“…Therefore, these Bathyarchaeia lineages may already have specifically adapted to different terrestrial ecosystems, which expand the range of ecological impacts and significance of the class Bathyarchaeia from oceanic to terrestrial environments. Besides, only one MAG from the order Xuanwuarculales was recovered from the underground water sediment ( 27 ) (Fig. 2b), implying that more sampling efforts are needed to explore the potential novel Bathyarchaeia species inhabiting the deep terrestrial biosphere.…”

Bathyarchaeia, as one of the most abundant microorganisms on Earth, play vital roles in the global carbon cycle. However, our understanding of their origin, evolution and ecological functions remains poorly constrained. Based on the phylogeny of the present largest dataset of Bathyarchaeia metagenome assembled genome (MAG), we reclassified Bathyarchaeia into eight order-level units and corresponded to the former subgroup system. Highly diversified and versatile carbon metabolisms were discovered among different orders, particularly atypical C1 metabolic pathways, indicating that Bathyarchaeia represent overlooked important methylotrophs. Molecular dating results indicate that Bathyarchaeia diverged at ~3.3 Ga, followed by three major diversifications at ~3.0 Ga, ~2.5 Ga and ~1.8-1.7 Ga, likely driven by continental emergence, growth and intensive submarine volcanism, respectively. The lignin-degrading Bathyarchaeia clade emerged at ~300 Ma and perhaps contributed to the sharply decreased carbon sequestration rate during the Late Carboniferous period. The evolutionary pathway of Bathyarchaeia potentially have been shaped by geological forces, which in turn impacted the Earth's surface environment.

“…Gammaproteobacteria, Desulfobacterales, and Desulfobulbia occupied their ecological niches in upper sediments and may exhibit preference for alphatic/protein groups (see also references Teeling et al, 2012 ; Nikrad et al, 2014 ; Zhao Z. et al, 2019 ). Dehalococcoidia and Bathyarchaeia have been thought to be important for organic matter degradation in deep sediments ( Oni et al, 2015 ; Lazar et al, 2017 ; Vuillemin et al, 2020 ); Bathyarchaeia, in particular, were capable of lignin utilization in enrichment cultivation ( Yu et al, 2018 ) and significantly correlated with terrestrially derived organic matter in Pearl River estuary ( Wang P. et al, 2020 ). This is consistent with our observation that DOM molecules belonging to lignins/CRAM-like structures were correlated to Dehalococcoidia, Bathyarchaeia and other deep-sediment enrich groups like Planctomycetota and Desulfatiglanales ( Figure 5 and Supplementary Figure 4 ).…”

Dissolved organic matter (DOM) provides carbon substrates and energy sources for sediment microbes driving benthic biogeochemical processes. The interactions between microbes and DOM are dynamic and complex and require the understanding based on fine-scale microbial community and physicochemical profiling. In this study, we characterized the porewater DOM composition in a 300-cm sediment core from the Pearl River estuary, China, and examined the interactions between DOM and archaeal and bacterial communities. DOM composition were highly stratified and associated with changing microbial communities. Compared to bacteria, the amplicon sequence variants of archaea showed significant Pearson correlations (r ≥ 0.65, P < 0.01) with DOM molecules of low H/C ratios, high C number and double bond equivalents, indicating that the distribution of archaea was closely correlated to recalcitrant DOM while bacteria were associated with relatively labile compounds. This was supported by the presence of auxiliary enzyme families essential for lignin degradation and bcrABCD, UbiX genes for anaerobic aromatic reduction in metagenome-assembled genomes of Bathyarchaeia. Our study demonstrates that niche differentiation between benthic bacteria and archaea may have important consequences in carbon metabolism, particularly for the transformation of recalcitrant organic carbon that may be predominant in aged marine sediments.

Bathyarchaeia, as one of the most abundant microorganisms on Earth, play vital roles in the global carbon cycle. However, our understanding of their origin, evolution, and ecological functions remains poorly constrained. Here, we present the largest dataset of Bathyarchaeia metagenome assembled genome to date and reclassify Bathyarchaeia into eight order-level units corresponding to the former subgroup system. Highly diversified and versatile carbon metabolisms were found among different orders, particularly atypical C1 metabolic pathways, indicating that Bathyarchaeia represent overlooked important methylotrophs. Molecular dating results indicate that Bathyarchaeia diverged at ~3.3 billion years, followed by three major diversifications at ~3.0, ~2.5, and ~1.8 to 1.7 billion years, likely driven by continental emergence, growth, and intensive submarine volcanism, respectively. The lignin-degrading Bathyarchaeia clade emerged at ~300 million years perhaps contributed to the sharply decreased carbon sequestration rate during the Late Carboniferous period. The evolutionary history of Bathyarchaeia potentially has been shaped by geological forces, which, in turn, affected Earth’s surface environment.
