Introduction Plant cell wall ü Strenghtens the plant body, but has also key roles in plant growth, cell differentiation, intercellulair communication, water movement and defence ü A complex polysaccharide wall which constitutes the raw material that is used to manufacture textiles, paper, films, thickeners and other products ü Primary source of cellulose, the most abundant biopolymer on the Earth ü Interesting composite material How is it made? How is it broken down?

Introduction Outline ü Plant cell wall composition, primary cell wall, secondairy cell wall Intermezzo 1: Structure of the main polysaccharides that are present in the plant cell wall ü How do plant cells synthesize wall polysaccharides? Biosynthesis of cellulose and matrix polysaccharides How is a strong fibrous network assembled? Physico-chemical interactions and enzymatic crosslinking What about wall expansion during cell growth? Enzymes involved in this process
