Ethanol metabolism is known to induce overwhelming production of reactive oxygen species (ROS) and also to cause associated immune dysfunction. Several interventional agents of plant origin, in particular fruits and vegetables have been used to counteract these alterations induced by ethanol. In this study, we investigated the efficacy of dietary feeding of skin and flesh of grapes (Vitis vinif...

Grape thaumatin-like proteins (TLPs) play roles in plant-pathogen interactions and can cause protein haze in white wine unless removed prior to bottling. Different isoforms of TLPs have different hazing potential and aggregation behavior. Here we present the elucidation of the molecular structures of three grape TLPs that display different hazing potential. The three TLPs have very similar stru...

Somatic mutation is a natural mechanism which allows plant growers to develop new cultivars. As a source of variation within a uniform genetic background, it also represents an ideal tool for studying the genetic make-up of important traits and for establishing gene functions. Layer-specific molecular characterization of the Pinot family of grape cultivars was conducted to provide an evolutiona...

Plant-derived polyphenols have been shown to influence bone turnover and bone properties in the estrogen-depleted state. We used a crossover design in ovariectomized rats (n = 16 rats for each diet) to investigate the effect of supplementation of two doses each of blueberry, plum, grape, grape seed extract, and resveratrol on bone. We tested the aglycon and glucoside forms of genistein to quant...

Epidemiological studies of Pierce’s disease (PD) can be confounded by a lack of genetic information on the bacterial causative agent, Xylella fastidiosa (Xf). PD in grape is caused by genetically distinct strains of Xf subsp. fastidiosa (Xff), but is not caused by numerous other strains or subspecies of Xf that typically colonize plants other than grape. Detection assays such as ELISA and qPCR ...

abstract this survey tries to use of competitive advantage analysis of agricultural productions with shift share method. to arrive this target used of official published statistics in ten years priod (1374-1384) were used. the results explained north khorasan has competitive advantage in onion, melon, tomato and grape production. also in this survey, appointment potentials of low plant surface ...

Grape ripe rot (Colletotrichum viniferum) causes huge losses in grape production vineyards southern China. However, the molecular mechanism against species and responsive genes implicated these processes are relatively unknown. Here, we present transcriptome analysis of berries from a C. viniferum-resistant (Vitis davidii Föex). Uninfected at day zero were used as control samples (CK), an inocu...

The aim of this study was to evaluate the effect of some natural extracts obtained from grape pomace (GPE) and grape seeds (GSE) as compared to a synthetic food, antioxidant-butylated hydroxytoluene (BHT), in order to control fungal population and ochratoxin A (OTA) production in naturally contaminated wheat. The results showed that the addition of these extracts was efficient with OTA content ...

The effects of grape seeds extract and grape peels extract prepared from grape pomace on the activity of antioxidant enzymes, degree of lipid peroxidation in serum and liver tissue were investigated in rabbits fed on high cholesterol diet. New Zealand white rabbits were divided as follows ; 1) NOR (normal group); 2) CHOL (cholesterol group); 3) GSH (cholesterol + grape seed extract group); 4) G...

This project focuses on the lipopolysaccharide (LPS) component of the outer membrane of Xylella fastidiosa (Xf). In particular, we are investigating if the O-antigen portion of this molecule contributes to Xf surface attachment and biofilm formation. More importantly, by targeting genes involved in O-antigen biosynthesis, we will determine if LPS is an important virulence factor for Xf infectio...
