🎉 Excited to share that Elisabeth Hehenberger and I have been awarded a 🇵🇱🇨🇿 NCN–GAČR grant! We'll explore the diversity, ecology, and interactions of Perkinsea, a fascinating and largely overlooked group of parasitic #protists in #freshwaters. Looking forward to this exciting collaboration!

Really excited to share our new paper from @ibe-warszawa.bsky.social protist team! 🎉 We dive into protist symbioses and show how these interactions shape ecosystems and have played a key role in the evolution of eukaryotes 🦠

🎉 Big congrats to Alessandro Culicchii, a post-doc in my team! Thanks to the @isme-microbes.bsky.social Mobility Fund, he’s heading to Paris to work with @luciebittner.bsky.social on bacteria and protist association networks in Masurian lakes, using #MicroDivEr data. Good luck! #ProtistOnSky

A large fraction of aquatic bacteria remains uncultured. Here, the authors cultivated 627 strains of abundant freshwater bacteria from 14 European lakes, thus generating a collection that includes many previously uncultured, oligotrophic bacteria that may serve as model organisms.

"Reconstructing the last common ancestor of all eukaryotes" journals.plos.org/plosbiology/... In this Consensus View, we put forth the status quo and an agreed path forward to reconstruct LECA’s gene content. 🧪
 Genetic contributions to LECA.

LECA’s gene repertoire was chimeric, containing genes derived from the Asgardarchaeota-derived host cell, mitochondrial endosymbiont, and potentially other prokaryotic sources, along with a set of eukaryote-specific genes that evolved after the divergence of eukaryotes from prokaryotes.
