Abstract

Cell adhesion is important in maintaining firmness in fruits and vegetables. In plant cell walls, phenylpropanoids confer thermal stability of texture by enhancing cell adhesion. The work aims, by molecular-genetic means, to enhance cell adhesion of fresh and processed plant materials by increasing cell-wall phenylpropanoid cross-linking in the model species, tobacco. This will be carried out by increasing the levels of phenylpropanoids attached to the polysaccharides in the cell walls, and increasing the level of oxidant (hydrogen peroxide) for subsequent peroxidative cross-linking. Transgenic plants will be analysed for changes in mechanical properties before and after thermal treatment, cell-wall-phenolic chemistry and synthesis, and related changes in wound/disease response. (Joint with grants D11645, D11646 and D11648).
