Wild-type tobacco (Nicotiana tabacum) plants emit low levels of terpenoids, particularly from the flowers. By genetic modification of tobacco cv Petit Havana SR1 using three different monoterpene synthases from lemon (Citrus limon L. Burm. f.) and the subsequent combination of these three into one

Eureka lemon (Citrus limon) is an economically important crop in China. In 2009, a new disease was observed on Eureka lemon in an orchard of Ruili city in Yunnan Province. Nearly 10% of the plants were symptomatic with yellow vein clearing on lateral veins, combined with leaf crinkling and warping

Melissa officinalis (lemon balm) is a traditional herbal medicine, which enjoys contemporary usage as a mild sedative, spasmolytic and antibacterial agent. It has been suggested, in light of in vitro cholinergic binding properties, that Melissa extracts may effectively ameliorate the cognitive

Melissa officinalis (Lemon balm) is a herbal medicine that has traditionally been attributed with memory-enhancing properties, but which is currently more widely used as a mild sedative and sleep aid. In a previous study it was demonstrated that a commercial Melissa extract led to dose-specific

Essential oils are increasingly of interest for use as novel drugs acting as antimicrobial and antiviral agents. In the present study, we report the in vitro antiviral activities of 29 essential oils, extracted from Chinese indigenous aromatic plants, against the tobacco mosaic virus (TMV). Of these

Monoterpenoid biosynthesis in tobacco was modified by introducing two subsequent enzymatic activities targeted to different cell compartments. A limonene-3-hydroxylase (lim3h) cDNA was isolated from Mentha spicata L. 'Crispa'. This cDNA was used to re-transform a transgenic Nicotiana tabacum'Petit

Monoterpenes are an important class of terpenoids that are commonly present in plant essential oils. These can be extracted from plants and are used in the flavouring and perfumery industry. Monoterpene synthases are the key enzymes in monoterpene biosynthesis, as they catalyse the cyclisation of

This study examined whether salivary nicotine concentrations would provide a useful index of plasma concentrations in studies of the effects of transdermal nicotine administration. Twenty-four subject smokers abstained from smoking for 12 h prior to admission to a clinical research unit ward and for

Mesophyll protoplasts of the kanamycin-resistant nightshade, Atropa belladonna, were fused with mesophyll protoplasts of the phosphinothricin resistant-tobacco, Nicotiana tabacum. A total of 447 colonies resistant to both inhibitors was selected. Most of them regenerated shoots with morphology

In the present paper, six categories of standard industrial grading tobacco provided by Hongta Group are taken as experimental samples, including three different tobacco locations-upper (B), middle(C) and lower(X) parts, with each part containing two kinds of tobacco colors-orange (O) and lemon

Soybean cyst nematode (SCN) (Heterodera glycines) commonly infests soybean (Glycine max), but has also been reported to infest haricot bean, mung bean, adzuki bean, some species of Lespedeza and Melilotus (3), purple deadnettle (Lamium purpureum), henbit (Lamium amplexicaule), field pennycress

Although some WRKYs have been characterized, regulatory roles of most WRKYs remain poorly understood. Herein, we elucidated function of FcWRKY40 from Fortunella crassifolia in salt tolerance via overexpression and virus-induced gene silencing (VIGS) and unraveled its target genes. Overexpression of

WRKY comprises a large family of transcription factors in plants, but most WRKY members are still poorly understood. In this study, we report functional characterization of a Group III WRKY gene (FcWRKY70) from Fortunella crassifolia. FcWRKY70 was greatly induced by drought and abscisic acid, but

The basic helix-loop-helix (bHLH) transcription factors are involved in a variety of physiological processes. However, plant bHLHs functioning in cold tolerance and the underlying mechanisms remain poorly understood. Here, we report the identification and functional characterization of PtrbHLH
