PROCESS FOR PREPARING FILAMENTOUS FUNGAL STRAINS HAVING A SEXUAL CYCLE AND A PROCESS FOR PREPARING SEXUALLY CROSSED FILAMENTOUS FUNGAL STRAINS

摘要

The invention relates to a process for preparing filamentous fungal strains having a sexual cycle, wherein an acceptor filamentous fungal strain, having no or one type MAT locus, is subjected to recombination in which one or more mating type locus genes and optionally sex related genes, from other species than the acceptor filamentous fungal strain, is introduced into the acceptor filamentous fungal strain to produce a filamentous fungal strain having a sexual cycle.
