Uniform elementary fibrils in diverse plant cell walls.

ABSTRACT: Plant cell walls are composed of skeletal cellulose and a filling matrix of hemicelluloses and lignin. Cellulose has slender crystallite units referred to as microfibrils or elementary fibrils, and these crystallites form a dense network skeleton in the cell walls. In this study, we assessed the morphology and crystallinity of individually dispersed microfibrils isolated from the cell walls of wood, cotton, and ramie celluloses. It is well known that microfibrils in higher plants exhibit structural diversity, and these three plants, in particular, have distinct differences in the morphology and crystallinity of microfibrils. Our structural analyses combining atomic force microscopy (AFM), wide-angle X-ray diffraction (WAXD), small-angle X-ray scattering (SAXS), solid-state ¹³C N
