Evolutionary network of the Rickettsia pan-chromosome displaying best homologues from the Rickettsia pan-plasmidome and customised databases containing non-Rickettsia protein sequences of bacteria, archaea, eukarya and viruses. Nodes correspond to the pan-chromosome cRiGs. Node colours correspond to the core (in blue) or flexible (in red) cRiGs. Node sizes refer to sequence identities (from 30 to 100%) between a cRiG and its first best homologue, which are linked by blue edges. * unclassified bacteria.
