A new tool to study plant cell biomechanics

We know that within every living plant there are millions of cells working together in a wonderfully complex harmony. But what we don't know is, within each of these cells, what exactly is going on....

Enzyme shows promise for efficiently converting plant biomass to biofuels

To make biofuels, tiny microbes can be used to break down plant cells. As part of that digestive process, specialized enzymes break down cellulose—a major molecule that makes plant cell walls rigid....

Plant cell walls' stretch-but-don't-break growth more complex than once thought

Plant cell wall growth is typically described as a simple process, but researchers using a microscope that can resolve images on the nanoscale level have observed something more complex.

A better dye job for roots—in plants

Once we start coloring our hair, we may be surprised to learn that we begin to have a problem in common with plant biologists: finding the right dye for our roots. In the case of the biologists, just...

Why plants form sprouts in the dark

A signal from the cell wall decides that, in the dark, seeds grow into long yellow sprouts, instead of turning green and forming leaves. The signal that switches on the darkness programme in seedling...
