Carbon catabolite repression (CCR), which is mainly mediated by Cre1 and triggered by glucose, leads to a decrease in cellulase production in <i>Trichoderma reesei</i>. Many studies have focused on modifying Cre1 for alleviating CCR. Based on the homologous alignment of CreA from wild-type <i>Penicillium oxalicum</i> 114-2 (Po-0) and cellulase hyperproducer JUA10-1(Po-1), we constructed a C-terminus substitution strain-Po-2-with decreased transcriptional levels of cellulase and enhanced CCR.
