Analyses of virulence genes of clavibacter michiganensis subsp. Michiganensis strains reveal heterogeneity and deletions that correlate with pathogenicity

Clavibacter michiganensis subsp. michiganensis (Cmm) is the causal agent of bacterial canker of tomato. Differences in virulence between Cmm strains have been reported. The aim of this study was the characterization of nine Cmm strains isolated in Chile t
