Regulation of monoterpene accumulation in leaves of peppermint.
Plants synthesize numerous classes of natural products that accumulate during development and are thought to function as constitutive defenses against herbivores and pathogens. However, little information is available about how the levels of such defenses are regulated. We measured the accumulation of monoterpenes, a model group of constitutive defenses, in peppermint (Mentha x piperita L.) lea...
متن کاملDistribution of peltate glandular trichomes on developing leaves of peppermint.
The pattern of peltate glandular trichome initiation and ontogeny on expanding peppermint (Mentha x piperita) leaves was defined by surveying the populations of peltate glands in each of seven developmental stages within sampling areas of leaf apical, mid-, and basal zones for both abaxial and adaxial surfaces. It was shown that new peltate glands continue to form until leaf expansion ceases an...
متن کاملMonoterpene Metabolism. Cloning, Expression, and Characterization of (2)-Isopiperitenol/(2)-Carveol Dehydrogenase of Peppermint and Spearmint
The essential oils of peppermint (Mentha x piperita) and spearmint (Mentha spicata) are distinguished by the oxygenation position on the p-menthane ring of the constitutive monoterpenes that is conferred by two regiospecific cytochrome P450 limonene-3and limonene-6-hydroxylases. Following hydroxylation of limonene, an apparently similar dehydrogenase oxidizes (2)-trans-isopiperitenol to (2)-iso...
متن کاملMetabolism of Monoterpenes : Evidence for the Function of Monoterpene Catabolism in Peppermint (Mentha piperita) Rhizomes.
l-Menthone of peppermint leaves is reduced to d-neomenthol which is glucosylated and transported to the rhizome, whereupon the beta-d-glucoside is hydrolyzed, the aglycone oxidized back to l-menthone, and this ketone converted to l-3,4-menthone lactone. l-[G-(3)H]-3,4-Menthone lactone and its labeled progenitors, when incubated with excised mint rhizomes, gave rise to nonvolatile lipids as well...

چکیده پایان نامه (شامل خلاصه، اهداف، روش های اجرا و نتایج به دست آمده): کار جمع آوری گو یش های محلی در سال های اخیر شتاب امیدوار کننده ای به خود گرفته است. شاید از بارزترین اهداف جمع آوری گویش های مختلف، ثبت و ضبط آن، جلوگیری از نابودی و مهمتر از همه حل مشکلات دستوری زبان رسمی باشد. دقت در فرآیند های زبانی گویش های محلی نوع ارتباط مردم نواحی مختلف با پیرامون نشان را به ما نشان خواهد داد. از س...
