Molecular phylogenetic analyzed by the maximum-likelihood method. A maximum likelihood phylogenetic tree of Banna virus (BAV), KDV and Liao ning virus (LNV) was inferred based on the amino acid sequences of the first segments. BAV, LNV and KDV are labeled in red, green and blue, respectively. The newly discovered KDV strain is labeled with a solid circle. Numbers associated with branches indicate the percentage of 1000 bootstrap replicates that support the existence of these branches. Branches with < 60% bootstrap support have been collapsed
