Fig. 7From: Combining manipulation of transcription factors and overexpression of the target genes to enhance lignocellulolytic enzyme production in Penicillium oxalicum Transcription analysis of lignocellulolytic enzymes in M12 and its engineered strains on wheat bran. Transcriptional levels of lignocellulolytic enzymes in RE-6, RE-7, and RE-8 strains versus those in wild-type strain (set to one) at 4 h (a) and 24 h (b) were analyzed. Error bars represent the standard deviations. Statistical significance of the differences between strains was calculated. *p < 0.05, **p < 0.01, ***p < 0.001Back to article page
