Analysis of EACMV-like component re-assortments. Analysis of component re-assortment through counts of DNA-B component “migrations” between the DNA-A sequences of the major CMG lineages. In the analysis DNA-A sequences were classified into six discrete groups. Branches are coloured according to which of these six groups the DNA-B sequence represented by the node to their right was associated with. Black circled nodes indicate ancestral DNA-B sequences where there is less than a < 0.5 state probability for all six of DNA-A lineages (i.e. it is particularly uncertain which DNA-A these ancestral DNA-B sequences were associated with). Whereas filled circles associated with nodes to the right of branches indicate > 95% posterior probability support for these branches, open circles indicate branches with > 70% posterior support. Nodes to the right of branches with < 70% support are left unlabelled. DNA-B “migrations” between different DNA-A lineages that could be explained by genome re-assortment events inferred in an independent RDP3 analysis are indicated by the corresponding RDP3 event number listed in Table 2. The underlined event number (event 6) corresponds to a partial DNA-B”migration” that likely involved overprinting of part of the DNA-B CR with that of the DNA-A sequence that captured it.
