Arabidopsis primary cell walls
Plant cell wall (CW) polysaccharides are responsible for the mechanical strength and growth of plant cells; however, the high-resolution structure and dynamics of the CW polysaccharides are still poorly understood because of the insoluble nature of these molecules. Here, we use 2D and 3D magic-angle-spinning (MAS) solid-state NMR (SSNMR) to investigate the structural role of pectins in the plan...
متن کاملRole of xyloglucan in primary cell walls.
The plant cell wall is a highly complex and dynamic structure made up of cellulose, hemicelluloses, pectins, lignin, and numerous proteins and inorganic molecules (Carpita and McCann, 2000). The hemicellulose xyloglucan (XyG) is found in the cell walls of all vascular plants and is the major hemicellulose in the primary cell wall of eudicots and nongraminaceous monocots, where it is believed to...
متن کاملStructure 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...
متن کاملChemical Constitution of the Primary Cell Walls of Avena Coleoptiles.
In studies of the structure and development of primary walls of plant cells, little detailed attention has been given to the non-cellulosic components of the wall. Indeed, as Bonner (6, p. 130) has indicated, only rarely have thorough analyses of plant walls of any type been made. For the most part, characterization of wall constituents has depended on solubility properties and staining tests, ...
متن کاملPrimary and Secondary Plant Cell Walls: a Comparative Overview*
Light and transmission electron microscopy are used in studying wall morphology and histochemical methods, including immunocytochemistry, can be used to locate specific compounds in walls. All plant cell walls contain a fibrillar phase of cellulose microfibrils and a matrix phase which contains a high proportion of non-cellulosic polysaccharides that vary in their chemical structures, depending...
