Genome synteny plot of the “Firm-5” strains. Comparative analyses of the “Firm-5” genomes. The genome and plasmid sequences are represented by horizontal grey lines. The similarity between genomes was inferred with blastn and is shown with connecting grey lines, where darker lines indicate higher similarity. Blue bars show the positions of conserved group-specific core genes. Yellow bars indicate the positions of genes, which are strain-specific. The positions of the putative surface-exposed proteins are indicated in red. CRISPR genes are shown in purple. The tree topology is as in Figure 1.
