Comparative analysis of Pacearchaeota-affiliated genomes from various habitats. On the left, a maximum likelihood phylogenetic tree of Pacearchaeota MAGs from this study (Idc_in_care_mg3 and Idc_in_meta_mg8) and from public databases was constructed using 122 archaeal marker genes with three Woesearchaeota MAGs (not shown in the phylogenetic tree) as an outgroup (GW2011-AR15: GCA_000830295.1; GW2011-AR11:GCA_013330825.1; GW2011-AR9: GCA_013331635.1). The best fit model was selected as K2P + I + G4. On the right, an overview of the presence or absence of metabolic genes commonly found in Pacearchaeota MAGs is shown. Gene annotation was performed using BlastKOALA with default thresholds (see methods).
