Our work on mapping the dynamics of phospholipids during lateral root formation is now published in @jxbotany.bsky.social We show that PI(4,5)P₂ plays a key role: targeted reduction in pericycle promotes LR development. → academic.oup.com/jxb/advance-...

🚨 New in Developmental Cell @Dev_Cell Our team uncovered how plants sense phosphorus deficiency and delay flowering — a molecular “switch” that links nutrient stress to development. A step toward breeding nutrient-smart crops! authors.elsevier.com/a/1m2id5Sx5g... @MSU_PRI @MSUAgBio @MSU_PSM

We have two open Post-Doc positions in my group at the interface with: 1- @ataly.bsky.social for molecular dynamics 2- Bruno Guillotin from protein mobility Apply by sending CV, two ref letters and a short motivation letter to me : [email protected]. Deadline 15 sept.

This is a fantastic talk by Chris Hawes @nhm-london.bsky.social. He speaks about #PlantMicroscopy in particular, but also the History of #Microscopy. www.youtube.com/watch?v=eAFZ... Have a look at this Obituary of Chris, too: onlinelibrary.wiley.com/doi/10.1111/... #PlantScience

One of the key aspects influencing morphogenesis is mechanics. We mapped the mechanical properties of living roots at the tissue and cellular levels using Brillouin microscopy and molecular rotors. www.biorxiv.org/content/10.1...

Evolutionarily diverse caveolins share a common structural framework built around amphipathic discs, say Bing Han, Sarah Connolly, Melanie Ohi (@umich.edu), Anne Kenworthy (University of Virginia) and colleagues: rupress.org/jcb/article/... #StructuralBiology #Membrane #lipid

I set out to review the evolution of eukaryotic intracellular traffic, but along the way a new hypothesis came into focus: maybe the earliest membrane carriers were tubules, not coated vesicles! New preprint: ecoevorxiv.org/repository/v... Here’s the idea. 🧵

Very proud to share our latest preprint: postdoc/LRSF fellow Yue Rui studies the mechanisms regulating attachment of the cell wall to the plasma membrane. The Cellulose Synthase Complex and REMORINs determine the extent of attachment and root osmotic stress tolerance. www.biorxiv.org/content/10.1...
