| Research Abstract |
To obtain knowledge useful for the breeding of fragrant flowers, following experiments were conducted using cut roses. Emission of monoterpenes including citronellol, nerol and geraniol, sesquiterpenes, aromatic alcohols, acetate esters and 3,5-dimethoxytoluene were detected. The scent of these cut roses showed a sedative effect and decreased mental fatigue. In addition to these, tow monoterpene synthases, RhMTS1 and RhMTS2, were cloned. The ThMTS2 are grouped into a cluster consisting of acyclic monoterpene synthases of angiosperms and highly expressed in petals of tight buds of scented cultivars. On the other hand, two GPPS genes, RhGPPS-LSU1 and RhGPPS1, were cloned. The expression revel of RhGPPS-LSU1 in petals of all scented cultivars and one non-scented cultivar was high.
