Thrilled to have been awarded an ERC Starting Grant 2026 to study the coordination of developmental programmed cell death in plants! I am very grateful to everyone who has supported me along the way. Looking forward to this exciting new scientific adventure!

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

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 ...

Congrats to Gweenogan Dubois, @smokvarska-marija.bsky.social and Jessica Perez Sancho, awarded on Tuesday at the Académie des sciences for the Grandes Avancées Françaises en Biologie! Together with @yvonjaillais.bsky.social , we were proud to be with them as their research supervisors. 🎉🔬

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...

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...

Dominance modifiers at the Arabidopsis self-incompatibility locus retain proto-miRNA features and act through non-canonical pathways

Author summary Many plants avoid self-fertilization through a system of self-incompatibility, which allows them to recognize and reject their own pollen. In plants like those in the Arabidopsis family...
