Effect of the expression of ZbMSN4 in S. cerevisiae strains BY4741 parental and derived deletion mutant msn4Δ (a) and W303-1A parental and derived double deletion mutant msn2Δmsn4Δ (b). Growth curves of S. cerevisiae parental strains BY4741 (a) and W303-1A (b) (filled symbols) and the corresponding derived deletion mutants msn4Δ (a) and msn2msn4Δ (b) (empty symbols) transformed either with the empty vector (,) or with pGREG506_promMSN4Sc_ZbMSN4 (□,■). S. cerevisiae BY4741 background strains were cultivated in MM4 medium (pH 4.0) without uracil or in this same basal medium supplemented with 65 mM (a), and S. cerevisiae W303-1A background strains were cultivated in MM5 medium (pH 4.0) without uracil or in this same basal medium supplemented with 60 mM (b). The growth curves shown are representative of three independent assays
