Grapevine leafroll disease (GLD) is an economically important virus disease affecting wine grapes (Vitis vinifera L.), but little is known about its effect on wine chemistry and sensory composition of wines. In this study, impacts of GLD on fruit yield, berry quality and wine chemistry and sensory features were investigated in a red wine grape cultivar planted in a commercial vineyard. Own-root...

Grape (Vitis vinifera) produces a variety of secondary metabolites, which can enhance nutrients and flavor in fruit wine. Uridine diphosphate-glycosyltransferases (UGTs) are primarily responsible for the availability metabolites by glycosylation modification. Here, total 228 putative UGTs were identified V. vinifera, VvUGTs clustered into 15 groups (A to O) unevenly distributed on 18 chromosome...

different grapevine cultures that were inoculated with Plasmopara viticola as a host pathogen and Pseudoperonospora cubensis as a non-host pathogen. The results of the expression analysis showed that the PR1 mRNA level in Vitis vinifera cv. Riesling and Vitis riparia cv. Gloire de Montpellier is mainly affected by the culture system. PR1 is constitutively expressed in callus cultures. In vitro ...

Glucose, fructose, galactose, sucrose, maltose, melibiose, raffinose, and stachyose were identified in the leaves, bark, roots, and berries of Vitis vinifera L. var. Thompson Seedless. In addition to these sugars, verbascose and manninotriose were found in the leaves and bark.Malic, tartaric, citric, isocitric, ascorbic, cis-aconitic, oxalic, glycolic, glyoxylic, succinic, lactic, glutaric, fum...
