FIG 4.

(Left) Phylogenetic relationships of the viruses within the order Tymovirales. ML phylogenetic tree based on the replication protein shows the topological position of virus-like sequences discovered in this study (black circles) in the context of their closest relatives. See Fig. 3 for the color scheme. All branches are scaled to the number of amino acid substitutions per site, and trees were midpoint rooted for clarity only. An asterisk indicates node support of >70% bootstrap support. Tip labels are bolded when the genome structure is shown on the right. (Right) Genomic organization of the virus sequences identified in this study and representative species used in the phylogeny.
