I'm excited to share that my newly funded #ERCStG FRONTERA is recruiting two postdoctoral researchers at @ipbhalle.bsky.social 🌱🔬 If you are passionate about plant immunity, proteolysis, membrane proteins, or proteomics, I'd love to hear from you. 🧵 Please RT/share!

Our work, Progressive oxygenation of developing leaves directs morphogenesis, is now out in Science Advances! We found that developing leaves oxygenate from tip to base, strikingly mirroring their developmental axis, and this drives leaf dev. www.science.org/doi/10.1126/sciadv.aef2430 #plantscience

Our new preprint shows that metacaspase-mediated proteoform generation and N-degron pathway-dependent proteoform stability act together to diversify UBP6 function during Arabidopsis immunity www.biorxiv.org/content/10.6...
