geranium tuberosum/nicotine

A geranium (Pelargonium graveolens) chloroplast translational elongation factor EF-Tu (tufA) cDNA was isolated. The geranium tufA cDNA is 1,584 bp long with 20 bp of 5' untranslated region (UTR) and 139 bp of 3' UTR. It encodes 474 amino acids including a putative chloroplast transit peptide of 65

The overexpression of dihydroxyacetone synthase (DAS) and dihydroxyacetone kinase (DAK) from methylotrophic yeasts in chloroplasts created a photosynthetic formaldehyde (HCHO)-assimilation pathway (DAS/DAK pathway) in transgenic tobacco. Geranium has abilities to absorb and metabolize HCHO. Results

Wild plant species were systematically sampled to characterize reproduction of thrips, the vector of Tomato spotted wilt virus (TSWV), and natural sources TSWV infection. Thrips populations were monitored on 28 common perennial, biennial, and annual plant species over two noncrop seasons at six

Several strains of tobacco ringspot virus (TobRV) support the replication and encapsidation of satellite tobacco ringspot virus RNA (STobRV RNA). We have compared the nucleotide sequences of four STobRV RNAs, each initially associated with a different isolate of TobRV. A STobRV RNA from a geranium

The multistage induction theory is generally regarded as the mechanism of carcinogenesis. In order to prevent the initiation stage of carcinogenesis, it is meaningful to discover the functional components of edible plants. The objective of this research was to test the antimutagenicity of the

Ralstonia solanacearum race 3 biovar 2 strains are considered select agents by the U.S. government because they are not endemic to the United States and have the potential to cause brown rot in our potato production fields. Simple and accurate methods are needed for quick identification prior to

When cotton, geranium, petunia, tobacco, tomato, and velvetleaf were presented simultaneously to strains of the Heliothine moth, Heliothis virescens (F.), from Arizona (AZ), Mississippi (MS), and North Carolina (NC), oviposition choices were similar, while a strain from the Virgin Islands (VI) was

OBJECTIVE To evaluate the antimicrobial effects of essential oils (EOs) from cassia, basil, geranium, lemongrass, cumin and thyme, as well as their major components, against Phytophthora parasitica var. nicotianae; to investigate morphological changes in hyphae and sporangia in response to treatment

The objective of this research was to examine the radical scavenging activity of traditional Japanese herbs. Samples used in the experiments were gennoshoko (Geranium nepalense var. thunbergii), yomogi (Artemisia vulgaris var.indica), senburi (Swertia japonica), iwa-tobacco (Conandron ramondioides),

In 2003 and 2004, 15 isolates of Ralstonia solanacearum were obtained from wilting plants of field-grown pepper (Capsicum annuum) in south Florida and from pot-grown hydrangea (Hydrangea paniculata and H. macrophylla) and geranium (Pelargonium × hortorum) in commercial nurseries and retention ponds

Each year, large volumes of ornamental and food plant propagative stock are imported into the North America; occasionally, Ralstonia solanacearum is found systemically infecting this plant material. In this study, 107 new R. solanacearum strains were collected over a 10-year period from imported
