Coming to you live from #ISPLORE2025JP Fresh preprint from my lab showing that leaves progressively oxygenate and how this is important for their morphogenesis.Thanks to our collaborators from @Fra_LicO2si lab. #plantscience www.biorxiv.org/content/10.1...

It was already known that auxins (surprise!) had a key role controlling the end of flowering, plant menopause. Now we can tell you how and where they act in the inflorescence meristem to control the process. @irenegonzlez.bsky.social www.cell.com/current-biology/fulltext/S0960-9822%2825%2901002-4

🌱✂️ How do plant cells decide where to divide? Our work shows that actin can override the geometric rules—guiding cells to divide in alternative orientations. #PlantScience #CellBiology #Arabidopsis @camilagoldy.bsky.social @rdplab.bsky.social www.biorxiv.org/content/10.1...

Take a look at part of my work with @mc-caillaud.bsky.social at @rdplab.bsky.social about the role of actin cytoskeleton to maintain cytokinesis against cellular geometry 🌱🔬

New preprint from the lab. We mapped the dynamics of phospholipids during lateral root formation and show that PI(4,5)P₂ plays a key role: targeted reduction in pericycle promotes LR development. www.biorxiv.org/content/10.1...

Really cool study on a fundamental aspect of plant cell mechanics-hydraulics. Congrats to all involved 🌱

Super nice work on how tissue water status can influence cell fate decisions. Congrats to all involved!

Really amazing and inspiring work. When it comes to sensing changes plants have some truly mind blowing tricks up their sleeves. Congrats to all involved!

Dec 6th ...shining brightly There is a lot of talk these days about optimization and efficiency--of governments, of biology. But in a complex and fluctuating world, what is actually desirable? I’m always impressed by Oliver Hamant (RDP, Lyon) grappling with and writing about this.

Stomata form alignments in many species, we do not know how. So, we forced a lot of cells to differentiate into stomata, and we watched them dividing, with modelling, and mechanical perturbations, we conclude that they were aligned by mechanical stress derived from differential growth

🚨 PhD Opportunity Alert! 🚨 I'm thrilled to announce my new project, Watchers on the Wall, exploring how plant cells sense and respond to stress through their walls. 🌱 A 5-year fully funded PhD position is open—please share with potential candidates! 👇 (1/7)
