TionsFungal strains applied in this study are listed in Table 1. Media utilised include glucose minimal media (GMM) [41], YGT (0.five yeast extract, two dextrose, trace components prepared as described [41], and oat meal media (OMM) (1 oat meal). Supplements for auxotrophic markers have been added as required [41]. Glucose was substituted with threonine (100 mM) in threonine minimal medium (TMM) for induction of alcA promoter. Strong medium was ready by adding 10 g/liter agar. Strains have been stored as 30 glycerol stocks at 280uC.Genetic TechniquesMeiotic recombination between A. nidulans strains was carried out as previously described [42]. Progeny in the cross among the RM7 mutant [40] and RAV2 (yA2, wA3, argB2, DstcE::argB, pyroA4) have been analyzed for the presence or absence of veA by PCR. Colony morphology, as well as norsolorinic acid (NOR) production, have been also studied. The progeny of this cross showed 4 phenotypic groups: 1. DveA, DstcE, X- (RM7 parental kind); 2. DstcE (RAV2 parental form); three.Price of 91511-38-5 recombinant DveA, DstcE (RM7R1) and recombinant DstcE, X- (RM7-R2). Dominance test was carried out by forming diploids with RM7-R2 and RAV1 strain.Table two.
