Fig 2. Eukaryotic RdRP phylogeny supports the vertical transfer scenario.
A. Bayesian phylogenetic tree of the eukaryotic RdRP family. α, β and γ clades of eukaryotic RdRPs have been defined by [31]. Sectors highlighted in grey are detailed in panels B, C and D for clarity. Scale bar: 0.4 amino acid substitution per position. Posterior probability values are indicated for each node in panels B–D.
