From: Molecular epidemiology of Japanese encephalitis virus circulating in South Korea, 1983-2005
Maximum likelihood tree of 51 JEV strains representing four different genotypes, including 22 Korean strains. The HKY85 evolutionary model of nucleotide substitution was used to construct a ML tree for the complete E gene sequence. The tree was rooted with the E gene sequence of the Murray Valley encephalitis virus (MVEV, accession no. NC_000943). Branch reliability is indicated with quartet puzzling (QP) values. Branches showing QP reliability > 70% can be considered well supported [22]. The scale bar indicates the number of base substitutions per site. Korean strains are indicated as closed circles and the JEV genotypes are as defined previously [8].
