Disentangling Production and Persistence of Extracellular Virions in Grassland Soils with SIP-Viromics
By applying a genome-resolved stable isotope probing viromics approach to rewetted grassland soils, this study reveals that while only a small fraction of extracellular virions are actively produced during the first week, the majority persist as a stable "viral seed bank" targeting rapidly resuscitating bacterial hosts, thereby serving as a crucial genetic reservoir for microbial turnover and biogeochemical cycling following environmental disturbance.
