Fig 7. Evolutionary history of the ColE1 plasmids.

Fig 7

The schematic representation of the ColE1 ori is illustrated with two antisense black arrows for both the RNAI and RNAII, and the ColE1 relaxase with a thick grey arrow annotated as MOB. The divergent evolution of the ColE1 ori within Aeromonadales/Enterobacterales and Pasteurellales/Vibrionales, respectively, is represented with black arrows ending in two grey boxes, each of them showing three (SL1-3) or two stem loops (SL1-2). At the right of the figure, the genetic elements related to the ColE1 plasmids within each Order are represented. The rop gene in Enterobacterales is represented with a blue arrow; the repB gene in Aeromonadales with a purple arrow; and the dashed purple arrow below the repB gene represents its variable location within the plasmid.
