A Note on the Cell-Wall Structure of Softwood Tracheids
Keywords:Cell-wall models, cellulose, hemicellulose, lignin
AbstractMolecules of hemicellulose in walls of softwood tracheids are birefringent and lie essentially parallel to cellulose molecules. These hemicelluloses perform a structural function in providing a link between cellulose and lignin, and consequently should be considered as "coupling agents" between them. Models of the softwood tracheid cell wall should recognize this structural role for hemicelluloses.
