Arabidopsis is the current model for plant genomic and development research. The Arabidopsis is behind the current form of biochemical and structural analyses. The availability of the genome provides alternative and a first approach look at the identification of some interesting genes. These enzymes add monosaccharaides to specific spots on accept molecules to make monosaccharaides into linear or branched sugar chains. Glycosyltransferase seem to appear in large numbers in higher eukaryotes than in lower eukaryotes. Processive Glycosyltransferase add a sugar molecule to the end of a linear polysaccharide without the acceptor substrate. The type of family they are put into is determined by the type of sugar that they transfer and the linkage they establish. The cell walls of plants play

Unformatted text preview: a crucial role in development, signal transduction, and response to environmental factors, including microbial pathogens and insects. The most known hemicellulose of primary plant cell walls is the Xyloglucan (XG). XGs job is to bind and cross-link cellulose microfibrils. That basically means that XG is in control of cell growth of the cell wall. Several legumes like guar and fenugreek deposit galactomannans as storage polysaccharides. Plants possess both N and O glycans and the ighway top the N-glycans is very conserved. In the end cell wall biosynthesis is very important to the understanding of plant development. This interest is spreading due to the increasing evidence that cell wall mediate cellular interactions....
