Phylogeny of arsenite efflux pumps in RefSoil+ organisms. Maximum likelihood tree with 100 bootstrap replications of a Acr3 and b ArsB sequences predicted from RefSoil+ genomes. Tree scale = 1. Leaf tip color indicates phylum-level taxonomy. Bootstrap values > 50 are represented by black circles within the tree. Gray circles on the exterior of the tree indicate that a hit was detected on a plasmid and not a chromosome
