Phylogenetic relationships of SIVcpz Ptt -Cam155 V1V4 env clones. Analyses were performed using a codon nucleotide alignment of 648 bp, once the gaps discarded, of the ten clones of SIVcpzPtt-Cam155 from 2004 and the ten ones from 2009 with previously published HIV-1/SIVcpz/SIVgor sequences. Phylogenetic analyses were run with both PhyML and Mr Bayes. Here presented in black and above the branches, the bootstraps > 0.70, and the grey stars below the branches are posterior probabilities > 0.80. Scale bars represent 0.1 replacements per site. On the right side is a zoom of the clones' phylogenetic relationships. The clone names 040 to 049 and 090 to 099 stand for SIVcpzPtt-Cam155 clones from 2004 and 2009, respectively, indicated by 04 and 09 followed by the clone number.
