Finally this work from the @rdplab.bsky.social is out and I am so proud of it! doi.org/10.7554/eLif... We find that the petal homeotic regulator PhDEF mostly acts in the epidermis in petunia petals: most of its binding and regulatory targets are there, with a limited action in the mesophyll (1/9)

Super cool seminar today @rdplab.bsky.social from @haesleinhuepf.bsky.social, a must-hear perspective on AI in image analysis!

@mc-caillaud.bsky.social's talk at #SLS26 suggests actin-mediated regulation allows flexible implementation of a shared core strategy, favouring division perpendicular to the growth axis and symmetric partitioning, while avoiding lateral wall anchoring. www.ens-lyon.fr/RDP/signalis...

🎓 Congratulations to Laëtitia DE FARIA on her brilliant PhD defense! 🌱 Great work on epigenetics and male fertility, under Daniel Bouyer’s supervision. 👏 Thanks to the jury: Pauline Jullien, @pierrebaduel.bsky.social, @arabette.bsky.social, @leandroquadrana.bsky.social & @thomaswidiez.bsky.social

The crowd ! #INTERFACE2026 First edition of the french "plant membrane interface" meeting here at @ensdelyon.bsky.social hosted by @rdplab.bsky.social sponsored by @cnrsbiologie.bsky.social

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...

Join the team for this very cool project! Don’t hesitate to reach out if you have any questions. And since it’s a very interdisciplinary project, reposts to reach the right person (not necessarily with a plant background) are appreciated 😁

Happy to share our protocol for imaging double fertilization in maize! 🌽🔬 📖 www.biorxiv.org/content/10.6... We hope this resource will be useful for researchers studying plant reproduction, fertilization, and early seed development.

What is an edge? Why is this geometrical domain so crucial during plant morphogenesis? Read our review, co-written with Antoine Chevalier and @ckirchhelle.bsky.social to find out! authors.elsevier.com/c/1nAnf4tPF4...

Incredibly proud of this paper showing how plants couple vesicle delivery and phragmoplast expansion during division. This project started in the lab of the great and late Ian Moore, and it was a joy to finish it with @liamelliottplants.bsky.social et al! link.springer.com/article/10.1...

How do different clonal layers interact to make a leaf flat? How do they integrate genetic and mechanical cues to achieve this remarkable feat? That is precisely what we answered through our work! Special thanks to all contributors! www.biorxiv.org/content/10.6...

🌽 Save the date! Join us in Lyon, France for the 7th European Maize Meeting 📅 June 9–11, 2027 More details coming soon — stay tuned! Please share with colleagues and networks interested.

Ever wondered what makes some alleles dominant (A) and others recessive (a) ? In our new paper, we explored how a series of recently discovered "dominance modifiers", genetic elements that have long remained elusive, achieve their regulatory function. journals.plos.org/plosgenetics...
