Neighbor-joining phylogenetic trees of PR and RT gene sequences. Phylogenetic trees were constructed for newly sequenced HIV-1 PR (A) and RT (B) genes along with the corresponding viral gene of reference HIV-1 strains, representing subtype A1, subtype A2, subtype B, subtype C, subtype D, subtype G, CRF01_AE, CRF02_AG, CRF15_01B and CRF33_01B. The reference strains of the HIV-1 subtype were shown in blue and bold. The sequence codes are presented as the GenBank accession number, patient ID or name of reference strain, and the subtype or CRF of reference strain (shown in parentheses) in order. DNA or RNA following the patient ID indicates the origin of the viral sequence, i.e., DNA extracted from PBMC or RNA extracted from a plasma sample, respectively. Bootstrap values are shown when the values are >70.
