Fig 6. Linkage map of detected pil and opa recombination events.

Geneconv was used to detect statistically significant evidence (p < 0.05) for gene conversion events between the pil and opa genes of Gc and Mc [56]. Statistically significant gene conversion fragments were further parsed to remove any implied recombination events that occurred entirely within constant regions of the genes. Chromosomes of Mc are shown in blue while chromosomes of Gc are shown in red, all chromosomes are denoted by the strains of Mc or Gc they represent. Any scaffold chromosomes (assembled as contigs) are shown as thin grey lines inset to the chromosomes they represent. opa are shown as either green (sense) or yellow (antisense) bars relative to their locations on the chromosome. pil are shown inset to opa as either green (sense) or yellow (antisense) bars relative to their locations on the chromosome. Statistically significant gene conversion events are displayed as lines connecting either opa (purple) or pil (black) genes.
