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.

The Simons Foundation has amazing #postdoc #fellowships for anyone interested in #marine microbial #ecology or #evolution.

I'd love to sponsor anyone interested in viral diversity!

Please spread the word!

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!

Hoping to see some new #science folks exploring Mastodon so figured it’s time for another #introduction - I’m Mya, a professor at the University of South Florida College of Marine Science. Our lab studies #microbes (bacteria, viruses, protists) in the oceans and other environments and also works on #fish egg identification. I also post about my cute dog and cat a lot! #USFCMS #ocean #marine #oceanography #microbiology #virology #research #seagrass #urchin #academia


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.

Lots of hard work from former PhD student in my lab Carolina Martinez. Part of a collaboration with @pseudacris

We are enjoying the new process so far and working on revisions to address some of the concerns raised by reviewers.

#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."
