(B) ChIP analysis of H3K4me3 presence at ADH1, PMA1 and YEF3 promoter (P) and 5'ORF in wild-type (WT) or mog1Δ strains relative to total H3. The bar graphs indicate the mean and standard deviation for at least three independent experiments. The significance of the differences was calculated using Student´s t-test (*, P value = 0.01-0.05; **, P value = 0.001-0.01; ***, P < 0.001)
