Genome synteny plot of the “Firm-4″ strains. Comparative analysis of the “Firm-4” 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 not shared between the two strains. Red bars indicate the conserved group-specific operon encoding the putative cscAB genes , whereas green bars show the position of putative eps-clusters.
