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

Researchers have identified 'Borgs', large extrachromosomal elements within "Candidatus Methanoperedens" archaea that enhance host metabolism in methane-rich environments. This study, through extensive genomic analysis and novel sequencing techniques, reveals Borgs' robust genetic frameworks, highlighting their significant role in biogeochemical processes, potentially influencing global methane cycles.
