Differences in the relative abundances of Actinobacteria (enriched in dry soils) and Proteobacteria (enriched in wetted soils) matched those of their predicted phages, indicating viral predation of dominant bacterial taxa.
Our most recent paper is out @NatureEcoEvo! We characterized the temporal dynamics of viral, bacterial, and relic DNA via a highly replicated microcosm setup: 4 grassland soils, 7 time points, 144 viromes, 84 metagenomes, and 84 16S rRNA gene profiles. rdcu.be/dnk6S
Despite vast compositional differences across soils, rewetting of dry soils consistently resulted in a bloom of viral diversity (up to a >30-fold increase in vOTU richness 24 h after wet-up!), followed by extreme turnover of viral populations.
I am looking for papers where marker gene data (16SS/ITS) and shotgun metagenome data are analyzed together??
Our lab at UC Davis is looking for a soil viral ecology postdoc, but we can't formally advertise it yet, due to [recent successful negotiations that will absolutely be accounted for]. Avail. now, open to waiting for right candidate. More hopefully soon!
