FIG. 3.

Bayesian-inferred rooted phylogeny of the PP1ab polyprotein. Two conserved regions of the polyprotein, homologous to sequences found in the gill-associated okavirus, were concatenated and edited to eliminate gaps and ambiguously aligned regions. A phylogeny was generated on the resulting 880-aa alignment as described in the legend to Fig. 1. The tree was rooted on the gill-associated okavirus, a member of the Roniviridae, which is a sister family to the Coronaviridae. Branch confidence values are given as PPs.
