Abstract excerpt
In fungi, stable diploid genome arrangements are rare. Here we present evidence from nuclear intergenic DNA sequencing, microsatellite genotyping, and configuration of the mating-type locus to demonstrate two independent origins of persistent diploid genome organization in the Metarhizium majus species complex. Most taxa in the complex are genotypically haploid, with individual isolates consistently displaying a...
