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 asthe Papa Meilland rose. Monoterpene biosynthesis in plants relies on plastid-localizedterpene synthases. Combining transcriptomic and genetic approaches, we show thatthe Nudix hydrolase RhNUDX1, localized in the cytoplasm, is part of a pathway for thebiosynthesis of free monoterpene alcohols that contribute to fragrance in roses. TheRhNUDX1 protein shows geranyl diphosphate diphosphohydrolase activity in vitro andsupports geraniol biosynthesis in planta.

International audience. Roses use a non-canonical pathway involving a Nudix hydrolase, RhNUDX1, to synthesize their monoterpe-nes, especially geraniol. Here we report the characterization of another expressed NUDX1 ...
