Multi-physics modeling for ion homeostasis in multi-compartment plant cells using an energy function Author summary Osmosis is a physical effect by which water is attracted into compartments with a high concentration of solute. Plant cells exploit osmosis to attract water into their subcellular compa...

Plant cells at the organ surface use mechanical cues to activate a specific growth control programme During morphogenesis of multicellular organs, cells acquire distinct identities that meet specific functional requirements. Epidermal identity is widely considered essential for plant morphogenesis du...

Thrilled to share our latest work: how plants control growth through activation of a surface-specific growth programme. Thanks @zoenv.bsky.social, @nathan-german.bsky.social and the other coauthors for all the hard work! 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 🌱🔬
