Phylogenetic analysis of PTLV-1 LTR sequences. a Maximum likelihood (ML) tree inferred using 207 HTLV-1 and STLV-1 taxa and an LTR alignment of 732 positions. Node support determined using 1000 nonparametric bootstraps. Only bootstrap values >60 are shown. b Bayesian-inferred tree using a subset of LTR sequences identified from the ML analysis as having high genetic identify to HTLV-1NIH00261 and using selected West African, cosmopolitan, and Australomelanesian reference HTLV-1s for a total of 29 taxa. Posterior probabilities ≥0.7 are shown at nodes. Scale bar is in unit of time relative to the mean substitution rate used for the analysis. HTLV-1NIH00261 is shown in green text and with a green arrow. HTLV-1 from three Africans infected with STLV-1 from sooty mangabey monkeys are shown in blue text
