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/
We 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

I had missed this when it came out at the end of last year, but I am glad to see some of my *favourite* eukaryotic supergroups marked as resolved #protistsonsky

Haida campaign is a wrap, fingers crossed we hit the jackpot

We’ve come a long way to sample on Haida Gwaii (BC). Inspired by this paper, we have traveled to the same place in the hope that we are going to find again these Paulinella species #protistsonsky

This sampling campaign for heterotrophic Paulinella involves digging lots of holes on the beach #protistsonsky @thealgaeman.bsky.social on the photo

Summer post. Yash @thealgaeman.bsky.social found Paulinella in this sample I collected on Venice Beach (LA) almost as an afterthought.🤞it will grow #protistsonsky

Putting geochemists, paleontologists and molecular phylogeneticists together 🤯 can we reconcile everyone?

Happy to have played a small part in this. Prometheid is a proposed supergroup that contains previously deep orphan lineages.

#protistsonsky any ID on these cells? Can someone point to a description? They come together and form aggregate. Cercozoa of some sort?

First attempt at #ExM in my lab was a success, after a training boot camp by king of the method @dudinlab.bsky.social. Lots of details to iron out, but here is a pretty picture of Cryptomonas (testbed species) #protistsonsky (confocal: Anne Walraven)

So today is a huge satisfaction to see this instrument (Fluorescence-Activated Cell Sorting, FACS) finally here. Let us do science now (although we are still missing a compressor).

Stoked about this manuscript, many years in the making. We present an original resource of ~700 highly curated plastid MAGs of marine pelagic algae. Among these we found a novel deep branching group of plastid genomes; we informally call them leptophytes
