Mating type (MAT)-specific fragments of the two idiomorphs ofGibberella fujikuroi (anamorph,Fusarium moniliforme) were obtained by PCR amplification using primers to conserved regions ofMAT homologs from other fungal species and used to assign mating type by molecular criteria rather than the arbitrary historical designation. Mating type—strains of mating populations A-E and a mating type+strain of mating population F carry an α-box motif and should therefore be designatedMAT-1. Mating type+strains of mating populations A-E and a mating type—strain of mating population F carry an HMG-box motif and should be designatedMAT-2. Thus, assessment of mating type ofG. fujikurol strains can be easily achieved usingMAT-specific primers.
