Phylogram of codon-aligned nucleotide sequences for selected PFam32 orthologs from different Borrelia replicons. Genes from the RF species large plasmids (squares) and LD species lp54 plasmids (circles) are indicated. The replicons and accession numbers used for each species and strain are provided in Materials and Methods. Nodes with bootstrap values of >70% support by neighbor-joining distance criteria from 10,000 replicates are indicated. The scale bar represents nucleotide substitutions per site.
