ABSTRACT
The mixed-linkage (1[arrow right]3),(1[arrow right]4)-[beta]-D-glucans are unique to the Poales, the taxonomic order that includes the cereal grasses. (1[arrow right]3), (1[arrow right]4)-[beta]-Glucans are the principal molecules associated with cellulose microfibrils during cell
growth, and they are enzymatically hydrolyzed to a large extent once growth has ceased. They appear again during the developmental of the endosperm cell wall and maternal tissues surrounding them. The roles of (1[arrow right]3),(1[arrow right]4)-[beta]-glucans in cell wall architecture and in cell growth are beginning to be understood. From biochemical experiments with active synthases in isolated Golgi ...
