A heritable glucosinolate polymorphism within natural populations of Barbarea vulgaris

HPLC analyses of different organs of Barbarea vulgaris from natural populations in Europe revealed a heritable glucosinolate polymorphism. The most common glucosinolate profile is dominated (94%) by the hydroxylated form, (S)-2-hydroxy-2-phenylethyl-glucosinolate (BAR-type), whereas in the other type 2-phenylethyl-glucosinolate (NAS-type) was most prominent (82%).
