This Halloween, we have a spooky evolutionary story for you. The brainchild of @delaconcepcionjc.bsky.social, Nick Irwin and our fantastic collaborators is now out in @natplants.nature.com www.nature.com/articles/s41... Here’s why I love this work — and why I think you’ll enjoy it too. 👇

My main work as postdoc @plantophagy.bsky.social lab in @gmivienna.bsky.social is out in @natplants.nature.com 🌱🎉 We asked how can protein complexes diversify without compromising their function and explored this question using the plant #exocyst complex. www.nature.com/articles/s41...

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 www.biorxiv.org/content/10.1...

7 years ago,I sat outside @zmbp-tuebingen.bsky.social,gathering the courage to begin a new chapter as a group leader. Now in Bochum, I still need that courage to face challenges—both inside & outside the lab—but after all I’m grateful that I still find joy in what I do. #happybirthday #theustunlab

Outstanding work by @anyalb.bsky.social in my lab - she targeted enzymes to synthetic biomolecular condensates in plants and showed increases in metabolic pathway activity, likely due to protection of the introduced enzymes from proteolysis #PlantScience onlinelibrary.wiley.com/doi/10.1111/...

The final version of our study on SERK-BIR module in Marchantia is out. Congratulations Cate and many thanks to collaborators! www.sciencedirect.com/science/arti...

I am happy to introduce this bioRxiv. Stomatal opening is crucial for gas exchange, but it unavoidably offers invasion by pathogens. We found that by coronatine (COR), Pto DC3000 exploits CYP707A1 activation in Arabidopsis thaliana, encoding an enzyme that degrades ABA, for stomatal invasion.

Our manuscript on the DOG1 dormancy pathway is out! 🥳 It started with a phosphoproteome when working @mpipz.bsky.social and 10 years of hard work @uni-muenster.de from Guillaume Nee with Thorben Krüger and more to prove that AFPs are target! #proteomics #seed www.science.org/doi/10.1126/...

Very happy that our story on dormancy control by DOG1-PP2C is now published in Science Advances. We found that DOG1 prevents the activation of AFPs by AHG1. This is the result of a great team effort led by Guillaume Née. Summary of key findings below🧵 www.science.org/doi/10.1126/... @science.org
