Primary and Secondary Plant Cell Walls: a Comparative Overview*
نویسنده
چکیده
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 on wall type and plant taxon. The non-cellulosic polysaccharide compositions of three common wall types — lignified secondary walls, non-lignified secondary walls, and non-lignified primary walls — exemplify this. The principles used in constructing the most recent models of non-lignified primary walls can be used in modelling lignified secondary walls.

Comparative structure and biomechanics of plant primary and secondary cell walls
Recent insights into the physical biology of plant cell walls are reviewed, summarizing the essential differences between primary and secondary cell walls and identifying crucial gaps in our knowledge of their structure and biomechanics. Unexpected parallels are identified between the mechanism of expansion of primary cell walls during growth and the mechanisms by which hydrated wood deforms un...

A brief overview of the structure of mannans in plant cell walls and other organisms is presented. In particular, mannans, galactomannans and glucomannans in seed endosperm and vegetative tissues such as bulbs and tubers, galactoglucomannans (GGMs) in primary cell walls, and glucomannans and GGMs in secondary walls of hardwoods and softwoods are covered. Possible roles of mannans in primary pla...
متن کاملPlant cell walls.
Cell walls are important features of plant cells that perform a number of essential functions, including providing shape to the many different cell types needed to form the tissues and organs of a plant. Forming the interface between adjacent cells, plant cell walls often play important roles in intercellular communication. Because of their surface location, plant cell walls play an important r...

متن کاملPlant cell walls and cell-wall polysaccharides: structures, properties and uses in food products
We describe preparations of plant cell walls and polysaccharides obtained from plant cell walls that are added to food products for two purposes: as modifiers of food texture and/or as dietary fibres with potential health benefits. Although a number of different types of plant cell walls occur, only some are presently exploited. Commercial ‘fibre preparations’ range from those containing mostly...
