Phylogenetic relationships of likely vertebrate-associated viruses discovered from assembled contigs: (a) Hepeviridae, (b) Picobirnaviridae, (c) Astroviridae, and (d) Picornaviridae. The maximum-likelihood phylogenetic trees show the topological position of the newly discovered potential viruses (bold, red text), in the context of their closest relatives. All branches are scaled to the number of amino acid substitutions per site and trees were mid-point rooted for clarity only. An asterisk indicates node support of >70 per cent bootstrap support.
