Transcriptional levels of cel7a in the parent strain and fTF-containing transformants. a Cultivation for 1 h; b cultivation for 6 h; c cultivation for 8 h; d cultivation for 12 h. The transcriptional level of the cel7a gene was normalized to that of actin (data presented are mean ± SEM; *p < 0.05, **p < 0.01, ***p < 0.001, n = 3; two-tailed Student’s t tests)
