Microsatellite markers for the fungal banana pathogens, Mycosphaerella fijiensis, Mycosphaerella musicola and Mycosphaerella eumusae

We developed a total of 50 microsatellite markers for the three fungal pathogens causing the most important leaf spot diseases of banana: 32 loci for Mycosphaerella fijiensis are presented, and nine loci each for Mycosphaerella musicola and Mycosphaerella eumusae. All these loci were polymorphic within each species on a sample of isolates collected from various locations around the world. Within M. fijiensis and M. musicola, most of the loci tested (> 80%) in a sample of isolates from a single location in Cameroon were also polymorphic. Multiplex polymerase chain reaction systems were developed with 15 loci for M. fijiensis. (Résumé d'auteur
