Phylogeography of Japanese Encephalitis Virus: Genotype Is Associated with Climate
GI-V are represented to the right of the tree. Branch tips correspond to the date of collection of each of the virus isolates from which JEV sequence information was derived. Branch lengths correspond to lengths of time (in years), as measured by the scale underneath the tree. Terminal branches are colored according to the sampling location of the taxon at the tip, while internal braches are colored according to the most probable location of their child node. The branch colors correspond to those used in the map and legend. The numbers to the upper-left of the nodes correspond to the country phylogeographic analysis date presented in Table 2 and the numbers to the lower-left of the nodes are posterior probability values.
