FIG. 4.

Inference of PTLV-3 phylogeny using 589 bp tax-pX-LTR sequences. Numbers correspond to internal branch support derived from 100 bootstrap replications (only values above 85 are shown). Scale bar represents the number of nucleotide substitutions per site. Primate taxonomy nomenclature is according to Groves (Groves, 2001). Nonhuman primates are coded using the first letter of the genus followed by the first two letters of the species name: Lal, Lophocebus albigena; Cag, Cercocebus agilis; Cce, Cercopithecus cephus. Sequences in italic and bold text are from the current study.²⁵
