Single-cell-resolved natural giant virus infections reveal conserved protist immunity

Single-cell eukaryotes (protists) are key players in microbial ecosystems. Yet, our understanding of how they interact with viruses in nature and how antiviral defenses shape these relationships remai...

🌊Paper announcement! 📣 Viral infections rewire the metabolic makeup of their host and thereby create distinct chemical signatures. Can we use metabolic biomarkers to diagnose infections of algal blooms in the ocean? Well, take a look at our new article led by Conny Kuhlisch in @pnas.org >>

Mapping of the viral shunt across widespread coccolithophore blooms using metabolic biomarkers | PNAS

The viral shunt is a fundamental ecosystem process which diverts the flux of organic carbon fixed through photosynthesis during algal bloom events ...
