I'm a huge fan of #AquaticFungi, but do you know what else are amazing, important, and understudied? #Protists. I'm having a protist-filled Friday, starting with the fantastic ongoing defense of soon to be 'Dr.' @annewalraven.bsky.social of the @fburki.bsky.social lab. Check out her fantastic work 🎉

Apparently the "boring billion" was actually exciting! We provide molecular evidence of complex Mesoproterozoic eukaryotic communities. So happy to see this out 🥳 Thanks to @phoebefossil.bsky.social , Hélène Morlon & @fburki.bsky.social for a lovely collab! doi.org/10.1073/pnas...

1/11 🤩Sooooo happy to see this work on a new new group #algae. Looks like #centrohelids - predatory ancient eukaryotic lineage sometimes harbor vertically-inherited plastids from #dictyochophytes. Amazing work, @annewalraven.bsky.social, glad to be on board! More below:

Very excited that the preprint of the main paper of my PhD is now out! We show that Meringosphaera is the first centrohelid with permanent plastids: doi.org/10.64898/202... @zlatogursky.bsky.social, @pjkeelinglab.bsky.social, prof. Rachel A. Foster, and @fburki.bsky.social #protistsonsky

Single cell genomics and fluorescence microscopy suggest a permanent plastid in a marine centrohelid
Photosynthetic organelles (plastids), which originated via primary endosymbiosis between an Archaeplastida ancestor and cyanobacteria, have shaped the Earth's oxygen-rich atmosphere and spread across ...

Thought I would share an SEM image of a Meringosphaera I picked at Klubban (West Coast of Sweden) for my first post on Bluesky :) #protistsonsky
