Genetic analyses of the DENV panel (n=47). (A) Phylogenetic tree showing the evolutionary relationships of DENV E gene sequences. Sequences were aligned with MAFFT, and a maximum likelihood tree (ML) was estimated using a general time reversible model, accounting for both among site rate variation and invariant sites (GTR+G4+I). Bootstrap support values of at least 75% are shown. (B) Amino acid map of dengue E protein sequences (493-495 amino acids in length). The total amino acid differences between pairs of E sequences correspond to distances between points on the geometric display.
