Isolation and characterization of microsatellite markers from the entomopathogenic fungus Metarhizium anisopliae

Fourteen polymorphic microsatellite markers were isolated from the entomopathogenic fungus, Metarhizium anisopliae, based on enriched genomic libraries. In order to assess allelic variability, the microsatellite loci were analysed in a collection of 34 isolates sampled from across Switzerland. The number of detected alleles in 14 loci ranged from two to eight and expected heterozygosity from 0.265 to 0.808. Because of the high expected heterozygosity, the 14 microsatellite loci are very useful for ecological studies and analysis of population diversity, and to identifying, monitoring, and tracking M. anisopliae strains applied as biological control agents.
