vitis/atrophy

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

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)

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

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

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

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

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 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

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

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 (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

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

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

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

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
