Abstract

Cell adhesion is the single most important factor determining food mechanical properties. Juiciness plant products reflecting strong cell wall contacts and therefore bursting of cells on first bite, while mealiness results from ready separation of cells in the tissue without cell breakage and juice release. The degree of cell separation therefore has a critical impact on texture, a critical quality discriminator for fruit and vegetable products. The proteins that control the degree of cell adhesion and softening in fleshy fruits, such as those regulating the relevant hydolytic enzymes, have so far eluded identification. The Cnr mutation in tomato results in ripe fruit where the pericarp cells remain colourless and show altered cell adhesion and texture properties. Revealing the normal function of the gene at the Cnr locus will provide a unique opportunity to dissect the molecular basis of cell adhesion and fruit texture. The key objectives of the project are to complete the cloning of the gene at the Cnr locus, establish whether the CNR gene has a generic role in cell separation in fruit bearing species and elucidate steps in the regulatory network linking CNR gene expression to cell separation and texture changes.
