Abstract

Beta-galactosidase is an enzyme found in most fruit tissues where its action would be expected to have effects on cell wall metabolism, fruit texture and paste quality. The enzyme exists in at least three isoforms and one of these, an exo acting beta (1-4) galactanase has been purified and characterised. Transgenic plants in which expression of this galactanese gene has been down regulated by co-suppression have been produced. This project will characterise these transgenic fruit in terms of cell wall structure and rheological properties. The other isoforms will be characterised and transgenic plants produced in which these activities have been modified. These plants will be used to examine the role of beta-galactosidase in determining cell wall structure and fruit ripening and may lead to commercially exploitable material.
