(Meta)Genomic Analysis Reveals Diverse Energy Conservation Strategies Employed by Globally Distributed Gemmatimonadota.

ABSTRACT: Gemmatimonadota is a phylum-level lineage distributed widely but rarely reported. Only six representatives of Gemmatimonadota have so far been isolated and cultured in laboratory. The physiology, ecology, and evolutionary history of this phylum remain unknown. The 16S rRNA gene survey of our salt lake and deep-sea sediments, and Earth Microbiome Project (EMP) samples, reveals that Gemmatimonadota exist in diverse environments globally. In this study, we retrieved 17 metagenome-assembled genomes (MAGs) from salt lake sediments (12 MAGs) and deep-sea sediments (5 MAGs). Analysis of these MAGs and the nonredundant MAGs or genomes from public databases reveals Gemmatimonadota can degrade various complex organic substrates, and mainly employ heterotrophic pathways (e
