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 ...

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 ...

Researchers have discovered a widespread mechanism in bacteria that enhances the bacteria's defense against environmental threats. The discovery, which may be important for research into developing ...

A new method developed by Penn State biologists allows them to turn stripped-down plant cells into other types of cells, similar to the way stem cells differentiate into different cell types. Using ...

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 ...
