Assessing Potato Cultivar Sensitivity to Tuber Necrosis Caused by Tobacco rattle virus.

Numai utilizatorii înregistrați pot traduce articole

Tobacco rattle virus (TRV) causes the economically important corky ring spot disease in potato. Chemical control is difficult due to the soilborne nature of the TRV-transmitting nematode vector, and identifying natural host resistance against TRV is considered to be the optimal control measure. The

Tobacco arabinogalactan protein NtEPc can promote banana (Musa AAA) somatic embryogenesis.

Numai utilizatorii înregistrați pot traduce articole

Banana is an important tropical fruit worldwide. Parthenocarpy and female sterility made it impossible to improve banana varieties through common hybridization. Genetic transformation for banana improvement is imperative. But the low rate that banana embryogenic callus was induced made the

Promoter activity associated with the intergenic regions of banana bunchy top virus DNA-1 to -6 in transgenic tobacco and banana cells.

Numai utilizatorii înregistrați pot traduce articole

Promoter regions associated with each of the six ssDNA components of banana bunchy top virus (BBTV) have been characterized. DNA segments incorporating the intergenic regions of BBTV DNA-1 to -6 were isolated and fused to the uidA (beta-glucuronidase) reporter gene to assess promoter activity. In

MSI-99, a magainin analogue, imparts enhanced disease resistance in transgenic tobacco and banana.

Numai utilizatorii înregistrați pot traduce articole

Magainin is one of the earliest reported antimicrobial peptides isolated from skin secretions of the African clawed frog Xenopus laevis. A synthetic substitution analogue of magainin, MSI-99, is employed in this study to impart disease resistance in transgenic tobacco ( Nicotiana tabacumL.) and

Banana bunchy top virus (BBTV) nuclear shuttle protein interacts and re-distributes BBTV coat protein in Nicotiana benthamiana.

Numai utilizatorii înregistrați pot traduce articole

Banana bunchy top virus (BBTV) is a circular single-stranded DNA virus with multi-components. The knowledge about interaction between viral proteins and pathogenesis mechanism of BBTV remains unclear. In this study, the coat protein gene (CP, ORF 516 bp) and nuclear shuttle protein

Rolling Tobacco in Banana Leaves, Newspaper, or Copybook Paper Associated With Significant Reduction in Lung Function in Vanuatu.

Numai utilizatorii înregistrați pot traduce articole

In addition to the widespread availability of packaged cigarettes, the inhabitants of island nations of the Southwest Pacific frequently smoke commercially available loose tobacco using manufactured rolling papers, as well as locally grown tobacco rolled in manufactured rolling paper or wrapped in

Whole genome profiling physical map and ancestral annotation of tobacco Hicks Broadleaf.

Numai utilizatorii înregistrați pot traduce articole

Genomics-based breeding of economically important crops such as banana, coffee, cotton, potato, tobacco and wheat is often hampered by genome size, polyploidy and high repeat content. We adapted sequence-based whole-genome profiling (WGP™) technology to obtain insight into the polyploidy of the

First Report on Tobacco mild green mosaic virus in Calibrachoa Plants (Calibrachoa × hybrida) in Mississippi.

Numai utilizatorii înregistrați pot traduce articole

Six calibrachoa plants displaying reduced growth, general chlorosis, and blistering on the foliage were purchased from a retail store in Starkville, MS in 2007 and tested for possible virus infections. Transmission electron microscope observations of leaf-dip preparations revealed the presence of

Reinforcing effectiveness of nicotine in nonhuman primates: effects of nicotine dose and history of nicotine self-administration.

Numai utilizatorii înregistrați pot traduce articole

Despite the high prevalence of nicotine use in humans, robust nicotine self-administration has been difficult to demonstrate in laboratory animals. A parametric analysis of nicotine self-administration was conducted to study its reinforcing effects in nonhuman primates. Adult rhesus macaques (N = 6)

A promoter derived from taro bacilliform badnavirus drives strong expression in transgenic banana and tobacco plants.

Numai utilizatorii înregistrați pot traduce articole

Taro bacilliform virus (TaBV) is a pararetrovirus of the genus Badnavirus which infects the monocotyledonous plant, taro ( Colocasia esculenta). A region of the TaBV genome spanning nucleotides 6,281 to 12 (T1200), including the 3' end of open reading frame 3 (ORF 3) and the intergenic region to the

Anatabine significantly decreases nicotine self-administration.

Numai utilizatorii înregistrați pot traduce articole

Nicotine addiction is associated with many lethal disorders (cancer, cardiovascular and pulmonary disease), and more effective medications to aid smoking cessation are urgently needed. Anatabine is 1 of the most abundant minor tobacco alkaloids, but relatively little is known about its interactions

Degradation of the Plant Defense Signal Salicylic Acid Protects Ralstonia solanacearum from Toxicity and Enhances Virulence on Tobacco.

Numai utilizatorii înregistrați pot traduce articole

Plants use the signaling molecule salicylic acid (SA) to trigger defenses against diverse pathogens, including the bacterial wilt pathogen Ralstonia solanacearum SA can also inhibit microbial growth. Most sequenced strains of the heterogeneous R. solanacearum species complex can degrade SA via

Characterisation of pararetrovirus-like sequences in the genome of potato (Solanum tuberosum).

Numai utilizatorii înregistrați pot traduce articole

Three families of pararetrovirus-like sequences were isolated from the genome of potato using PCR of a characteristic fragment extending from the end of the transactivator domain. The potato pararetrovirus-like sequences are abundant in the nuclear genome of potato as demonstrated by their

Role for the banana AGAMOUS-like gene MaMADS7 in regulation of fruit ripening and quality.

Numai utilizatorii înregistrați pot traduce articole

MADS-box transcription factors play important roles in organ development. In plants, most studies on MADS-box genes have mainly focused on flower development and only a few concerned fruit development and ripening. A new MADS-box gene named MaMADS7 was isolated from banana fruit by rapid

Fruits and vegetables consumption and esophageal squamous cell carcinoma: a case-control study.

Numai utilizatorii înregistrați pot traduce articole

The authors examined the association of food group intakes and the risk of esophageal squamous cell carcinoma (SCC) in a hospital-based case-control study in Iran. In total, 47 patients with esophageal SCC and 96 controls underwent face-to-face private interviews. Usual dietary intake was assessed
