Our work on pattern formation in fossil and extant liverworts is out! @dev-journal.bsky.social Check it out if you are interested in fossils, evo-devo, and how mathematical modeling can help us understand the evolution of developmental processes! 🌿🧪 Thread ⬇️

Lateral inhibition governs ancestral cellular patterning in fossil and extant liverworts

Highlighted Article: Comparative and mathematical analyses reveal that oil body cell patterning in fossil and extant liverworts is consistent with a local activation-lateral inhibition mechanism, poin...

📢 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 🧵👇

Recruitment flyer for two postdoc-funded positions in Marie-Cécile Caillaud's group (RDP laboratory, ENS de Lyon, France). Across the top run six scientific images: a line drawing of an Arabidopsis seedling with roots; a 3D digital reconstruction of a shoot apical meristem with orange and purple sectors marking cell lineages; a confocal microscopy image of plant tissue with green cell outlines and red/orange fluorescent nuclei; two paired 3D cell models in orange/green and yellow/purple showing division plane geometry; and a fluorescence microscopy image of a dividing cell with yellow microtubule-like structures and cyan nuclei on a dark background. Below, the title reads "Two Postdoc-funded positions" with an ERC logo, followed by "Deadline: 1st of Oct 2026" and "Starting date: Nov 2026 and onwards" in a bordered box. The body text is organised into sections: PROJECT (describing research into how plant cells orient their division, combining cell biology, molecular genetics, and multiscale mechanical modelling, with a link to the team website), CANDIDATE (looking for motivated candidates with a strong publication record, prior expertise in plant cell biology or biophysics as a plus, working language English), ENVIRONMENT (describing the ERC Consolidator project, the RDP laboratory hosted at ENS de Lyon, an international and gender-balanced working environment, and the city of Lyon), and RECENT PUBLICATIONS (three pinned references: Goldy et al. 2026 in Science Advances, Gascon et al. 2025 in Current Biology, and Lebecq et al. 2023 in Science Advances). An envelope icon box at the bottom right gives instructions to send a single PDF (cover letter, short summary of previous research, CV with publications, and contact details for two to three referees) to marie-cecile.caillaud@ens-lyon.fr.

Our work on the mechanoresponsiveness of actin is out! While plant microtubules have been extensively studied for their role in mechanobiology, actin has very much been ignored. Here we show that actin responds to cellular deformations within minutes and observed it in Marchantia and Arabidopsis!

Science isn’t just a cost. It’s an engine of economic growth. The UK treats scientific R&D as distinct industry in national accounts. It’s ~0.7% of economy, yet ONS identified it as biggest contributors to GDP growth in May after it expanded by 5.1% vs 0.1% overall stocks.apple.com/Aa-EfoztMSEi...

Ever stretch a plastic bag until it wrinkled? Keeping a thin sheet flat while it rapidly expands is surprisingly difficult. So how do growing plant leaves remain flat as they rapidly grow? Check out our new @currentbiology.bsky.social review, How to Grow a Flat Leaf www.cell.com/current-biol...

How to grow a flat leaf

My postdoc preprint is now online @biorxiv-plants.bsky.social. We established HYDRA, a shoot regeneration assay in Arabidopsis without exogenous hormones, and show that photosynthesis-derived carbon drives regeneration via RBR1 pathway–mediated cell cycle activation. www.biorxiv.org/content/10.6...

Photosynthesis-derived carbon gates cell cycle activation to enable hormone-autonomous shoot regeneration

Shoot regeneration is a powerful model for cell fate reprogramming but how it occurs in nature remains poorly understood because studies in Arabidopsis thaliana conventionally rely on in vitro assays ...

Since the 1960s, the genetic code has been used to predict protein sequences from DNA and mRNA sequences. Our @nature.com article demonstrates that these predictions miss thousands of protein sequences present in human tissues. www.nature.com/articles/s41... 1/

We report many proteins not predicted by the genetic code. They are stable & abundant O( 10³ ) copies / cell. Generative mechanisms include codon-anticodon mismatches & RNA modifications. Their abundance depends on codon frequency & protein stability. www.biorxiv.org/content/10.1...
