Research interests and expertise:
Our primary focus is on identifying genes that influence starch and sucrose accumulation in crop plants. The level of these carbohydrates, their interconversion, and long-term storage, are central to crop yield, postharvest quality, and plant survival under abiotic stress. Therefore, genes that regulate these biomolecules may be good biotechnological targets for improving the sustainability of crop production. We also study postharvest chilling injury in tomato fruit, with a view to understanding the molecular basis of this disorder. This may help to develop practical solutions to reduce the severity of this disorder, and permit the use of a cold chain for the postharvest handling of tomato and other tropical and semitropical fruit that are sensitive to refrigeration.
