Cover Story: Plasmids are mobile DNA elements actively exchanged among microorganisms. As mobile elements, they can carry genes associated with the production of secondary metabolites that enhance fitness and survival of the microbes acquiring them. The presence of plasmid-borne biosynthetic gene clusters of secondary metabolites was investigated in prokaryotic metagenome-assembled genomes (MAGs) from the geochemically stratified water column of the Cariaco Basin off Venezuela’s coast. Acquired and integrated terpene-biosynthetic genes and genes for the production of ribosomal and non-ribosomal peptides were found in archaeal and bacterial MAGs. While this mode of horizontal gene transfer may promote the cosmopolitan distribution of the taxa acquiring them, their ecological and evolutionary significance in oxygen-depleted water columns remains largely unexplored. View this paper
