adjacent cells. Upon plant tissue disruption, glucosinolates are released at the damage site and become hydrolyzed by myrosinase.
