Phylogenetic analysis of individual HIV-1 envelope gp120 proviral clones from macaques infected with SHIV-89.6P at 32 weeks postinfection. The maximum likelihood tree is rooted on the consensus of the inoculum. Sequences from each macaque are clustered together and uniformly colored. Branches were collapsed if the bootstrap value was below 50; bootstrap values over 50 are labeled on the tree.
