Today in the wine industry, oenological tannins are widely used to improve wine quality and prevent oxidation in wine aging. With the development of tannin products, new oenological tannins are developed with many specific functions, such as modifying antioxidant effect, colour stabilization and aroma modifications. The aim of this work is to investigate effects of pre-fermentative addition of ...

Grape canes are a waste product from viticulture that show potential as an industrially extractable source of stilbenes, which are valuable for medical and other purposes. In this work, grape canes collected in three consecutive years (2014-2016) at six different places in South Moravia, Czech Republic were extracted, and the contents of trans-resveratrol, trans-ε-viniferin, and r2-viniferin we...

WRKY proteins comprise a large family of transcription factors that play important roles in plant defence regulatory networks, including responses to various biotic and abiotic stresses. To date, no large-scale study of WRKY genes has been undertaken in grape (Vitis vinifera L.). In this study, a total of 59 putative grape WRKY genes (VvWRKY) were identified and renamed on the basis of their re...

Abstract The quality of wine grapes depends on the balance between primary and secondary metabolites. Unlike many perennial crops that accumulate starch in fruits before ripening, non-climacteric ripe with no previous carbon reserves. Based assumption fruit sink is limiting metabolite accumulation grapes, bunch thinning performed to limit plant Sink/Source (S/S). We studied effects severe metab...

BACKGROUND The TIFY gene family constitutes a plant-specific group of genes with a broad range of functions. This family encodes four subfamilies of proteins, including ZML, TIFY, PPD and JASMONATE ZIM-Domain (JAZ) proteins. JAZ proteins are targets of the SCF(COI1) complex, and function as negative regulators in the JA signaling pathway. Recently, it has been reported in both Arabidopsis and r...

Sustained high levels of circulating catecholamines may induce cardiotoxicity through oxidative mechanisms. Isoproterenol is a synthetic catecholamine with increasing attention owing to this application in cardiology. The aim of the present study was to investigate the cardioprotective effects of Vitis vinifera seed against isoproterenolinduced myocardial ischemia. Normal Wistar strain rats wer...

Dietary stilbenoids are receiving increasing attention due to their potential health benefits. However, most studies concerning the bioactivity of stilbenoids were conducted with pure compounds, for example, resveratrol. The aim of this study was to characterize a complex root extract of Vitis vinifera in terms of its free radical scavenging and cellular antioxidant and anti-inflammatory proper...

This study aims to analyze the combination of grape leaf ethanol extract ( Vitis vinifera ) and cisplatin increase peroxisome proliferator-activated receptor gamma (PPARγ) expression inhibit HeLa cell proliferation in vitro. research described a new therapy method. included cytotoxicity test, test with 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) Assay, PPARγ using immunof...
