Fig 3. dnaA color-coded demarcation matrix of Clavibacter michiganensis subspecies.

Maximum likelihood (ML) phylogeny of 43 partial sequences within C. michiganensis subspecies were used for constructing the pairwise similarity scores, displaying a color-coded matrix. dnaA phylogeny within C. michiganensis shows evolutionary distances gathering nine evident clades, each one representing one subspecies. Bootstrap values were computed with 1,000 replicates using MEGA 7.0.25 and dnaA sequences of Leifsonia xyli and Rathayibacter tritici served as outgroup, sharing less than 89% similarity.
