Metagenome sequencing and 107 microbial genomes from seamount sediments along the Yap and Mariana trenches.

ABSTRACT: Microbes in the sediments across a series of seamounts along the island arc of the Yap and Mariana trenches were investigated by metagenome. In this study, we reconstructed 107 metagenome-assembled genomes (MAGs), including 100 bacteria and 7 archaea. All the MAGs exhibited >75% completeness and <10% contamination, with 26 MAGs being classified as 'nearly complete' (completeness >90%), while 50 falling within 80-90% range and 31 between 75-80% complete. Phylogenomic analysis revealed that 86% (n = 92) of these MAGs represented new taxa at different taxonomical levels. The species composition of these MAGs was most consistent with the previous reports, with the most abundant phyla being Proteobacteria (n = 39), Methylomirabilota (n = 27), and Nitrospirota (n = 7). These draft genomes provid
