1.1.1.207 agriculture transcript level of menthol dehydrogenase/menthone reductase is highly upregulated in plants treated with calliterpenone, leading to increased content of menthone and menthol in oil 726206 1.1.1.207 agriculture water stress decreases the gene expression levels of pulegone reductase and menthol dehydrogenase, but increases the expression of trans-isopiperitenol dehydrogenase, isopiperitenone reductase and menthofuran synthase. The most of essential oil components (menthol, menthofuran, and plugene) are positively correlated with genes expression. Drought stress induces increasing contents of pulegone and menthofuran and reduces menthol percentages 760311 1.1.1.207 synthesis the enzyme is useful, together with menthone:(+)-neomenthol reductase (EC 1.1.1.208), for production of (1R,2S,5R)-(-)-menthol and (1S,2S,5R)-(+)-neomenthol from pulegone, development of a one-pot synthesis method, overview. Menthol isomers, (1R,2S,5R)-(-)-menthol, (1R,2S,5S)-(+)-isomenthol, (1S,2S,5R)-(+)-neomenthol, and (1R,2R,5R)-(+)-neoisomenthol, and carvone are used as additives in oral hygiene products and flavors in food and beverages, or cosmetics 739778
