Mating-type heterokaryosis and selfing in Cryphonectria parasitica.

Fungal genetics and biology : FG & B - 1 May 2004

McGuire I Cristina, Marra Robert E, Milgroom Michael G

Abstract excerpt

Selfing in the chestnut blight fungus, Cryphonectria parasitica, occurs by two different genetic mechanisms. Most self-fertile isolates of C. parasitica are heterokaryotic for mating type, and the progeny from selfing segregate for mating type. Further, we resolved mating-type (MAT) heterokaryons into homokaryons of both mating types by isolating uninucleate asexual spores (conidia). However, because ascospore...
