4/4 Our data supports the convergent evolution of a biomolecular condensate. We show that the main pyrenoid assembly protein, SUPA1, has minimal sequence conservation to characterized unicellular algal Rubisco-condensing proteins, binding to a different surface region of Rubisco.

3/4 We provide a unique insight into Rubisco condensation. We combine multi-discipline approaches to reveal the helical folding of Rubisco Binding Motifs upon binding, combined with steric hindrance that halves the available binding sites from eight to four.

2/4 Previous understanding in seaweeds is limited to physiological studies, here we map out a comprehensive spatial atlas of the carbon fixation machinery revealing multiple unique features, for example 68 pyrenoid associated proteins localizing to different sub-domains.

1/4 Until now, seaweeds have proven to be recalcitrant to robust large-scale genetic manipulation. We have developed large-scale fluorescent protein tagging, localizing 160 proteins to provide an unprecedented insight into the spatial organization of seaweed CO2 fixation.

Excited to share our latest preprint on #PhycologyFriday. We map out the carbon fixation pathway for the first time in a multicellular alga, the green seaweed Ulva, and reveal a unique Rubisco-Linker interaction in the pyrenoid, a chloroplast condensate. Below I summarize some key points. #seaweeds

Ending the summer with two great meetings: #ccm11 in York and #seawheat in Bremerhaven. Excellent science, nice places to visit. A nice time with colleagues. Now time to get back to the lab 👨‍🔬

Júlia from the PGE group presents her work during the New Technologies session at #NGSB24

Ready to kick off #NGSB24 here in Ghent! @viblifesciences.bsky.social

Happy to share our new preprint on this new platform: www.biorxiv.org/content/10.1... We designed new selection systems for the green seaweed Ulva and benchmarked different CRISPR/Cas applications to install targeted mutations.
