Stone cells arise from lignified secondary cell walls and cause a gritty texture, reduced sweetness, and poor flavor in many pear cultivars. Traditional Pyrus ussuriensis varieties such as 'Nanguo' ...

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 ...

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 ...
