Figure 1

Phylogenetic trees of HIV-1 pol genes were constructed using MEGA 5 based on neighbour-joining methods. The samples’ sequences and reference HIV-1 subtypes (subtypes A–D, F–H, J, K, CRF01_AE, CRF07_BC, CRF08_BC, and group O) available in the Los Alamos database were aligned using CLUSTAL W with minor manual adjustments. The statistical robustness of the neighbour-joining tree and reliability of the branching patterns were confirmed by bootstrapping (1000 replicates). The trees were midpoint rooted. Values on the branches represent the percentage of 500 bootstrap replicates.
