From: RT-SHIV subpopulation dynamics in infected macaques during anti-HIV therapy
Phylogenetic analysis of RT-SHIV subpopulations of macaque M03250. The left panel is a neighbor-joining tree of all subpopulations of M03250. Each subpopulation is shown as a single sequence for this tree construction. Subpopulations from each week are represented by symbols coded with the same color and shape. The internal nodes from which subpopulation clusters containing drug resistant mutations appeared are marked as clusters A, B, C, D, and E, shown enlarged to the right.
