Figure. . . Phylogenetic relationship between DRV-TH11 isolate and orthoreovirus of the avian orthoreovirus (ARV) and mammalian orthoreovirus (MRV). ARV includes chicken reovirus, Muscovy duck reovirus, and Pekin duck reovirus. GenBank accession numbers of the sequences in the analysis are indicated in the tree. The neighbor-joining tree is based on the complete sequence of s2 gene (1,251 nt). Numbers at nodes represent the percentage of 1,000 bootstrap replicates (values <50 are not shown). Scale bar indicates a branch length corresponding to 100 character-state changes.
