The key ingredients of the scent of roses are the result of an original and unexpected biosynthetic pathway that had never been studied before in plants. Such are the findings of researchers at the ENS Lyon Laboratory for Reproduction and Development of Plants
(RDP), working together with scientists from the University Jean Monnet in Saint-Etienne, the Universities of Lyon and Strasbourg and the CNRS.
The team identified an enzyme known as RhNUDX1, which plays a key role in producing the sweet fragrance of roses. These findings, published in Science
on July 3, could ultimately help breeders develop roses with more powerful scents. In recent years, rose breeding had largely focused on traits like colour and longevity at the expense of fragrance.
