I’m very happy to share that next year I’m launching the Meristem Hydraulics Group. We will be at the @umeaplantsciencecentre.se (Sweden) & the University of Helsinki (Finland) @helsinki.fi

Here is a brief description of our research interests:

I had a great time writing this dispatch @currentbiology.bsky.social about Jacob Suissa's recent paper on the link between fern phyllotaxis and vascular architecture. "Evo–devo: Ferns flourished due to developmental covariance between leaves and vasculature"

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/...

Out in @science.org this week:
PME5 is sequestered in the nucleus and released during cytokinesis allowing its activity to be timed with cell division.

Excited to share this preprint on the microtubule severing protein Katanin, and its role in cell elongation and division in maize. First author Stephanie Martinez worked collaboratively with many folks to bring you this preprint. Check it out! 🔬🌽 www.biorxiv.org/content/10.1...

(1/10) I am excited to share this signature review from our lab published @jxbotany.bsky.social

Congratulations to @ohazel.bsky.social and @jessicaa-orr.bsky.social (first published paper for Jessica!)

Nuclear positioning and cell division site specification in plants
doi.org/10.1093/jxb/...

Check out this collaborative paper where we identified two new alleles of a myosin XI that reduce growth and branching and have strong asymmetric division defects. Making the mutant version of the protein is worse than no protein — first author @zebosi.bsky.social 🌽🎉

🤩 BEAUTIFULL highlight of our work by Sabine Muller now published in @currentbiology.bsky.social

Amazing study from Jill Anderson, Megan Demarche and colleagues, integrating species distribution models, reciprocal transplants, snow manipulation and more to test whether a montane plant can adapt to climate change. The sad answer: not without human intervention.

I had some absolutely incredible papers come online this week, and I need to take a minute to post about each of them. First, let me tell you about the CarboTag probes for imaging plant cell walls! From the Sprakel lab (a short thread) www.nature.com/articles/s41...

The Building Blocks of Early Land Plants: Glycosyltransferases and Cell Wall Architecture in the model liverwort Marchantia polymorpha https://www.biorxiv.org/content/10.1101/2025.04.30.651426v1

The Camelot paper is now published. If you ever wanted to try biomechanics, Camelot is an inexpensive and easy way to get started. @matmajda.bsky.social

🌱 When a root cell undergoes symmetric division, are the daughter cells actually identical? By combining live-cell imaging and scRNAseq we discovered a new cell state with uneven BR activity. Read our full paper in Cell: doi.org/10.1016/j.ce... @nvukas.bsky.social @trevormnolan.bsky.social

Just out in Cell @cellpress.bsky.social. Amazing collaboration with @flowerwhatelse.bsky.social, Renaud Dumas, Matias Zurbriggen, Ken Birnbaum and François Roudier. And spearheaded by two amazing scientists: Raquel Martin-Arevalillo and Bruno Guillotin
