摘      要：Metagenomic explorations of the Earth s biosphere enable the discovery of previously unknown bacterial lineages of phylogenetic and ecological ***,we retrieved 11 metagenomic-assembled genomes(MAGs)affiliated to three new monophyletic bacterial lineages from the seawater of the Yap *** analysis revealed that each lineage is a new bacterial candidate phylum,subsequently named Candidatus Qinglongiota,Candidatus Heilongiota,and Candidatus *** reconstruction of genomes from the three phyla suggested that they adopt a versatile lifestyle,with the potential to utilize various types of sugars,proteins,and/or short-chain fatty acids through anaerobic *** was further confirmed by a global distribution map of the three phyla,indicating a preference for oxygen-limited or particle-attached niches,such as anoxic sedimentary *** note,Candidatus Canglongiota genomes harbor genes for the complete WoodLjungdahl pathway and sulfate reduction that are similar to those identified in some sulfate-reducing *** analysis indicated that gene gain and loss events,and horizontal gene transfer(HGT)play important roles in shaping the genomic and metabolic features of the three new *** study presents the genomic insight into the ecology,metabolism,and evolution of three new phyla,which broadens the phylum-level diversity within the domain Bacteria.
