Apoplastic barriers are essential for nodule formation and nitrogen fixation in Lotus japonicus
Establishment of the apoplastic root barrier known as the Casparian strip occurs early in root development. In legumes, this area overlaps with nitrogen-fixing nodule formation, which raises the possi...

Presentation by Noe Arroyo an @lipme-toulouse.bsky.social alumni (PhD supervised by @lnl24.bsky.social) at #RPB2025 “prophase diversity in Xylella fastidious” work he carries out @ IRHS.
Really proud of @ibrahimkeita.bsky.social presenting his PhD work on symbiotic long non-coding RNAs 🧬🌱 at #RPB25 👏 👏 Ibrahim is funded by @inrae-dpt-spe.bsky.social and @occitanie.bsky.social #plantscience

Big day today! @leapedinotti.bsky.social defending her PhD thesis!!! Léa has worked with @nicolasfreiditfrey.bsky.social on the role of CLE/CEP peptides during AMS. See her first chapter recently published 🔽 www.cell.com/current-biol...
Check our updated preprint lead by @malick-mbengue.bsky.social and Eve Teyssier⬇️ A discovery and a big question! - LysM-RLK have played a symbiotic function for 450+ million years (yes, as old as the land plants ☘️ !) - What if CO and LCOs were not essential for AM symbiosis after all ?
Malick Mbengue@malick-mbengue.bsky.social · 2y agoDelighted to present an updated version of our LysM-RLK/AM symbiosis story in Marchantia! @lrsv-toulouse.bsky.social www.biorxiv.org/content/10.1...
