Fig 2. Positively selected genes as well as positively selected genes with previously identified recombination event that were identified within particular subspecies.
Genes identified as recombinant in a particular treponemal subspecies are shown in bold. Positively selected genes with no evidence of recombination are shown in regular version. Positively selected genes identified between subspecies of treponemes, but not within any of them, are not shown. Note that positively selected genes occur mostly within the TPA and the recombinant genes are within the TEN genomes. The TP0548 and TP0865 genes were found to be positively selected within TPA and also within TPE subspecies.
