Interaction of cruciferous phytoanticipins with plant fungal pathogens: Indole glucosinolates are not metabolized but the corresponding desulfo-derivatives and nitriles are

► Indole desulfo-glucosinolates are transformed by Rhizoctonia solani and Sclerotinia sclerotiorum. ► Indolyl-3-acetonitriles and indolyl-3-methanol are transformed by three phytopathogens. ► Myrosinase activity is detected in mycelia of Alternaria brassicicola. ► Antifungal activities of indolyl-3-methanol and diindolyl-3-methane are evaluated.
