    Description: The scent of roses (Rosa x hybrida) is composed of hundreds of volatile molecules. Monoterpenes represent up to 70% percent of the scent content in some cultivars, such as the Papa Meilland rose. Monoterpene biosynthesis in plants relies on plastid-localized terpene synthases. Combining transcriptomic and genetic approaches, we show that the Nudix hydrolase RhNUDX1, localized in the cytoplasm, is part of a pathway for the biosynthesis of free monoterpene alcohols that contribute to fragrance in roses. The RhNUDX1 protein shows geranyl diphosphate diphosphohydrolase activity in vitro and supports geraniol biosynthesis in planta.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Magnard, Jean-Louis -- Roccia, Aymeric -- Caissard, Jean-Claude -- Vergne, Philippe -- Sun, Pulu -- Hecquet, Romain -- Dubois, Annick -- Hibrand-Saint Oyant, Laurence -- Jullien, Frederic -- Nicole, Florence -- Raymond, Olivier -- Huguet, Stephanie -- Baltenweck, Raymonde -- Meyer, Sophie -- Claudel, Patricia -- Jeauffre, Julien -- Rohmer, Michel -- Foucher, Fabrice -- Hugueney, Philippe -- Bendahmane, Mohammed -- Baudino, Sylvie -- New York, N.Y. -- Science. 2015 Jul 3;349(6243):81-3. doi: 10.1126/science.aab0696.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratoire BVpam, EA3061, Universite de Lyon/Saint-Etienne, 23 Rue du Dr Michelon, F-42000, Saint-Etienne, France. ; Laboratoire BVpam, EA3061, Universite de Lyon/Saint-Etienne, 23 Rue du Dr Michelon, F-42000, Saint-Etienne, France.
