From: Isolation and molecular characterization of genotype 1 Japanese encephalitis virus, SX09S-01, from pigs in China

Figure 4

Phylogentic tree was constructed by the neighbour-joining method based on the E genes of JEV strains mostly selected from different geographic regions in China at different time periods, where available in Genbank listed in additional file 1. Phylogenetic groupings corresponding to the genotyping classification are indicated from GI to GV. Newly isolated strain is indicated with black triangle marker. The scale at the bottom of the tree indicates the number of nucleotide substitutions per site. Murray Valley encephalitis virus (MEV) was used as an outgroup.
