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 ...

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 ...

For a bacterial cell, the cell-wall is vital in determining the shape of the cell and to maintain its structural integrity. This is a unique feature of bacterial cells, and several antibiotics work by ...

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 ...

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 ...

The bacterial cell wall must be constantly remodeled in order to grow and divide. This involves the close coordination of lytic enzymes and peptidoglycan synthesis. Researchers led by Martin ...

New research has demonstrated that extracts from plant cell walls can be used to develop sustainable treatments to protect against crop diseases. Crop diseases can be completely devastating in ...

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 ...
