Metabolic engineering of the volatile spectrum offers enormous potential for plant improvement because of the great contribution of volatile secondary metabolites to reproduction, defense and food quality. Recent advances in the identification of the genes and enzymes responsible for the biosynthesis of volatile compounds have made this metabolic engineering highly feasible. Notable successes have been reported in enhancing plant defenses and improving scent and aroma quality of flowers and fruits. These studies have also revealed challenges and limitations which will be likely surmounted as our understanding of plant volatile network improves.
