Fig. 1.

Phylogenetic and metabolic representation of assembled archaeal MAGs. Maximum-likelihood-based phylogenetic tree of up to 15 concatenated ribosomal proteins (rpL2, 3, 4, 5, 6, 14, 15, 18, 22, 24 and rpS3, 8, 10, 17, 19) from archaeal MAGs assembled from Guaymas Basin deep-sea sediments. MAGs were assembled from dive 4484 and 4572 (dark red). Only includes MAGs with ≥ 8 ribosomal proteins. Circles represent bootstrap values > 70% (bootstrap values were generated using the ultrafast bootstrap method with 1000 replications). Core metabolic processes: metabolic reconstruction was based on gene calling and annotation using IMG/MER, RAST, a custom blast and hmmer database search (see the “Methods” section). ¹The “Methanogenesis” identifier reflects the presence of mcrA and related genes identified as key components of methanogenesis and the oxidation of methane and butane through reverse methanogenesis (Additional file 1: Table S4)
