Terpene biosynthesis in glandular trichomes of hop.
Hop (Humulus lupulus L. Cannabaceae) is an economically important crop for the brewing industry, where it is used to impart flavor and aroma to beer, and has also drawn attention in recent years due to its potential pharmaceutical applications. Essential oils (mono- and sesquiterpenes), bitter acids (prenylated polyketides), and prenylflavonoids are the primary phytochemical components that acc...
متن کاملBioenergetics of Monoterpenoid Essential Oil Biosynthesis in Nonphotosynthetic Glandular Trichomes.
The commercially important essential oils of peppermint (Mentha × piperita) and its relatives in the mint family (Lamiaceae) are accumulated in specialized anatomical structures called glandular trichomes (GTs). A genome-scale stoichiometric model of secretory phase metabolism in peppermint GTs was constructed based on current biochemical and physiological knowledge. Fluxes through the network ...
متن کاملBiochemical and Histochemical Localization of Monoterpene Biosynthesis in the Glandular Trichomes of Spearmint (Mentha spicata).
The primary monoterpene accumulated in the glandular trichomes of spearmint (Mentha spicata) is the ketone (-)-carvone which is formed by cyclization of the C(10) isoprenoid intermediate geranyl pyrophosphate to the olefin (-)-limonene, hydroxylation to (-)-trans-carveol and subsequent dehydrogenation. Selective extraction of the contents of the glandular trichomes indicated that essentially al...
متن کاملDevelopment of peltate glandular trichomes of peppermint.
Cryofixation and conventional chemical fixation methods were employed to examine the ultrastructure of developing peltate glandular trichomes of peppermint (Mentha x piperita). Our results are discussed in relation to monoterpene production and the mechanism of essential oil secretion. Peltate glands arise as epidermal protuberances (initials) that divide asymmetrically to produce a vacuolate b...
متن کاملDirect demonstration of duvatrienediol biosynthesis in glandular heads of tobacco trichomes.
Biosynthesis of the diterpenes, alpha and beta 4,8,13-duvatriene-1,3-diol, has been observed in detached, intact glandular heads from trichomes of Nicotiana tabacum, Tobacco Introduction 1068. This result shows directly that the glandular head portion of the trichome is capable of duvatrienediol biosynthesis. In additional experiments, all of the [(14)C] duvatrienediol formed from sodium [2-(14...
