Exploring the great microbial eukaryote diversity and evolution, one protist at a time. I’m fascinated by this question: how have #plastids evolved? #ProtistsOnSky | Associate Prof at Uppsala University. My lab: https://www.burki-lab.net/

A new preprint from us using a single-cell genome pipeline to investigate diversity of uncultured Bodo spp. flagellates.

We isolated 7 Bodo spp. cells from a single environmental sample and show that they represent 3 Bodo sp. each with a unique species of bacterial endosymbiont. #protistsonsky
Single-cell sequencing reveals unexpected genetic diversity among Bodo spp. flagellates and their bacterial endosymbionts
Bodo is a cosmopolitan genus of free living bacterivorous single-celled flagellates in the class Kinetoplastea. Members of genus Bodo are considered the closest free-living relatives to the parasitic ...

This is two stories in one: a case study/cautionary tale on developing genetic tools in new organisms, and the first hint at a gene regulatory network for choanoflagellate multicellular development (which turn out to involve a Hippo/YAP/ECM loop!) A 🧵

I've seen this several times: when Acantharians get big enough they like to eat tintinnids. And they always orient with the lorica opening pointed in: like they are slurping up a little jello shot. That glass house can't protect you from these weird predators little ciliate! 🦑 #protistsonsky

Study reveals the hidden genomic diversity & global distribution of Phaeocystales — bloom-forming algae with surprising mixotrophic strategies, viral integrations, & adaption to polar vs temperate zones. #protistsonsky
Big step forward for marine ecology & biogeochemical models. 🧬🌊

Very true. The time it takes to gain energy back after teaching a class is often not properly factored in

I have thousands of #marineplankton microscopy images and measurements and would like to make these available to researchers. Where’s the best place to put them and how do scientists like their metadata? 🧪🦑

While it could have been a wild goose chase, finding this one is special to me because we were stacked against the odds

Excited to share our third heterotrophic #Paulinella culture from Haida Gwaii, Canada! :)

These are good changes, especially this: B1 <<should allow the panels to answer the question “is this a great idea that would be worth pursuing?”, while the question for>> B2 <<is “can that idea be pursued realistically, and if so, in the manner and with the approach that the applicant proposes?”>>

Based on feedback from applicants, reviewers and broader research community, the ERC Scientific Council decided to make changes in the 2026–27 calls for proposal for research funding.

We have tried chemical fixation but this was not successful with these "bottle" cells, and we don't have easy access to cryo. @fmikus.bsky.social did plunge one of our cultures when we were at UBC, but I haven't heard how this went

Expanding our Paulinella factory and hopefully more to come. @thealgaeman.bsky.social is the master grower, quite a tour de force for these very rare cells. @erc.europa.eu supported research

Our 2nd heterotrophic #Paulinella culture!
Really proud of this one. After days at the microscope picking cells, I finally got it growing happily :)
