Plastid endosymbiosis without gene transfer - dinoflagellates can do it #ProtistsOnSky #Kareniaceae #plastids
Recent plastid replacement in Karlodinium ballantinum (Kareniaceae, Dinoflagellata) challenges the paradigms of endosymbiotic gene transfer
Abstract. Plastids, the photosynthetic organelles of eukaryotes, arose via endosymbiosis of cyanobacteria by a eukaryotic host and were subsequently spread

Very excited to dive into the diversity of FRESHWATER perkinsids of the Masurian Lakeland together with Anna Karnkwoska - supported by a joint grant from the Polish and Czech grant agencies NCN & GAČR! #perkinsids #freshwater #protistsonsky
Anna Karnkowska@ankarn.bsky.social · 3w ago🎉 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!
This was the last seminar before summer break - come back in September for more dinoflagellate goodness! The date and time will be shared via email list, discord and on the website (where you can sign up to be on the email list/discord): sites.google.com/view/dinosph... #protistsonsky

Nice to meet you, Holdonia! #protistsonsky
Liz Cooney@protistwtmostest.bsky.social · 2mo agoMeet Holdonia, a new member of the chrompodellid clade. Found clinging to a polychaete, this little guy reveals that similar patterns in plastid reduction have occurred independently across chrompodellid and related lineages. @rhizalyssa.bsky.social @pjkeelinglab.bsky.social tinyurl.com/2t25xb6z

Important announcement!!! 💫 Would you have a tooth pulled if it helped your chances to get an important grant funded? Absurd question, but the funding situation is so bad, that I bet some of you actually considered it for a second… keep your teeth! we created something that might help! 👇 (1/16)

I know late to the party and all but very excited to see this: support for the hypothesis that increased prey specificity correlates with more tightly integrated kleptoplasts – from @mixotrophe.bsky.social lab (wrong image associated with link) #protistsonsky onlinelibrary.wiley.com/doi/full/10....
Increased prey choice is associated with higher kleptoplastidic reliance in Mesodinium ciliates
Kleptoplastidic organisms display varying levels of reliance on stolen plastids, with some lineages evolving complex strategies for plastid (and other organelle) integration into metabolism. More com...
