Placement of nine MAGs described in this study in the reference phylogeny of Archaea. NM2 was not included due to low completeness. Bayesian phylogeny (PhyloBayes, CAT+GTR+ Γ4) based on concatenation of 40 conserved phylogenetic markers (8,564 amino acid positions) and 156 genomes/MAGs (see Supplementary Table 5 and Supplementary Table 6 for detail). Node supports refer to posterior probabilities, and for reasons of readability only values above 0.8 are shown. The tree is rooted according to Raymann et al.52. The scale bar represents the average number of substitutions per site. Black arrows point to the 9 obtained MAGs and accolated pie charts indicate their estimated completeness. Colors indicate that genomes of these lineages encode an MCR/MCR-like complex, Class I/II methanogens are in green, methyl-dependent hydrogenotrophic lineages are in red, methanotrophs are in orange (some being within Class II), potential or validated shot-chain alkane users are in in blue. NM1 could also have a methane metabolism (see text for discussion).
