Résumé
We report the development of 44 microsatellite markers in three host races of the fungus Microbotryum violaceum, a sexually transmitted disease of the Caryophyllaceae. An enrichment protocol was used to isolate microsatellite loci from three strains, collected, respectively, from the plant species Gypsophila repens, Dianthus sylvestris, and Silene vulgaris. Polymorphism and cross-amplification were explored with 32 isolates of M violaceum , collected on 12 different plant species in natural populations.
