Geraniol synthases from perilla and their taxonomical significance

Geraniol synthases were isolated from citral, elsholtziaketone, perillaketone, and perillene types of Perilla spp. The synthases from Perilla citriodora and Perilla frutescens turned out to be almost identical in sequence, which indicates that P. frutescens was formed as an amphidiploid of P. citriodora and an unknown wild species.
