Virulence is not directly related to strain success <i>in planta</i> in <i>Clavibacter nebraskensis</i>.

ABSTRACT: Goss's wilt and leaf blight of maize is an economically important disease caused by the Gram-positive bacterium, Clavibacter nebraskensis (Cn). Little is known about the ecology and pathogenesis of this bacterium. Here, we used phenotypic assays and a high-throughput whole-genome sequencing approach to explore among-strain variation in virulence and multistrain reproductive success in planta. Our survey of 41 strains revealed that more recently sampled strains tended to have higher virulence than strains sampled before 2010 and tended to be more genetically divergent from the reference strain, isolated in 1971. More detailed assays with a representative sample of 13 of these strains revealed that host genotype (resistant or susceptible) did not strongly affect strain s
