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 ...

Plant meristems represent specialised tissues housing pluripotent stem cells that underpin continuous growth and organ formation. The intricate regulation of these stem cells is mediated by a complex ...

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) Examples of medicinal plants and their meristematic tissues as sources for stem cell generation. (b) Advantages of using medicinal plant stem cells in research and industrial applications. (c) In ...

At first glance, plant and animal cells have a lot in common: they’re both highly organized, keep their DNA tucked away in an envelope, and are kinda juicy inside. But plant cells have evolved some ...

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 the tiny, beaded chain of the cyanobacterium Anabaena sp. ATCC 33047, two different cells, the photosynthetic factory worker and the nitrogen-fixing specialist, play distinct and powerful roles in ...

For the first time, high-resolution time-lapse videos of tiny bits of living plants show how they assemble their protective cell walls, researchers report March 21 in Science Advances. The image ...
