Abstract

Abstract: Clade 2 of the Fusarium solani species complex contains plant pathogens including Fusarium virguliforme and closely related species Fusarium brasiliense, Fusarium crassistipitatum, Fusarium tucumaniae, which are the primary causal agents of soybean sudden death syndrome (SDS), a significant threat to soybean production. In this study, we developed microsatellite markers from a F. virguliforme genome sequence and applied them to a F. virguliforme population collection of 38 isolates from Michigan and four reference strains from other locations. Of the 225 detected microsatellite loci, 108 loci were suitable for primer design, and 12 of the microsatellite markers were determined to be highly polymorphic, amplifying on average 5.7 alleles per locus. Using these markers, F. virguliforme isolates were partitioned into three distinct clusters, but isolates were not grouped based on relatedness of sampling sites. In addition, 11 out of 12 markers were demonstrated to be highly transferrable to other closely related species.
