Lignocellulose Structure News Today

Cellulose -; an integral component of plant cell walls -; is an important source of food, paper, textiles and biofuels, but how its creation is regulated within plant cells has remained unclear.

A plant cell wall’s unique ability to expand without weakening or breaking is due the movement of its cellulose skeleton, according to new research by Penn State biologists that models the cell wall. Chains of cellulose bundle together within the cell wall, providing strength, and slide against each other when the cell is stretched, providing extensibility.

Newswise — UNIVERSITY PARK, Pa. — A multi-institutional research group led by two Penn State faculty members has identified, for the first time, how cellulose crystals orient themselves relative to the cell wall in plants, with potential implications for chemical...
