McrA gene phylogeny and genome tree phylogeny. Maximum-likelihood trees of a McrA proteins, and b a concatenated alignment of 122 single copy archaeal marker genes from high quality archaeal RefSeq genomes (release 80). Hydrogenotrophic and acetoclastic methanogens are shaded blue, H2-dependent methylotrophic methanogens are shaded green, known/putative methane oxidizers are shaded yellow, and lineages encoding divergent McrAs are shaded red. Bootstrap support was generated from 100 replicates, and white, gray and black nodes represent ≥50%, ≥75%, and ≥90% support, respectively
