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 ...

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

A plant cell wall is arranged in layers and contains cellulose microfibrils, hemicellulose, pectin, lignin, and soluble protein. These components are organized into three major layers: the primary ...

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 ...

Plant cell walls incorporate a variety of acetylated polysaccharides. In addition to enzymes catalysing acetylation (acetyltransferases), plants could produce enzymes to remove acetyl groups ...

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 ...

A new method developed by Penn State biologists allows them to turn stripped-down plant cells into other types of cells, ...
