This story is now published in @natplants.nature.com ! 🎉🎩 Check out the final article here: nature.com/articles/s41477-026-02361-1 Very similar to the original bioRxiv preprint, with the addition of some cool polysome analysis (in the supplementals)! Thanks and congrats to everyone involved! 🙏
Chloroplast-encoded small subunit extensions reshape the Chlamydomonas chlororibosome - Nature Plants
Using in situ cryo-electron tomography, researchers found a unique ‘arm’ domain on the small subunit of Chlamydomonas chlororibosomes. This discovery suggests that chlororibosome structure is more evo...

Florent Waltz@florentwaltz.bsky.social · 6mo agoLong in the making, but happy to present the Chlamydomonas chlororibosome! Cryo-ET🔬reveals a large new domain on the small subunit, built from multiple extensions in conserved ribosomal proteins. bioRxiv 📖: shorturl.at/q44tG This suggests greater chlororibosome diversity than expected! 1/n 🧵
New preprint! 🧵 Best #Cercozoa genome alert! For a decade, I’ve studied protist ecology through questions like who eats whom. But beyond “they eat this, they eat that,” what do #protists do to their environment, biochemically speaking? #protistsonsky @huesnaoeztoprak.bsky.social
So happy to share our new paper out now in @natmicrobiol.nature.com! We establish Pirsonia-Coscinodiscus as a model pathosystem and uncover how this tiny parasite infects and kills bloom-forming marine diatoms 🌊🦠 rdcu.be/fuQyF

Diurnal Regulation of Flagellar Length and Swimming Speed in the Red‐Tide Raphidophyte Chattonella marina
The raphidophyte Chattonella marina is a harmful algal bloom (HAB) species known for its distinct diurnal vertical migration (DVM), a behavior important for its survival and bloom formation. However,...
