For the first time, high-resolution time-lapse videos of tiny bits of living plants show how they assemble their protective cell walls, researchers report March 21 in Science Advances. The image ...

Plant cells are surrounded by an intricately structured protective coat called the cell wall. It’s built of cellulose microfibrils intertwined with polysaccharides like hemicellulose or pectin. We ...

How cells sense their physical state and compensate for cell wall damage is poorly understood. But a new analysis of plants exposed to salt stress offers the first experimental evidence and molecular ...

The composition of an organism’s cell wall is the fourth characteristic used to classify an alga. Diatoms are unique as their cell wall is made of silica. The intricate designs within their silica ...

Using a new method to isolate and reprogram plant cells into other cell types, biologists explored how banding patterns that increase the stability of plant cell walls are created and how their ...

Imagine if our bodies could grow new organs throughout our entire lives. Plants do this constantly, thanks to the tiny, powerful reservoirs of stem cells. But how do these cells know when to divide, ...

Banding patterns of cellulose increase the stability of plant cell walls, much like the corrugated patterns in cardboard. Penn State biologists developed a method to isolate plant cells and observe ...
