Evolutionary rates (ER) throughout the HIV genome within- and between-hosts. A) HIV genome, B) Median evolutionary rates for the pooled WH data (in red) and BH data (in black) and C) Median evolutionary rates for all the datasets. In panel B, shaded boxes indicate 50% credibility intervals. The thick line shows the C2V5 region (studied by former studies) and the dashed line the ENV1 segment. The env gene is highlighted in yellow. In panel C, the colour code is red for PIC1362, green for PIC38417, blue for PIC71101, cyan for PIC83747, purple for PIC90770 and black for the BH data (UP-up4).
