Fig. 1From: Global molecular evolution and phylogeographic analysis of barley yellow dwarf virus based on the cp and mp genesTime-scaled maximum clade credibility tree of barley yellow dwarf virus inferred from the coat protein (A) and movement protein (B). The tree topologies have been chosen to maximize the product of node posterior probabilities. Branch lengths are scaled according to time, as shown by the horizontal axis. Branch colours denote inferred regions. The root state posterior probabilities of the geographic regions are shown in each inset panelBack to article page
