HIV-1 CRF02_AG Maximum likelihood (ML) trees. The ML tree includes HIV-1 Moroccan CRF02_AG sequences, for which we have RT and PR sequences, together with 28 CRF02_AG strains downloaded from the HIV databases for which the full genome sequences were available. The tree was generated using the GTR+G model of nucleotide substitution using the concatenated RT and PR genes. Branches are drawn in scale, according to the bar at the bottom, and colored to reflect geographic origin according to the legend of the figure. The number along a branch indicates significant bootstrap support (> 65%). Sequences were named using the year of sampling preceded by the two letter county code of origin, according to the HIV database guidelines.
