Figure 1.

Neighbor-joining phylogenetic trees based on protein-coding sequences of A) small, B) medium, and C) large partial RNA segments for Simbu serogroup viruses, southern Japan, 2015–2016. Black circles indicate Shamonda viruses isolated in this study. Values along branches are percentages (≥50%) of bootstrap support of 1,000 pseudoreplicates. The 3 segmented RNAs of Bunyamwera virus were used as outgroups to root the trees. Scale bars indicate nucleotide substitutions per site. NA, details not available.
