Regulation of gene expression by PoxClrB, POX02484, and POX08522. Under induction by the same carbon source, the expression levels of genes encoding three cellobiohydrolases, eight endo-glucanases, three β-glucosidases and four xylanases were determined in the ΔPOX02484-6 (a), ΔPOX08522-2 (b) and ΔPoxClrB-1 (c) mutants at three different time points after the shift (4, 12 and 24 h) by qRT-PCR. Expression levels were normalized against the ΔPoxKu70 parent strain. The symbols * and ** indicate significant differences (P ≤ 0.05 and P ≤ 0.01, respectively) between the tested samples and the ΔPoxKu70 strain, as assessed by Student’s t test
