Quantification of Outcrossing Events in Haploid Fungi Using Microsatellite Markers.

ABSTRACT: Species in genera of the fungal family Ceratocystidaceae are known to have different mating strategies, including heterothallism and homothallism. Of these, species of Ceratocystis, typified by the pathogen Ceratocystis fimbriata all undergo unidirectional mating-type switching. This implies that the pathogens possess the ability to self, but also to undergo sexual outcrossing between isolates of different mating types. In this study, we extended the recently developed microsatellite-based technique to determine the extent to which outcrossing occurs in ascospore masses of haploid fungi to two field collections of Ceratocystisalbifundus. In this way, the role of reproductive strategies in shaping population structure and diversity could be better understood. Results showed that a high freq
