Figure S1. Phylogenetic trees were constructed for the coding regions of BTV a) VP1 protein (segment-1), b) VP3 protein (segment-3, c) NS1 protein (segment-5), d) VP5 protein (segment-6), and e) NS2 protein (segment-8). Maximum likelihood trees were constructed using IQ-Tree software [23] and the reliability of each tree was estimated by ultrafast bootstrap [24] analysis of 1000 replicates (bootstrap values of < 95% are not displayed).
