Figure 2

Frequency, intensity and distribution of positively selected sites in the C2, V3 and C3 regions along the course of HIV-2 infection. Positively selected codons (obtained with Codeml, model M3) were classified in two categories according to the ω ratio:ω>6, codons under strong selective pressure; 1<ω<6, codons under weak selective pressure. The frequency and distribution of positively selected sites in the C2, V3 and C3 regions are shown in each infection year. Higher frequency positively selected sites are shown in bold letters. Sites were numbered according to the reference HIV-2ALI strain. (na, not available)
