Together with @plantophagy.bsky.social, we have an opened postdoc position for a young scientist that graduated after 01/01/2025, see ad attached

Our latest for your summer reading list: how do plants control growth at the organ surface? So proud of @zoenv.bsky.social's magnum opus and grateful to all the other authors, including Annamaria Kiss, @nathan-german.bsky.social, and @moritznowack.bsky.social! www.cell.com/current-biol...

Plant cells at the organ surface use mechanical cues to activate a specific growth-control program

Nemec-Venza et al. show how mechanical signals, such as tissue tension, can activate gene expression in epidermal cells at the surface of Arabidopsis roots. The expression of the edge-specific growth ...

@babliadhikary.bsky.social, Higashi et al. show that PAK4 drives dynamic vertex remodeling in cells and embryos through spatiotemporal regulation of #myosin II. Inhibition of PAK4 disrupts tissue packing and compromises junctional continuity and barrier function. rupress.org/jcb/article/...

📢 Two postdoc positions available in @mc-caillaud.bsky.social's group (RDP lab, ENS de Lyon), part of an ERC Consolidator. Project: how plant cells orient their division, combining cell biology, molecular genetics, and mechanical modelling. 📅 Deadline: 1 Oct 26 | Start: Nov 26 onwards Details 🧵👇

In an heoric endeavor, Xiomin Liu, PhD student in the lab, characterized the dynamics and topology of the cell division machinery during cambium stem cell divisions. Super fruitful collaboration with the group of Sabine Müller (@phragmoplast.bsky.social). doi.org/10.1111/nph....

Congratulations to Gwennogan Dubois, Marija Smokvarska, and Jessica Perez Sancho, who were honored at the French Academy of Sciences during the “Grandes Avancées Françaises en Biologie” event! 👏 A source of great pride for the lab, alongside their research directors Emmanuelle Bayer & Yvon Jaillais.

[1/n] Our preprint-in-progress on RNA regionalization in Stentor is no longer in progress! Now @pnas.org 🥳 Turns out a single cell isn't a homogenous soup… it has molecular geography, including things like regionalized transcription factors. Think bicoid, but in a ciliate.

Starting to write up the first mechanistic paper from my lab about regulation of endosomal PI(3)P. We see retromer tubules (Vps35) budding from PI(3)P positive sorting endosomes with Actin at the neck. When PI(3)P homeostasis is perturbed this organisation breaks down and cells cant recycle cargo.

Science Magazine@science.org · 2mo ago

New research in Science reveals that the Venus flytrap's snap is triggered by a rapid softening of the epidermal cell walls, uncovering the physical mechanism behind this remarkable movement. Learn more in this week's issue: https://scim.ag/4fXQ9sn
