In COST Action PlantWallK (CA24116), we connect cytoskeleton dynamics with cell wall organisation and mechanics, across species and methods. Linking inside–outside helps explain how form emerges.

Satellite meeting: European Plant Cytoskeletal Club (EPCC) 2026 – Prague, 26–27 May
🎟 EPCC is free of charge but not funded by COST Action CA24116 - PlantWallK.
PlantWallK members funded for 25–26 May will be reimbursed only for those days.
📝 Abstract deadline: 15 April 2026

✔ Daily allowance: up to 196 EUR
✔ Travel costs: up to 1200 EUR
✔ About 40 participants expected to be funded
Selected speakers will receive an official e-COST invitation before the meeting.

💶 Travel support is available for members of COST Action CA24116 - PlantWallK. Reimbursement will be awarded based on abstract quality and relevance to the Action goals, as described here: e-services.cost.eu/files/domain...

Through PlantWallK (CA24116), root studies are connected with work in other organs and species to build shared understanding of wall function.

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.

Within COST Action PlantWallK (CA24116), such wall diversity is studied across species and organs to link structure, mechanics, and biology.

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.

PlantWallK (CA24116) connects researchers studying plant cell walls across species, scales, and methods, enabling comparison and shared frameworks.

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.
