Cellulose orientation determines mechanical anisotropy in onion epidermis cell walls.

The role of cellulose microfibril orientation in determining cell wall mechanical anisotropy and in the control of the wall plastic versus elastic properties was studied in the adaxial epidermis of onion bulb scales using the constant-load (creep) test. The mean or net cellulose orientation in the outer periclinal wall of the epidermis was parallel to the long axis of the cells. In vitro cell w...

Roles of cellulose and xyloglucan in determining the mechanical properties of primary plant cell walls

The primary cell walls of growing and fleshy plant tissue mostly share a common set of molecular components, cellulose, xyloglucan (XyG), and pectin, that are required for both inherent strength and the ability to respond to cell expansion during growth. To probe molecular mechanisms underlying material properties, cell walls and analog composites from Acetobacter xylinus have been measured und...

Structure of cellulose microfibrils in primary cell walls from collenchyma.

In the primary walls of growing plant cells, the glucose polymer cellulose is assembled into long microfibrils a few nanometers in diameter. The rigidity and orientation of these microfibrils control cell expansion; therefore, cellulose synthesis is a key factor in the growth and morphogenesis of plants. Celery (Apium graveolens) collenchyma is a useful model system for the study of primary wal...

Tools for cellulose analysis in plant cell walls.

Cellulose is intimately associated with multiple facets of human civilization: central to clothing, shelter, heat, medicine, and food, there are fewmoments in the average human life that are not spent in direct contact with cellulose or a by-product of its composition. It should come as no surprise then that a considerable amount of time and energy have been spent, and a couple of Nobel Prizes ...

Solid-state NMR investigations of cellulose structure and interactions with matrix polysaccharides in plant primary cell walls.

Until recently, the 3D architecture of plant cell walls was poorly understood due to the lack of high-resolution techniques for characterizing the molecular structure, dynamics, and intermolecular interactions of the wall polysaccharides in these insoluble biomolecular mixtures. We introduced multidimensional solid-state NMR (SSNMR) spectroscopy, coupled with (13)C labelling of whole plants, to...
