title: Geraniol synthases from perilla and their taxonomical significance.
abstract: Geraniol synthases were isolated from five pure strains of Perilla citriodora and Perilla frutescens which vary in essential oil type, the main compounds of which were citral, elsholtziaketone, perillaketone, and perillene, respectively. This result supports the putative biosynthetic pathways of these three furylalkenes which are all produced by way of citral. Nucleotide sequences of geraniol synthases from three oil types of P. citriodora were identical, and almost the same as the sequence from P. frutescens, a species with twice the chromosome number of P. citriodora. This identity in sequence between P. citriodora and P. frutescens, together with other previous results, indicates that P. frutescens was formed as an amphidiploid of P. citriodora and an unknown wild species.
