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 transferAbstract. Plastids, the photosynthetic organelles of eukaryotes, arose via endosymbiosis of cyanobacteria by a eukaryotic host and were subsequently spreadacademic.oup.comVery 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🎉 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

Liz CooneyMeet 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
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 ciliatesKleptoplastidic organisms display varying levels of reliance on stolen plastids, with some lineages evolving complex strategies for plastid (and other organelle) integration into metabolism.

Extremely cool PhD position alert! Plus a great supervisor!
Fabien BurkiWe are looking for a PhD student to work on an exciting plastid endosymbiosis in microbial eukaryotes. This position involves sampling, exciting microscopy such as CARDFISH, ExM and FIBSEM, single-cell transcriptomics and more. #protistsonsky 1/2
Please join us next week for the second iteration of the DinoSphere Seminars! This time our two speakers will talk about host-associated dinoflagellates and any challenges they might have encountered when working with them. All current and future friends of dinoflagellates welcome! #ProtistsOnSky
