Grapevine fleck virus-like viruses in Vitis.

Numai utilizatorii înregistrați pot traduce articole

Two sets of degenerate primers for the specific amplification of 572-575 nt and 386 nt segments of the methyltransferase and RNA- dependent RNA polymerase cistrons of members of the genera Tymovirus and Marafivirus and of the unassigned virus Grapevine fleck virus (GFkV) were designed on the basis

First Report of Grapevine leafroll-associated virus 2 Infecting Muscadine (Vitis rotundifolia) and Summer Grape (Vitis aestivalis) in the United States.

Numai utilizatorii înregistrați pot traduce articole

A study, designed to gain some knowledge of viruses infecting native grapes in the southeastern United States, presently limited to a single paper (4), was initiated in spring of 2012. In the first phase of this investigation, 28 samples of muscadine (Vitis rotundifolia) and summer (V. aestivalis)

Evidence of a sirtuin gene family in grapevine (Vitis vinifera L.).

Numai utilizatorii înregistrați pot traduce articole

Sirtuins are known as regulators of age-dependent gene transcription and chromatin modification in yeast and in animals, but information about their occurrence and role in plants is scarce. Sirtuin-like sequences were amplified using two highly degenerate primers designed comparing sirtuin sequences

PCR cloning of partial nbs sequences from grape (Vitis aestivalis Michx).

Numai utilizatorii înregistrați pot traduce articole

Plants defend themselves against pathogens via the expressions of disease resistance (R) genes. Many plant R gene products contain the characteristic nucleotide-binding site (NBS) and leucine-rich repeat (LRR) domains. There are highly conserved motifs within the NBS domain which could be targeted

Targetting and optomotor space in the leaf-hopper Empoasca vitis (Gothe) (Hemiptera: Cicadellidae)

Numai utilizatorii înregistrați pot traduce articole

The accuracy with which the visuomotor system of Empoasca vitis can prescribe a jump trajectory towards a bright, uniformly illuminated target shape was investigated. The targets consisted of discs, rings or bars cut out of black card and mounted in front of a source of stroboscopic light diffused

Resistance gene analogs are candidate markers for disease-resistance genes in grape ( Vitis spp.).

Numai utilizatorii înregistrați pot traduce articole

A set of NBS-containing sequences was isolated from genomic DNA of two grape species ( Vitis amurensis and Vitis riparia) and characterised in a panel of Vitis genotypes carrying different levels of resistance against downy mildew and other diseases. A PCR-mediated approach made use of degenerate

Anti-inflammatory effects of Vitis thunbergii var. taiwaniana on knee damage associated with arthritis.

Numai utilizatorii înregistrați pot traduce articole

Vitis thunbergii Sieb. et Zucc. var. taiwaniana Lu (VT) is an indigenous plant in Taiwan that is traditionally used for promoting joint health. In this study, we used in vitro primary human chondrocytes (PHCs) and two in vivo animal models to evaluate the anti-inflammatory effects of VT on

Chemical and spectroscopic characteristics of the wood of Vitis vinifera cv. Sangiovese affected by esca disease.

Numai utilizatorii înregistrați pot traduce articole

Chemical and spectroscopic analyses ((13)C cross-polarization-magic angle spinning NMR and attenuated total reflection Fourier transform infrared spectroscopies) were carried out on the wood of Vitis vinifera cv. Sangiovese with brown-red discoloration and black streaks caused by esca disease. The

Structural modifications induced by Eutypa lata in the xylem of trunk and canes of Vitis vinifera

Numai utilizatorii înregistrați pot traduce articole

Eutypa dieback, a devastating disease in grapevines, is caused by the fungal pathogen Eutypa lata, a wood-inhabiting fungus. E. lata acts by degrading wood tissues in the colonisation areas, and produces foliar symptoms. These striking symptoms have been attributed to the production of toxic

Expression of calcium-dependent protein kinase (CDPK) genes under abiotic stress conditions in wild-growing grapevine Vitis amurensis.

Numai utilizatorii înregistrați pot traduce articole

Calcium-dependent protein kinases (CDPKs), which are important sensors of Ca(2+) flux in plants, are known to play essential roles in plant development and adaptation to abiotic stresses. In the present work, we studied expression of CDPK genes under osmotic and temperature stress treatments in

Grapevine fanleaf virus affects grape (Vitis vinifera) berry anthocyanin content via the transcriptional regulation of anthocyanin biosynthetic genes.

Numai utilizatorii înregistrați pot traduce articole

Grapevine fanleaf virus (GFLV) causes grapevine fanleaf degeneration, one of the oldest known viral diseases of grapevines. The virus has been found in all winegrowing regions around the world. In the seasons 2011-12 a comparison between field grown GFLV-infected and healthy grapevines was conducted

Rs-198 Liquid Biofertilizers Affect Microbial Community Diversity and Enzyme Activities and Promote Vitis vinifera L. Growth

Numai utilizatorii înregistrați pot traduce articole

Chemical fertilizers were applied on perennial tree vines to obtain high yields, which have resulted in considerable deterioration of soil quality, and it is likely to have negative impacts on the development of the grape industry. In this study, P. putida Rs-198 liquid biofertilizer

Polypeptide metabolites secreted by the fungal pathogen Eutypa lata participate in Vitis vinifera cell structure damage observed in Eutypa dieback

Numai utilizatorii înregistrați pot traduce articole

Eutypa dieback is a devastating disease of Vitis vinifera L. caused by the fungal pathogen Eutypa lata. This wood-inhabiting fungus degrades tissues in the trunk and cordons of infected vines and induces symptoms in the foliage. These symptoms have been attributed to the production of toxic

Hepatoprotective effect of the ethanol extract of Vitis thunbergii on carbon tetrachloride-induced acute hepatotoxicity in rats through anti-oxidative activities.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Vitis thunbergii var. taiwaniana are traditionally used for the treatment of diarrhea, fracture and injury, jaundice, and hepatitis in Taiwan. OBJECTIVE The hepatoprotective activity of its plant extracts seems to be been associated with its antioxidant activity. This paper aims to

A Special Ingredient (VtR) Containing Oligostilbenes Isolated from Vitis thunbergii Prevents Bone Loss in Ovariectomized Mice: In Vitro and In Vivo Study.

Numai utilizatorii înregistrați pot traduce articole

Vitis thunbergii is used in Taiwan as a botanical supplement for inflammatory bone diseases. This study aims to examine its direct effect on bone metabolism. Three-month-old female mice were randomly divided into ovariectomized control (OVX), sham operated (SHAM), and ovariectomy treated with either
