520 _aSimple sequence repeats (SSR) markers were developed from a small insert genomic library for Bipolaris sorokiniana, a mitosporic fungal pathogen that causes spot blotch and root rot in switchgrass. About 59% of sequenced clones (n = 384) harbored SSR motifs. After eliminating redundant sequences, 196 SSR loci were identified, of which 84.7% were dinucleotide repeats and 9.7% and 5.6% were tri- and tetra-nucleotide repeats, respectively. Primer pairs were designed for 105 loci and 85 successfully amplified loci. Sixteen polymorphic loci were characterized with 15 B. sorokiniana isolates obtained from infected switchgrass plant materials collected from five states in USA. These loci successfully cross-amplified isolates from at least one related species, including Bipolaris oryzae, Bipolaris spicifera and Bipolaris victoriae, that causes leaf spot on switchgrass. Haploid gene diversity per locus across all isolates studied varied 0.633?0.861. Principal component analysis of SSR data clustered isolates according to their respective species. These SSR markers will be a valuable tool for genetic variability and population studies of B. sorokiniana and related species that are pathogenic on switchgrass and other host plants. In addition, these markers are potential diagnostic tools for species in the genus Bipolaris.
