Fig. 1

Overall sequence identity of the 15 sequenced strains with the reference M129 genome. BLAST-based similarity of a given strain versus the M129 reference is represented as a colored ring. Colors by strain are indicated to the right. Solid coloration indicates >99 % identity and transparent grey indicates approximately 95 % identity. Location in the reference genome is indicated by numeration on the inside of the ring. GC content in the reference genome is indicated by the black bar graphs between the genomic coordinates and the colored rings (bars pointing toward the outside of the circle indicate high GC content). Note that genomic structural alterations are not visible using this method
