Smell plays an important role in our lives: It influences the way in which we choose fruit and vegetables, perfume, and even a partner. And yet, smell is not just what we smell with our noses, it's also what we taste, explains Prof. Alexander Vainstein, who is heading the team at the Robert H. Smith Faculty of Agriculture, Food and Environment at the Hebrew University of Jerusalem. "Aroma is of major importance for defining the taste of food."
Scent in flowers and plants is used to attract pollinating insects like bees and beetles that pass on the pollen and help in the reproduction and creation of fruit. The intensity of the scent that the flower emanates is influenced by the time of day, depending on weather, age of the flower and the species.
Now Vainstein and others have found a way to genetically enhance the scent of flowers and implant a scent in those that don't have one.
