Microsatellite markers for <i>Sclerotinia subarctica</i> nom. prov.<i>,</i> a new vegetable pathogen of the High North

Abstract Eight polymorphic microsatellite loci were isolated from the ascomycete fungus Sclerotinia subarctica nom. prov. In Alaska, this pathogen causes white mold vegetable diseases sympatrically with the cosmopolitan and closely related Sclerotinia sclerotiorum . Eighteen alleles were observed across the 41 isolates tested and ranged from two to three alleles per locus. Together, the alleles from the eight polymorphic loci yielded only four haploid multilocus genotypes and exhibited significant linkage disequilibrium, reflecting extreme selfing and clonal vegetative reproduction.
