Mating assays of T. reesei QM6a MAT1-2 with a mating type switched T. reesei QM6a MAT1-1 (left) and with a mating type switched T. reesei QM6a MAT1-1 which was additionally complemented with the functional ham5 allele of CBS999.97 (right). Due to the effect of female sterility no fruiting bodies are formed in the contact zone of a QM6a MAT1-2 strain with a mating type switched QM6a. After complementation with a functional ham5 allele the phenotype is altered, sporulation is reduced and fruiting bodies (indicated by black arrows) appear in the contact zone of the two strains
