Extended Data Fig. 7: Maximum likelihood phylogeny of AcrIII-1 homologues.
From: An anti-CRISPR viral ring nuclease subverts type III CRISPR immunity
The maximum likelihood phylogenetic tree was constructed with automatic selection of the best-fit substitution model for a given alignment (LG + G + I). Red circles indicate 95–100% branch support, as assessed using aBayes implemented in PhyML. The scale bar represents the number of substitutions per site. Branches and labels are colour coded: red, archaea; black, bacteria; blue, bacteria and archaea in which AcrIII-1 homologues are associated with CRISPR loci; green, archaeal viruses and plasmids; orange, bacteriophages.
