World's first legally binding treaty to protect oceans and marine life takes effect

The High Seas Treaty will govern about two-thirds of the planet's oceans including vast areas beyond any country's borders.

Very nice study from Henshaw et al shows that #marine heterotrophic bacteria can sense and move towards cyanobacteria when the latter are infected with #viruses.

Presumably the signatures of early infection are a sign that nutrients from a lysed cell will be available soon.

This is a nice study that has implications for understanding the role of viruses in the #ocean.

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.

Daily turnover of active giant virus infection during algal blooms revealed by single-cell transcriptomics

"A consistent percent of infected coccolithophores displayed the early phase of viral replication for several consecutive days, indicating a daily turnover and continuous virocell-associated metabolite production, potentially affecting the surrounding microbiome"

Happy to share our latest paper, in which we examined the timing at which different microbial groups colonized the ocean!

The first author (Carolina Martinez) is starting her lab at UC Santa Barbara in 2024 and is looking to recruit postdocs and PhD students, so if this looks interesting to you, please reach out to her!

Happy to share a collaborative preprint with Assaf Vardi's group in which we use single cell transcriptomics to link giant viruses with their native hosts during a marine algal bloom!

This approach is quite sensitive - we were able to identify viruses infecting one protist group that made up <0.5% of the community.

Homing in on the rare virosphere reveals the native host of giant viruses

Giant viruses (phylum Nucleocytoviricota) are globally distributed in aquatic ecosystems They play major roles as evolutionary drivers of eukaryotic plankton and regulators of global biogeochemical cycles.

#Virus control

This exciting new research explores the influence of #virus #infection in changing the balance of organic matter degradation between #bacteria and #eukaryotes in #marine #carboncycling during #phytoplankton blooms.

Based on #mesocosm studies, this research demonstrates how #viruses infecting different #microorganisms change community dynamics and the release and potential fate of marine carbon from primary production.

Wonderful essay by @vincentflora and Assaf Vardi on viruses in the ocean

Viral infection in the ocean—A journey across scales

"Aquatic virology tackles some of the most challenging questions in microbial ecology and oceanography, trying to understand how microorganisms that are invisible to the naked eye can influence large-scale processes, such as biogeochemical cycles, or affect entire marine food webs."

Bacterial lifestyle switch in response to algal metabolites

Opportunistic bacteria modulate their lifestyle from coexistence to pathogenicity by perceiving the physiological state of their algal host through sensing of algal secreted metabolites.
