Fig. 2 — ML phylogenetic tree of env sequences from HIV-1 controllers and HIV-1 subtype reference sequences. Branches were colored according to the subtype assignment as shown in the legend at bottom left. The individual’s identification is displayed on the right side of the clusters. Sequence clusters from dual infected individuals (EEC09, VC06 and VC32) are indicated by shaded boxes. Bootstrap support for each individual cluster is shown. Black circles point to the reference sequences and asterisks highlight the sequences with APOBEC3G-mediated G to A hypermutations. Horizontal branch lengths are proportional to the bar at the bottom indicating nucleotide substitutions per site
