Other research teams are working on lettuce that wilts more slowly, bruise-resistant apples and potatoes and identifying the genes that determine how quickly grapes and blueberries shrivel.
Pro tip: Buy your grapes, take them home, rinse them and promptly remove them from the vine. They will last up to a week in the fridge if the plant they grew on isn't desperately trying to stay alive longer with zero hope of survival by feeding on the grapes.
