Microscopy image of a pea root apex. The root tip shows a clear growth zone with orderly layers of cells arranged in files. Cell outlines form a regular, brick-like pattern that changes gradually from small, densely packed cells near the tip to larger, elongated cells further back. The tissue organisation of the root is visible as distinct regions with different cell sizes and orientations.

Close up of a microscopy image of a pea root apex. The root tip shows a clear growth zone with orderly layers of cells arranged in files. Cell outlines form a regular, brick-like pattern that changes gradually from small, densely packed cells near the tip to larger, elongated cells further back. The tissue organisation of the root is visible as distinct regions with different cell sizes and orientations.

Picture of the day: Pea root apex with orderly cell layers and active growth zones. Roots are key systems to study how cell walls support division and expansion.

Cross section of a Brachypodium stem seen under the microscope. The stem forms a roughly circular ring of tissues. Some regions show thick, strongly stained cell walls forming supportive tissue, while other regions show thinner-walled cells. The contrast between thick- and thin-walled areas makes the functional zoning of the stem easy to see.

Picture of the day: Cross section of a Brachypodium stem. Thick supporting tissues contrast with thinner growing regions, showing how cell wall structure is tuned to function.

This image shows an Arabidopsis root tip, with cell walls highlighted by a pectin probe. Differences in signal across tissues reflect changes in wall composition and organisation as cells divide, expand, and differentiate. At this scale, mechanics, chemistry, and development meet. One of the goals of COST Action PlantWallK (CA24116) is to connect observations like this across species, methods, and scales. By sharing tools, data, and concepts, we aim to build a common framework for plant cell wall mechanobiology.

More cool #Lignin and #PlantCellWall suff from @icesarino.bsky.social et al.

Great work by Chaudhary et al. (2025) on how #FERONIA (FER), a cell wall integrity sensor, is essential for limiting #PlantCellWall damage and preventing cell rupture during #brassinosteroid (BR)-induced cell elongation in #Arabidopsis.
BR signaling promotes FER accumulation at the plasma membrane.

Diagrams illustrating how the transcription factor MYB61 positively regulates the expression of the mannan synthase gene STRONG2, thus affecting cell wall composition, promoting secondary cell wall formation, and enhancing lodging resistance.

🌾 Staying strong––no matter the weather!🍃
Zhao et al. reveal their recent findings on how MYB61 activates expression of the mannan synthase gene CSLA5 and thus increases culm strength in #rice.

Hello world!🌱 Our lab at Umeå Plant Science Centre (Sweden) and NTNU (Norway) explores how plants and algae actively perceive and adapt through their cell walls. Growth, defence, and resilience all start here! Follow us for updates on our research #PlantScience #CellWalls #PlantCellWall #AcademicSky

Here’s Nancy Soni proudly presenting her award-winning poster on the interplay between cell wall integrity and cell cycle dynamics in plant biology at the Scandinavian Plant Physiology Society Meeting in Copenhagen!

Very proud of Nancy Soni, postdoc in the team, for winning the Best Poster Award at the SPPS Meeting in Copenhagen! Her hard work in our Wall2Cycle project, which investigates #PlantCellWall homeostasis in cell cycle progression, is truly deserving of this recognition. CONGRATULATIONS!!!

Debora Gasperini and Tonni Grube Andersen on stage at the MPIPZ. The cover slide of Debora's talk states the title "Integrating osmotic potential with Jasmonate-mediated plant acclimation".

Another really cool Wednesday-Seminar here at the MPIPZ. This week @tonnigrube.bsky.social hosted Debora Gasperini from the Leibniz Institute IPB in Halle. Great talk on how #PlantCellWall properties influence #Phytohormone signaling and long-distance biotic stress responses.

Sabrina Sabatini on stage in the lecture hall of the Max Planck Institute for Plant Breeding Research in Cologne. On the screen behind her are examples of organ formation, showing a human heart and an emerging lateral plant root.

(Only) once per year, the PhD students at MPIPZ Cologne get to select a speaker for the weekly Guest Seminar. They delivered a #PlantScience legend. Sabrina Sabatini spoke about how #PlantCellWall mechanics need to be altered to allow for cells to transition from the meristem toward differentiation.

Exciting news! My research group at @UmeaPlantSci is seeking a highly motivated PhD student to join our team and investigate the dynamic behavior of plant cell walls. Apply now to become part of our cutting-edge research program! #PhDposition #PlantScience #PlantCellWall
