The phytopathogenic necrotrophic fungus Sclerotinia sclerotiorum secretes large amounts of oxalic acid and cell wall-degrading enzymes (CWDE). Enzyme synthesis is pH dependent and subject to carbon catabolite repression. Because of the possible involvement of the glucose repressor CRE1 in the transc...
