Fig. 2: Phylogenomic trees of bacteria (1367 SAGs) and archaea (7 SAGs) of Subglacial Lake Mercer.
From: Genetic isolation and metabolic complexity of an Antarctic subglacial microbiome
Two maximum likelihood trees were reconstructed using RAxML from the concatenated GTDB protein sequence alignment (5035 aligned sites) of 120 bacterial marker genes and from that (10,100 aligned sites) of 53 archaeal marker genes, respectively. The bacterial tree was rooted by the most recent common ancestral node of Patescibacteria. The archaeal tree is unrooted. From the innermost to the outmost, colors indicate the most abundant genera, phyla, the depth of sediment, and microbial cell sizes of the water column, respectively. Bootstrap support values were indicated on the nodes using black, grey, and open circles. An asterisk indicates the unclassified genus Burkholderaceae incertae sedis. Source data are provided as a Source Data file.
