Why do primary plant tissues hold their shape? We are told it's because of turgor pressure—but how does that work mechanically? We investigated how pressurized cylindrical structures support themselves. Read here: doi.org/10.1039/d6sm... Funded by @hfspo.bsky.social www.plantbiomechanics.net

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

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.

What a treat to see the work from Camila Goldy @camilagoldy.bsky.social et al., @rdplab.bsky.social @ensdelyon.bsky.social now published 🫶 www.science.org/doi/10.1126/...

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.

🧵 Just out in Cell after more than 10 years in the making! 🎓 www.cell.com/cell/fulltex... Plants and animals evolve radically different body plans. Do they also operate under fundamentally different molecular evolutionary constraints during organ formation? @cellpress.bsky.social

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)

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: www.upsc.se/juan_alonso_... #PlantSciences

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/...
