Fig 6. Genotyping analyses of complete gene sequences of DENV-4 serotype isolates (n = 3) from Pune.

Each strain is indicated by Genbank accession number followed by country and year of isolation. 141 Genotype II sequences obtained from Genbank are shown here as compressed tree (S1 Text provides the accession numbers). Numbers at the nodes are support values for the major branches (bootstrap; 1000 replicates). The sequences obtained in this study are marked in filled colored circles. Scale bar indicates number of base substitutions per site.
