COVER In roses (Rosa x hybrida), scent is a highly desirable trait. Monoterpenes are the major rose scent compounds, representing up to 70% of the fragrance content in some varieties. Combined transcriptomic and genetic approaches show that monoterpene biosynthesis in roses differs from what is known in other plants and involves a specialized Nudix hydrolase protein localized in the cytoplasm of rose petal cells.
