Preferred crystallographic orientation of cellulose in plant primary cell walls
Cellulose is synthesized as microfibrils of β-1,4-linked glucan chains arranged in a crystalline lattice. Here Ye et al. use grazing incidence wide angle X-ray scattering to show that cellulose crystals are preferentially orientated parallel to the plant

Summary: Extracellular matrices contain fibril-like polymers often organized in parallel arrays. Although their role in morphogenesis has been long recognized, it remains unclear how the subcellular control of fibril synthesis translates into organ shape.

Spatial relationships between polymers in Sitka spruce: proton spin-diffusion studies [PDF]
The spatial arrangement of polymers in Sitka spruce (Picea sitchensis) was investigated by NMR proton spin-diffusion studies, supplemented by deuterium-exchange experiments monitored by FTIR spectroscopy.

THE SIZE OF THE CELLULOSE MICROFIBRIL [PDF]
Recently the lateral width of the cellulose microfibril has been estimated as 30 A rather than about 150 to 200 A, by extrapolation of data from model shadowing experiments. The difference was attributed to a layer of metal deposited during shadowing.

Cell proliferation, cell shape, and microtubule and cellulose microfibril organization of tobacco BY-2 cells are not altered by exposure to near weightlessness in space [PDF]
The microtubule cytoskeleton and the cell wall both play key roles in plant cell growth and division, determining the plant’s final stature. At near weightlessness, tubulin polymerizes into microtubules in vitro, but these microtubules do not self ...

Probing the molecular architecture of Arabidopsis thaliana secondary cell walls using two- and three-dimensional 13C solid state nuclear magnetic resonance spectroscopy [PDF]
The plant secondary cell wall is a thickened polysaccharide and phenolic structure, providing mechanical strength to cells, particularly in woody tissues. It is the main feedstock for the developing bioenergy and green chemistry industries.

Cellulose synthase complex organization and cellulose microfibril structure [PDF]
Cellulose consists of linear chains of β-1,4-linked glucose units, which are synthesized by the cellulose synthase complex (CSC). In plants, these chains associate in an ordered manner to form the cellulose microfibrils. Both the CSC and the local environment in which the individual chains coalesce to form the cellulose microfibril ...

Manufacturing Of Robust Natural Fiber Preforms Utilizing Bacterial Cellulose as Binder [PDF]
We present a novel method of manufacturing rigid and robust short natural fiber preforms using a papermaking process. Bacterial cellulose acts simultaneously as the binder for the loose fibers and provides rigidity to the fiber preforms.

Diffraction evidence for the structure of cellulose microfibrils in bamboo, a model for grass and cereal celluloses. [PDF]
Background: Cellulose from grasses and cereals makes up much of the potential raw material for biofuel production. It is not clear if cellulose microfibrils from grasses and cereals differ in structure from those of other plants.

Folding of xylan onto cellulose fibrils in plant cell walls revealed by solid-state NMR
The polysaccharide xylan binds to cellulose microfibrils in the plant cell wall, but the nature of this interaction remains unclear. Here Simmonset al.
