Genetic diversity of Fusarium oxysporum f. sp. vasinfectum, using genotyping-by-sequencing

Fusarium oxysporum f. sp. vasinfectum (FOV) recently caused devastating outbreaks of Fusarium wilt of cotton in the southeastern United States. FOV is often characterized into nominal races and genotypes based on sequences at the translation elongation factor (EF-1a) locus, but the pathogen's genetic diversity isn't well characterized beyond these housekeeping genes. We used genotyping-by-sequencing (GBS) to identify SNPs and determine genetic structure and population diversity among 168 diverse Fusarium oxysporum isolates.
