Figure 2. Phylogenetic analysis based on the complete coding sequence of the 12th segment of Banna viruses (BAVs) currently isolated. Phylogenetic analyses were performed by the neighbor-joining method using MEGA version 4 software (www.megasoftware.net). Bootstrap probabilities of each node were calculated with 1,000 replicates. The tree was rooted by using Kadipiro virus and Liaoning virus as the outgroup viruses. Scale bars indicate a genetic distance of 0.1-nt substitutions per site. Isolates obtained in China are in boldface. Viruses were identified by using the nomenclature of virus strain/country/year of isolation/origin.
