Do you want to know how to build an organ from a single cell?

Check out our paper about phyllid development in moss by Weney Lin @irbv.bsky.social

Colaboration with Yoan Couder @ensdelyon.bsky.social and and Richard Smith @johninnescentre.bsky.social

The final version of our Marchantia cell cycle paper is now published. A much improved version compared to the preprint. Cyclins, repressors, and more. Thanks to co-authors and reviewers. #PlantScience. academic.oup.com/plcell/advan...

Excited to share what we learned about Katanin in maize www.nature.com/articles/s41... 🧪

Our new experimental evolution study across 30+ locations using the plant Arabidopsis thaliana —— we direct "see" adaptation and extinction to different climates at the genetic as it happens!

Read it in Science

Very excited that our review on carbon allocation to axial sink organs is published. Super writing experience and discussions with Anil and @bjazminrh.bsky.social, thank you both for your great work and ideas!

What features are required to shape hypoxic niches enclosing meristems? We @viktoriiavoloboeva.bsky.social in collab @pieterverboven.bsky.social found that a combination of cuticle barrier, densely packed tissue and metabolic activity all uniquely contribute to maintain shoot apical meristem hypoxia

Immune activation suppresses reproductive growth in Arabidopsis through cytokinin signaling Johnston et al. report that defense hormones suppress cytokinin signaling, causing yield penalties. Restoring cytokinin in autoimmune plants relieves reproductive defects, confers broad pathogen resis...

Our beautiful work is out in Current Biology! @currentbiology.bsky.social

Does hidden protein biology live in the suboptimal alignment space?

When we align two divergent proteins, we usually trust a single optimal alignment. 🧬

But what if the real structural signal lies in the space of near-optimal solutions?

With EMERALD-UI you can unfold this perspective.

The actin cytoskeleton is required to maintain plant cell division orientation against cellular geometry Actin guides plant cell division, shaping tissues in ways that defy geometric constraints.

What a treat to see the work from Camila Goldy @camilagoldy.bsky.social et al., @rdplab.bsky.social @ensdelyon.bsky.social now published 🫶

Cool story from @meristemania.bsky.social lab on growth-defense tradeoff at the shoot apical meristem www.biorxiv.org/content/10.6...

Thank you Arif for the highlight!

Excited to share our latest review on hydrosignaling: moisture-dependent molecular pathways that help plants grow towards water. Insightful review of the literature and discussion of moisture sensing mechanisms by Will Dwyer and @hhtormar.bsky.social. Enjoy!

Evolution and development: What makes a merry stem? From tiny mosses to giant redwoods, around 450,000 species of land plants show a huge variety of forms, yet all land plants develop from stem cells in proliferative meristems. What makes a meristem? T...

It was good to catch up on my reading for this dispatch in Current Biology. Sjoerd Woudenberg in the Weijers lab, Wallner et al. In the Dolan lab and Flores Sandoval et al. In the Bowman lab have done a great job! Evolution and development: What makes a merry stem?: www.cell.com/current-biol...

Plants and animals evolve radically different body plans.

Do they also operate under fundamentally different molecular evolutionary constraints during organ formation?

At the end of 2024 I did a chronological round up of all the #plantscience in @science.org that year.
So how did 2025 pan out? This year, I’m grouping papers thematically instead of chronologically so read on to find out what exciting plant science came out over the last 12 months. (1/22)

Left: the shoot apex of an Arabidopsis thaliana plant. Right: the shoot apical meristem. Actively dividing stem cells are shown in green, and the cell walls are labelled in magenta.

Congratulations to researchers from the CAS-JIC-TSL Centre of Excellence for Plant and Microbial Science (CEPAMS) who have revealed a novel mechanism that controls plant stem cell dynamics through precise spatial patterning of cell wall modification.

Did you ever wonder how a dividing cambium cell looks like and what determines its striking regular division? Xiomin Liu, PhD student in the lab, found out in a heroic histological approach. Fruitful collaboration with the group of Sabine Müller (@phragmoplast.bsky.social) doi.org/10.64898/202...

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"
