Who are giant viruses infecting in the ocean?

In a collaborative paper with the Vardi lab, we were able to link many giant virus lineages to protist hosts using #SingleCell #RNASeq. One #protist host (leucocryptos) made up less than 1% of the community, but we could still identify a cryptic viral lineage infecting it, leading to population collapse.

Single-cell RNA-seq of the rare virosphere reveals the native hosts of giant viruses in the marine environment - Nature Microbiology

Active infections of giant viruses in their marine protists hosts are tracked at single-cell resolution, showing that, despite being rare, these viruses still impact microbial population dynamics.

"Exploring the mechanisms that underpin #symbiosis requires an understanding of how these complex interactions are maintained in diverse model systems. The ciliate #protist, Paramecium bursaria, offers a valuable insight into how emergent endosymbiotic interactions have evolved."
