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 #COSTAction #PlantCellWall #PlantScience
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: An Arabidopsis root tip with cell walls highlighted using a pectin probe. Different tissues show distinct signals, reflecting how cell wall composition changes as cells divide, grow, and specialise.
#PlantWallK #COSTAction #PlantCellWall #PlantScience
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.
