FIG 1.

Phylogenetic trees of the near-full-length HIV-1 variants isolated from the replication-competent reservoir of each patient. Maximum-likelihood phylogeny relating within-host near-full-length HIV sequences. Trees were built according to a maximum-likelihood approach using PhyML software. All the trees are represented at the same size in order to facilitate reading of the figure. Bar, 0.004 (all trees). Clusters of identical viral isolates (sequences diverging for less than 4 nucleotides) are indicated by geometric symbols.
