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 ...

Scientists have discovered new filamentous structures within plant cell walls that influence cell growth and help build complex three-dimensional cell shapes. Scientists have discovered new ...

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 ...

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 ...

The secret of how fiber shapes the structure of plant cell walls has been revealed, with potentially wide-ranging applications ranging from nutrition and health to agriculture. Researchers from The ...

UNIVERSITY PARK, Pa. -- A plant cell wall's unique ability to expand without weakening or breaking--a quality required for plant growth--is due to the movement of its cellulose skeleton, according to ...

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, ...

Plant cell walls have a special ability to expand without breaking or weakening, which is crucial for plant growth. New research has shown that the cellulose skeleton of the plant cell wall is what ...

Professor Bo Liu, Department of Plant Biology, holds an Arabidopsis plant while Professor Jawdat Al-Bassam, Department of Molecular and Cellular Biology, holds a model of the augmin protein complex.

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

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 ...
