“…The GSV Atlas also contains many viral amino acid biosynthesis and degradation pathways that could be critical in viral infection and replication (e.g., KO:00250, KO:00260, KO:00270, KO:00330, KO:00340, Figure S6). Amino acids are building blocks for new cellular material and can support soil biogeochemical cycles, as they serve to enhance the carbon cycle through priming effects and/or enhanced nutrient availability 93–96 (e.g., KO:00500, KO:00052, KO:00051, Figure S7). Collectively, these pathways demonstrate several possibilities for critical impacts of soil viruses on processes that are central to microbial metabolism and biogeochemical cycling of elements in soil.…”

Historically neglected by microbial ecologists, soil viruses are now thought to be critical to global biogeochemical cycles. However, our understanding of their global distribution, activities, and interactions with the soil microbiome remains limited. Here, we present the Global Soil Virus (GSV) Atlas, a comprehensive dataset from 2,953 soils that comprises 616,935 uncultivated virus genomes (UViGs) and 38,508 unique viral operational taxonomic units (vOTUs). Rarefaction curves from the GSV Atlas indicate that most soil viral diversity remains unexplored, further underscored by high spatial turnover and low rates of shared vOTUs across samples. By examining genes associated with biogeochemical functions, we also demonstrate the viral potential to impact soil carbon and nutrient cycling. This study represents the most extensive characterization of soil viral diversity to date and provides a foundation for developing testable hypotheses regarding the role of the virosphere in the soil microbiome and global biogeochemistry.
