摘要

Hot springs are natural laboratories for studying microbial diversity, evolution, and adaptation to extreme environments. Despite their abundance across the Western US, information about the functional and genomic structure of inhabiting microbial communities is restricted to a handful of locations. Here we present a dataset of 500 deep metagenomes, totaling 3.38 terabasepairs and collected from 56 remote hot springs across the US Great Basin and Yellowstone, with 25 of the hot springs surveyed annually over 4 consecutive years. Additionally, we present 780 bacterial and archaeal metagenome-assembled genomes (MAGs) binned from these metagenomes, with completeness ≥80% and contamination ≤5%, of which 149 are considered “high quality”. Many of the MAGs likely represent entirely novel genera and even families, relative to the Genome Taxonomy Database. Our spatiotemporally extensive dataset yields insight into the microbial functional structure at dozens of previously unstudied locations, substantially expands our repertoire of extremophile microbial genomes, provides a new resource for high-temperature biotechnology, and enables future phylogenomic studies of these communities through space and time.
