Abstract As central members of soil trophic networks, viruses have the potential to drive substantial microbial mortality and nutrient turnover. Pinpointing viral contributions terrestrial ecosystem processes remains a challenge, as temporal dynamics are difficult unravel in spatially physicochemically heterogeneous environment. In Mediterranean grasslands, first rainfall after seasonal drought provides an reset, triggering activity during tractable window for capturing short-term dynamics. Here, we simulated precipitation microcosms from four distinct, dry grassland soils generated 144 viromes 84 metagenomes characterize viral, prokaryotic, relic DNA over 10 days. Vastly different communities each followed remarkably similar successional trajectories. Wet-up triggered significant increase abundance richness, by extensive compositional While turnover prokaryotic was much less pronounced, differences relative abundances Actinobacteria (enriched soils) Proteobacteria wetted matched those their predicted phages, indicating predation dominant bacterial taxa. Rewetting also rapidly depleted DNA, which subsequently re-accumulated, new days wet-up, particularly taxa putatively under phage predation. Production abundant, diverse particles via host cell lysis appears be conserved feature early response rewetting, results suggest ‘Cull-the-Winner’ dynamics, whereby infect cull but do not decimate populations.

Viral metagenomics reveals diverse virus-host interactions throughout the soil depth profile

mBio, Journal Year: 2023, Volume and Issue: 14(6)

Published: Nov. 30, 2023

Soil viruses can moderate the roles that their host microbes play in global carbon cycling. However, given most studies investigate surface layer (i.e., top 20 cm) of soil, extent to which this occurs subsurface soil below is unknown. Here, we leveraged public sequencing data interactions between and hosts at depth intervals, down 115 cm. While were detected throughout profile, adaptation varied. Nonetheless, uncovered evidence for potential encourage recycle plant-derived both soils. This work reasons our understanding viral functions requires us continue dig deeper compare existing ecosystems.
