The mechanical properties of Arabidopsis thaliana roots adapt dynamically during development and to stress Brillouin microscopy reveals in vivo dynamics of mechanical properties during plant development and response to stress.

Our work now on its final version. We mapped the mechanical properties of roots at tissue and single cell levels using Brillouin microscopy and molecular rotors. Additional mutants and stress measurements from what we previously showed in the preprint are included.

Plant Kelch phosphatases are Ser/Thr phosphatases involved in cell cycle regulation Brassinosteroids (BRs) are plant steroid hormones sensed at the cell surface by the membrane receptor kinase BRI1. Activation of BRI1 leads to the dephosphorylation of BZR1/BES1 transcription factors ...

Our new year starts of course with new preprint on brassinosteroid signaling tinyurl.com/nhzcfkxd. We re-analyzed the function of Kelch phosphatases, which were previously characterized as protein tyrosine phosphatases that dephosphorylate the critical pTyr200 in the GSK3 kinase BIN2. (1/6)

🎄 What an eventful year this has been! And what a privilege to work with such a wonderful team! 🎅

Cell wall patterning regulates plant stem cell dynamics The plant cell wall regulates development through spatiotemporal modulation of its chemical and mechanical properties. Pectin methylesterification is recognized as a rheological switch controlling wal...

Thrilled to have our paper out in @science.org. Cell division guides plant cell wall formation. Does the reverse hold? We show that bimodal pectin methylesterification, via PME5 mRNA nuclear sequestration, influences plant cell division and cell plate orientation. www.science.org/doi/10.1126/...

New OA Article: "Cambium LBDs promote radial growth by regulating PLL-mediated pectin metabolism" rdcu.be/eP4mp

LBD TFs in the cambium drive radial plant growth by regulating PECTATE LYASE-LIKE (PLL) enzymes that remodel cell wall pectin, promoting cell expansion.

The University of Toulouse has 44 postdoc positions to fill (Horizon Europe MSCA-COFUND). My lab is looking for candidates to apply and work on how plants regulate cell surface levels of receptors or transporters in response to heat. Please DM me if interested!

I am beyond thrilled (like the screaming and jumping type of thrilled) that my SNSF Starting Grant was funded. I will start my own lab @unibe.ch next year, studying succulent anatomy development and if and how this anatomy is required for efficient CAM photosynthesis in different Kalanchoë species 🌱

My new Emmy Noether Group is recruiting!

🔬 Two PhD positions in plant pathogen evolution

🧬 Start: April 2026 (flexible)

📍 Dept. of Phytopathology & Plant Protection @rstam.bsky.social @uni-kiel.de

⏰ Apply by 15 Dec 2025

🔗 More info: www.uni-kiel.de/personal/de/...

Do get in touch or share 😊

This Halloween, we have a spooky evolutionary story for you.
The brainchild of @delaconcepcionjc.bsky.social, Nick Irwin and our fantastic collaborators is now out in @natplants.nature.com www.nature.com/articles/s41...
Here’s why I love this work — and why I think you’ll enjoy it too. 👇

New pre-print from the team!

The manuscript is @emma-raven.bsky.social's PhD work showing that whether a leaf is a carbon sink or a carbon source influences how they execute immune responses.

Have a read!

@johninnescentre.bsky.social

I was tremendously lucky to be in @xanderjones.bsky.social's lab to watch @bijuntang.bsky.social move from technician to PhD to Postdoc and produce this magnum opus. #SalicS1 is the just reward for years of brilliance and hard work.Well done Bijun, Xander, Jing, and everyone involved! #SalicylicAcid

Very excited to see our @nikogeldner.bsky.social lab x Feng Zhou lab work featured on the cover of Science!
(1/5) We reveal how root architecture and nutrient leakage shape spatial patterns of microbial colonization, moving beyond traditional models of uniform exudation.

Congratulations Merissa! Such an exciting story!!

Happy to share slightly late that the main work of my PhD is now published! How do plants regulate the number + location of growing branches 🌳🌲? We used experiments and mathematical modelling to study how local and systemic signals are integrated during shoot branching regulation. A thread:

News on PILS & ERAD! Big congrats to @seinabnoura.bsky.social @kleinevehnlab.bsky.social and colleagues!

Congratulations! Exciting news! Many years ago I was a student there! Lots of fond memories. I’m looking forward to what’s coming from your group in the years to come!

Call for a tenure-track position at our Department of Plant Molecular Biology in Lausanne! We are searching for promising early-career researchers in the broad field of plant-organismal interactions. Deadline: November 30, 2025 - Please re-post!
