Population Subdivision of Fusarium graminearum from Barley and WheatCorrelation between the type of toxin produced (chemotype) and population structure in Fusarium graminearum, the causal agent of head blight, is well established in wheat but not in barley. Using robust population genetic analyses of strains of Fusarium graminearum from barley and wheat, Liang et al. found that subdivision within the barley population corresponded with that of previously described wheat populations.
