Recombination analysis. (A) The similarity between 08-28 and the reference sequence (05-24, 05-26, and D.CD.83ELI.K03454) was plotted using Simplot 3.5.1 software. The x-axis is the nucleotide position in the HIV-1 envelope genomic sequence. The y-axis shows the percentage supporting the clustering with different reference sequences. Subregion A, Subregion B, and Subregion C were indicated. (B) The neighbor-joining tree of Subregion A. Sequence 08-28 (nt 6427~7812) clustered with lineage b. (C) The neighbor-joining tree of Subregion B. Sequence 08-28 (nt 7816~8282) clustered with lineage c. (D) The neighbor-joining tree of Subregion C. Sequence 08-28 (nt 8333~8595) clustered with lineage c.
