A plant cell wall is arranged in layers and contains cellulose microfibrils, hemicellulose, pectin, lignin, and soluble protein. These components are organized into three major layers: the primary ...

Bacillus anthracis, the causative agent of anthrax, possesses a uniquely complex cell envelope that is critical to its pathogenicity. Central to its virulence are the secondary cell wall ...

The protein CSI1 and the alternating angle of the many layers that make up a cell's wall, creating a herringbone pattern (left), are critical for cell growth. The cell wall layers of a mutant plant ...

UNIVERSITY PARK, Pa. -- A plant cell wall's unique ability to expand without weakening or breaking--a quality required for plant growth--is due to the movement of its cellulose skeleton, according to ...

Plant cells tend to grow longer instead of wider due to the alignment of the many layers of cellulose that make up their cell walls, according to a new study that may have implications for biofuels ...
