Comparison of transcript levels of main cellulase, xylanase, transcription factor genes in DBD_cre1-VP16 transformants. Gene expression ratios (-fold) in DBD_cre1-VP16 transformants relative to RUT C30 on 2% glucose for 48 and 60 h. Gene expression ratios (-fold) were normalized to the corresponding gene expression at the same timepoint in the parental strain RUT C30. Values represent the mean of three biological replicates and error bars show the standard deviation; asterisks indicate significant differences (gene expression ratio greater than twofold or less than 0.5-fold between the transformants and the parental strain RUT C30)
