| | Main components of the powerful minty, fresh-green, herbal scented essential oil of Mentha x piperita L. from USA (Kennewick type, notsubsp. piperita from Kennewick) were menthol (40.7%), menthone (23.4%), 1,8-cineole (5.3%), menthyl actetate (4.2%), isomenthone (3.7%), menthofurane (3.7%), neomenthol (3.2%), limonene (2.6%), pulegone (1.9%), β-caryophyllene (1.7%), and β-pinene (1.1%). \\ |

| "Peppermint (Mentha × piperita L.) was transformed with various gene constructs to evaluate the utility of metabolic engineering for improving essential oil yield and composition... The most promising results were obtained by transforming plants expressing an antisense version of (+)-menthofuran synthase, which is critical for adjusting the levels of specific undesirable oil constituents, with a construct for the overexpression of the MEP pathway gene 1-deoxy-D-xylulose 5-phosphate reductoisomerase (up to 61% oil yield increase over wild-type controls with low levels of the undesirable side-product (+)-menthofuran and its intermediate (+)-pulegone). Elite transgenic lines were advanced to multiyear field trials, which demonstrated consistent oil yield increases of up to 78% over wild-type controls and desirable effects on oil composition under commercial growth conditions. The transgenic expression of a gene encoding (+)-limonene synthase was used to accumulate elevated levels of (+)-limonene, which allows oil derived from transgenic plants to be recognized during the processing of commercial formulations containing peppermint oil. Our study illustrates the utility of metabolic engineering for the sustainable agricultural production of high quality essential oils at a competitive cost." \\ | "Peppermint (Mentha × piperita L.) was transformed with various gene constructs to evaluate the utility of metabolic engineering for improving essential oil yield and composition...
