Borg extrachromosomal elements of methane-oxidizing archaea have conserved and expressed genetic repertoires

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: June 26, 2024

Abstract Borgs are huge extrachromosomal elements (ECE) of anaerobic methane-consuming “ Candidatus Methanoperedens” archaea. Here, we used nanopore sequencing to validate published complete genomes curated from short reads and reconstruct new genomes. 13 four near-complete linear share 40 genes that define a largely syntenous genome backbone. We use these conserved identify peatland soil delineate Borg phylogeny, revealing two major clades. Remarkably, encoding nanowire-like electron-transferring cytochromes cell surface proteins more highly expressed than those host Methanoperedens , indicating augment the activity in situ. reconstructed first 4.00 Mbp for is inferred be predicted its methylation motifs, which differ pervasive TC CC motifs Borgs. Thus, may enable distinguish their Very high ratios structural predictions suggest capable encapsulation. The findings clearly as distinct class ECE with shared genomic signatures, establish diversification common ancestor genetic inheritance, raise possibility periodic existence outside cells.

Mechanisms of microbial co-aggregation in mixed anaerobic cultures

Applied Microbiology and Biotechnology, Journal Year: 2024, Volume and Issue: 108(1)

Published: July 4, 2024

Abstract Co-aggregation of anaerobic microorganisms into suspended microbial biofilms (aggregates) serves ecological and biotechnological functions. Tightly packed aggregates metabolically interdependent bacteria archaea play key roles in cycling carbon nitrogen. Additionally, applications, such as wastewater treatment, provide a complete metabolic network to convert complex organic material. Currently, experimental data explaining the mechanisms behind co-aggregation anoxic environments is scarce scattered across literature. To what extent does this process resemble aerobic environments? Does limited availability terminal electron acceptors drive mutualistic relationships, contrary commensal relationships observed oxygen-rich And do co-aggregating archaea, which depend on each other harvest bare minimum Gibbs energy from energy-poor substrates, use similar cellular those used by pathogenic that form biofilms? Here, we an overview current understanding why how mixed communities co-aggregate discuss potential future scientific advancements could improve study aggregates. Key points • Metabolic dependency promotes aggregation Flagella, pili, adhesins role formation Cyclic di-GMP/AMP signaling may trigger polysaccharides production anaerobes
