📣 A new preprint by noashima.bsky.social! 📣 How does ocean warming affect viral infection? Infection of algae by a giant virus is arrested intracellularly under elevated temperature, with the late replication stage blocked. Infection can later resume, revealing a reversible arrest state 🌊

Reversible inhibition of viral life cycle in response to elevated temperature in a bloom-forming alga
Ocean warming is expected to reshape microbial interactions and community composition, with profound consequences for marine biogeochemical cycles. Host virus dynamics are central to these processes, ...

Our paper is out! Giant viruses lay silent in algal genome across generations, but reactivate in reproductive cell types and under specific environnemental condition to produce virions. Thank you all for your contributions !

Latent endogenous viral elements drive active infection and inheritance in a multicellular host
Endogenous viral elements (EVEs) inserted in host genomes are often regarded as inert relics of past infections. Whether they can retain infective potential and contribute to active viral cycles has r...

Diatom phytochromes integrate the underwater light spectrum to sense depth - Nature
This study demonstrates that diatoms with phytochrome photoreceptors can detect and functionally respond to the entire visible light spectrum through these sensors, enabling them to sense depth a...
