Spatial proteomics reveals carboxysome adaptation and mitochondrial proteome in Paulinella chromatophora
Using LOPIT-DC-based spatial proteomics, Cadena et al. map the sub-organellar protein landscape of Paulinella chromatophora, a cercozoan with evolutionary-early-stage photosynthetic organelles. They f...

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 🎉

Driving to Elk Island park with my family on Canada Day (sons) for kayaking and discussing aquatic microbes. Some things got misheard and so anyway, I am now duty-bound to call for formalization of the concept of Dinoflattulates (particularly gas-producing members of the myzozoa). #protistsonsky

How did eukaryotic cells get their Golgi, endosomes, lysosomes and other endomembrane compartments? We show that endomembrane evolution depends on long periods of neutral molecular exploration, punctuated by sudden leaps. New preprint: www.biorxiv.org/content/10.6...
Evolutionary landscape of endomembrane systems. On top are two possible endomembrane systems, represented as directed graphs (pER: proto-endoplasmic reticulum; PM: plasma membrane; IC: intracellular compartment). In the layer below, endomembrane graphs are represented as nodes (white dots) connected by evolutionarily viable transitions (red lines). Collectively these dots and lines define an evolutionary landscape. The landscape breaks up into less functional (left) and more functional (right) endomembrane systems, introducing a selective bias.

#Ichthyosporea are not just the 5–6 species we and others have helped establish as models. Our recent synthesis suggests that ~95% of their species-level diversity remains uncultivated. In other words, we still know only a fraction of the map! #protistsonSky @ibe-barcelona.bsky.social @prbb.org
