Cellulase, Polygalacturonase and β-galactosidase Activity in Ripening Raspberry (Rubus caesius L.) fruit
Journal Title: Scholars Academic Journal of Biosciences - Year 2014, Vol 2, Issue 3
Abstract
Activities of the cell wall degrading enzymes cellulase, polygalacturonase, and β-galactosidase were determined on unripe, semi-ripe, and ripe raspberry (Rubus caesius L.) fruit. The enzyme activity, measured as µmoles of released product.g-1 of fruit h-1 indicated the presence of polygalacturonase, cellulose, and β-galactosidase in raspberry fruit. Enhanced fruit ripening was reflected by increased values for cellulase, polygalacturonase abd β- galactosidase activity. In raspberry cellulose, polygalacturonase, and βgalactosidase appear to be involved in fruit softening during unripe to the ripe stages. Keywords: Raspberry, Fruit ripening, Cellulase, Polygalacturonase, β-galactosidase
