Sexual development in the industrial workhorse Trichoderma reesei.

ABSTRACT: Filamentous fungi are indispensable biotechnological tools for the production of organic chemicals, enzymes, and antibiotics. Most of the strains used for industrial applications have been--and still are--screened and improved by classical mutagenesis. Sexual crossing approaches would yield considerable advantages for research and industrial strain improvement, but interestingly, industrially applied filamentous fungal species have so far been considered to be largely asexual. This is also true for the ascomycete Trichoderma reesei (anamorph of Hypocrea jecorina), which is used for production of cellulolytic and hemicellulolytic enzymes. In this study, we report that T. reesei QM6a has a MAT1-2 mating type locus, and the identification of its respective mating type counterpart, MAT1-1, in
