Fig. 3. — Phylogenetic tree of 37–52 p17 fragment. The tree of fragment 37–52 p17 was obtained using the representative fragment for each cluster. (A) The HIV-1/SIVcpz and SIVgor, OWM SIV, and HIV-2/SIVsmm branches are highlighted in pink, yellow, and azure, respectively. (B) The cluster of SIVcpzPts (orange) with two SIVgsn (purple) is shown in area 1. SIVcpzPts here pointed out is the SIV closely related to HIV-1, between HIV1/SIVcpz-gor and OWM SIV/HIV2-SIVsmm branches. Color code: black, HIV1; red, SIVcpzPtt and SIVgor; orange, SIVcpzPts; fuchsia, SIVcol/wrc (colobus genus); purple, SIVgsn/mon/mus/asc/deb/lst/den/syk/blu/sol (cercopithecus genus); green, SIVsab/tan/ver/grv/mal (chlorocebus genus); brown, SIVmnd/drl (mandrillus genus); silver, SIVrcm/agi (cercocebus genus); olive, SIVtal; blue, SIVsmm; azure, HIV-2.
