Genetic dissection of plant cell-wall biosynthesis.
The plant cell wall is a complex structure consisting of a variety of polymers including cellulose, xyloglucan, xylan and polygalacturonan. Biochemical and genetic analysis has made it possible to clone genes encoding cellulose synthases (CesA). A comparison of the predicted protein sequences in the Arabidopsis genome indicates that 30 divergent genes with similarity to CesAs exist. It is possi...
متن کاملUpdate on Storage Cell Wall Biosynthesis and Degradation Seed Cell Wall Storage Polysaccharides: Models to Understand Cell Wall Biosynthesis and Degradation
Cell wall storage polysaccharides (CWSPs) are found as the principal storage compounds in seeds of many taxonomically important groups of plants. These groups developed extremely efficient biochemical mechanisms to disassemble cell walls and use the products of hydrolysis for growth. To accumulate these storage polymers, developing seeds also contain relatively high activities of noncellulosic ...
متن کاملThe structure, function, and biosynthesis of plant cell wall pectic polysaccharides.
Plant cell walls consist of carbohydrate, protein, and aromatic compounds and are essential to the proper growth and development of plants. The carbohydrate components make up approximately 90% of the primary wall, and are critical to wall function. There is a diversity of polysaccharides that make up the wall and that are classified as one of three types: cellulose, hemicellulose, or pectin. T...
متن کاملInteractions between MUR10/CesA7-dependent secondary cellulose biosynthesis and primary cell wall structure.
Primary cell walls are deposited and remodeled during cell division and expansion. Secondary cell walls are deposited in specialized cells after the expansion phase. It is presently unknown whether and how these processes are interrelated. The Arabidopsis (Arabidopsis thaliana) MUR10 gene is required for normal primary cell wall carbohydrate composition in mature leaves as well as for normal pl...
