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 ...

Plant cell walls, composed primarily of cellulose, hemicellulose and pectins, serve as dynamic structures that not only provide mechanical strength and protection but also regulate growth, ...

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 ...

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 ...

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 ...

Mesophyll conductance, or the ease with which CO 2 can diffuse through a leaf’s cells before reaching the location where it undergoes carbon fixation, plays a key role in photosynthesis. CO 2 faces ...

Petal size is a defining trait of ornamental flowers, directly shaping visual appeal and commercial value. A new study uncovers how petal expansion in roses is precisely regulated through a feedback ...

A study provides new clues in the understanding of how antibiotic resistance spreads. The study shows how an enzyme breaks down the bacteria's protective outer layer, the cell wall, and thus ...

Fungi are everywhere, and in many cases, a fungal infection can be eliminated by a person's immune system. But fungal infections can also send long hyphae into the body that are extremely difficult to ...

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 ...
