Fig. 3: Phylogeny, relative abundances and transcriptional activities of putative chemolithoautotrophic MAGs.
From: Carbon fixation rates in groundwater similar to those in oligotrophic marine systems
Approximately maximum-likelihood phylogenetic tree based on concatenated single-copy protein alignments for all bacterial MAGs considered. Branches are coloured according to the predicted carbon fixation pathway, and the matching leaf is indicated by a point. Bar charts present average normalized metagenomic coverages within each well from triplicate 0.2 μm filtered fractions. Pie charts show the coverage of mRNA transcripts recruited, normalized to gene number and library size. Asterisks denote MAGs discussed in greater detail in Supplementary Information. The tree is rooted using Patescibacteria (CPR) as an outgroup, indicated by the collapsed grey leaf in the upper left. Node numbers: (1) c_Nitrospiria, (2) c_Thermodesulfovibrionia, (3) o_Nitrospirales, (4) f_Nitrospiraceae, (5) g_Nitrospira_D, (6) g_Nitrospira, (7) p_Nitrospinota, (8) c_Gammaproteobacteria, (9) o_Acidiferrobacterales, (10) f_Sulfurifustaceae, (11) g_SM1-46, (12) f_UBA6901, (13) o_Burkholderiales, (14) f_Nitrosomonadaceae, (15) g_Nitrosomonas, (16) f_SG8-41, (17) f_SG8-39, (18) c_Brocadiae, (19) o_Brocadiales, (20) f_Brocadiaceae and (21) f_Scalinduaceae.
