Abstract
The aim of the project is to use solid-state NMR relaxation experiments as a link between the mechanical properties of fruit and vegetable cell walls - determinants of textural quality - and the structure of the cell wall polysaccharides. Three biological systems will be used: 1. Ripening transgenic tomato fruit containing antisense genes to downregulate polygalacturonase and pectinesterase; 2. Potato tubers; 3. Onions. The onion and potato cell walls will be degraded by beta-elimination of pectins during normal cooking conditions. NMR relaxation data and measurements of the nuclear Overhauser effect made by a novel solid-state technique, will be used to define the primary polymer chains that become looser on ripening or cooking, and to find out how this allows other structural elements of the cell wall to become more flexible.
