Neighbor-joining tree. The top thirteen hits of a nucleotide BLAST search using the coding sequence of tlp12 of strain A17 as a query were aligned with the tlp12 sequence of strain A17 together with the reference sequences for tlp2, tlp3, tlp4, tlp11 and tlp13. Global alignment with free end gaps was used. A neighbor-joining tree was constructed using the Geneious 10.0.9 software. The tlp12 CDS of strainA17 is indicated by an arrow, the tlp12 CDS of strain R14 is indicated by an asterisk
