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 tiny, powerful reservoirs of stem cells. But how do these cells know when to divide, and ...

Biomechanics reveals cell wall age properties and how newly born cells can change their local shape and influence the growth of plant organs Scientists reveal new plant cell walls can have ...

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 ...

In a groundbreaking study on the synthesis of cellulose -- a major constituent of all plant cell walls -- a team has captured images of the microscopic process of cell-wall building continuously over ...

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 ...
