Figure 3.
Maximum likelihood phylogenetic tree (A,C) and genome structure (B) of Smacoviridae and oyster-related viruses. The maximum likelihood phylogenetic tree was constructed using IQtree (version 2.1.4) based on the Rep amino acid sequences of Smacoviridae-like viruses. ModelFinder was set to MFP, and 1000 ultrafast bootstraps were used. Bootstrap values > 70 are shown. The color of the line corresponds to the color of the virus source shown. Extensive recombination can be inferred when replicase proteins are associated with coat proteins and with different types of structural proteins and vice versa. Genome structure was used for SnapGene (version 4.3.6).
