Figure 4From: Newly recognized mosquito-associated viruses in mainland China, in the last two decadesPhylogenetic analysis based on the full coding sequences of Alphavirus isolated in China together with those referred in this review. Phylogenetic analyses were performed by the neighbor-joining method with MEGA software http://www.megasoftware.net/. Bootstrap probabilities of each node were calculated with 1,000 replicates. Scale bars indicate a genetic distance of 0.05-nt substitutions per site. The Chinese isolates are all shown in boldface in red.Back to article page
