Algal pyrenoids—condensates that mediate ~1/3 of Earth’s CO2 fixation—change size and number as cells divide. Our data suggest a simple control mechanism: a kinase that continuously ejects material from the condensate! ☀️🌍🔬💧 #Biophysics #Photosynthesis biorxiv.org/content/10.110…
New in Nature Communications: Our study uncovers how green algae coordinate the CO₂-concentrating mechanism and photorespiration during low CO₂ acclimation. This has implications for oceanic carbon cycling. 1/4 nature.com/articles/s4146… #Algae #Photosynthesis #ClimateScience
I am pleased to announce the opportunities in my lab for PhD candidates interested in exploring CO2 sensing in microalgae, the regulation of photosynthesis, the roles of novel chloroplast punctate structures, and chloroplast function. If you or someone you know is curious about…
New Article: "A promiscuous mechanism to phase separate eukaryotic carbon fixation in the green lineage" rdcu.be/dWVIx A key Rubisco phase-separating protein in the CO2-fixing pyrenoid of Chlorella algae. May aid in engineering CO2-supercharging pyrenoids in plants
Check out this Research Briefing for a quick overview of our work exploring Rubisco condensation by CsLinker, an intrinsically disordered protein from Chlorella. All driven by @james_r_barrett doi.org/10.1038/s41477…
The final version of our PyShell🥧🐚 paper is now online @CellCellPress. Check out how diatoms soak up 20% of the Earth's #CO2!🌏 📜 sciencedirect.com/science/articl… Brilliant work by @DemulderManon, @Jorgendottir, Ginga, Aki, Giovanni, Genji, Yusuke, and all the rest of our collabs 🤗
Meet the PyShell!🥧🐚 Diatom pyrenoids fix up to 20% of the Earth's #CO2🌏. We discovered that their Rubisco is encased in a tight protein lattice that is essential for efficient carbon fixation and cell growth🌱 Super excited to share our new preprint📜: biorxiv.org/content/10.110…
Our preprint on the interplay between algal CO2 concentrating mechanism and photorespiration is now available. We have identified LCI20 as a new player in algal photorespiration that delivers amino groups for mitochondrial glycolate metabolism. biorxiv.org/content/10.110… 1/3
