FIG 1.

Maximum likelihood phylogenetic tree of rhabdoviruses based on inferred amino acid sequence of complete L gene ORFs (range of lengths 1874 to 2233 amino acids). Italicized taxa are recognized genera, with triangles proportional in depth to the maximum divergence within each genus. Colored shading indicates the three recognized rhabdovirus subfamilies, and gray shading indicates genera currently unassigned to subfamily. Viruses identified in freshwater mussels (KILLV-1 and CHMFV-1) are in bold type. Colored circles indicate host type(s) associated with each taxon. Ellipses are shaded in proportion to bootstrap values based on 1,000 replicates; only values ≥50% are shown. Scale bar indicates amino acid substitutions per site. Details of viruses and sequences are given in Table S1.
