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 ...

It's been great to virtually host Alex Eve @amjeve.uk, from the Company of Biologists @biologists.bsky.social today at the RDP @rdplab.bsky.social for a wonderful webinar on scientific publishing and the different forms we scientists have to contribute to a fairer system 📣

New pre-print from the lab! We show that the subtilase SBT12a is essential for symbiosome stabilization in Medicago. Using HUNTER proteomics, we even got some of its substrates. Have a look. www.biorxiv.org/content/10.6...

Multifaceted roles of MTL/NLD/PLA1 in plant reproduction: In addition of inducing haploid embryos, loss of OsMTL function in rice 🌾 could lead to triploid embryo formation !! @newphyt.bsky.social ▶️ doi.org/10.1111/nph....

Great discussions today with @daanweits.bsky.social who visited our @rdplab.bsky.social in Lyon, France. Plenty of fresh ideas on plant oxygen sensing, the room definitely had good O₂ levels! 🌱🫧

Happy to share our latest work in collaboration with the lab of @pengbo10.bsky.social. Here, we describe that a formin protein mediates the polarity switch from root hair to infection thread growth during symbiotic interactions. www.science.org/doi/10.1126/...
