ARA1 regulates not only L-arabinose but also D-galactose catabolism in Trichoderma reesei


ABSTRACT: Trichoderma reesei is used to produce saccharifying enzyme cocktails for biofuels. There is limited understanding of the transcription factors (TFs) that regulate the release and catabolism of L-arabinose and D-galactose, as the main TF XYR1 is only partially involved. The T. reesei ortholog of ARA1 from Pyricularia oryzae that regulates L-arabinose release and catabolism, was deleted and characterized by growth profiling and transcriptomics along with a xyr1 mutant and xyr1/ara1 double mutant. Our results show that, in addition to the L-arabinose-related role, T. reesei ARA1 is essential for D-galactose release and catabolism, while XYR1 is not involved in this process.
