The present study investigated the accumulation of stilbene compounds (trans- and cis-resveratrol, piceides, and piceatannol) and induction of gene expression related to their synthesis in the berries of ‘Campbell Early’ and ‘Kyoho’ grapes following treatment with water-based shoot extracts from hairy vetch and ryegrass. Trans-resveratrol was present in substantial amounts (4.1 ± 0.0 to 5.3 ± 0.07 μg/g fresh weight) in ‘Campbell Early’ and (7.6 ± 1.24 to 10.4 ± 0.35 07 μg/g fresh weight) in… Expand

System-Level and Granger Network Analysis of Integrated Proteomic and Metabolomic Dynamics Identifies Key Points of Grape Berry Development at the Interface of Primary and Secondary Metabolism
A comparison of the anthocyanin profile of Early Campbell to other cultivars revealed similarities to Concord grape and indicates the strong effect of genetic background on metabolic partitioning in primary and secondary metabolism. Expand

Recent technological developments and public awareness regarding health and diseases have brought a tremendous shift in dietary patterns. Presently, due to increased burden of diseases people areExpand


Ripening and genotype control stilbene accumulation in healthy grapes.
High resveratrol levels are also accompanied by the up-regulation of genes involved in plant defense and the concomitant underexpression of genes related to the ripening process and to indole alkaloid synthesis. Expand
Induction of stilbenes in grapes by UV-C: Comparison of different subspecies of Vitis
Bioactive products enriched in stilbenes are considered of potential future interest, and the main sources of stilbenes in human diet are grapes. Postharvest ultraviolet C (UV-C) treatment was usedExpand
Elicitation and accumulation of stilbene phytoalexins in grapevine berries infected by Botrytis cinerea
It can be assumed that after extraction and degradation e-viniferin of mature berries is a source of resveratrol in wine. Expand
Resveratrol and Stilbene Synthase mRNA Production in Grapevine Leaves Treated with Biotic and Abiotic Phytoalexin Elicitors
Three elicitors of grapevine defense mechanisms—UV irradiation, aluminum chloride, and Botrytis cinerea —did not induce the same StSy mRNA production in V. rupestris, but similar profiles were observed for resveratrol accumulation, showing that stilbene synthesis is correlated to St Sy mRNA production.

Influence of fosetyl-Al on phytoalexin accumulation in the Plasmopara viticola-grapevine interaction
It is suggested that a combination of direct (= primary) and indirect (= secondary) modes of action exert a double selection pressure on the fungus which may explain the rarity of fosetyl-Al-resistant strains in the field. Expand
Resveratrol accumulation and resveratrol synthase gene expression in response to abiotic stresses and hormones in peanut plants
The results suggest that resveratrol synthesis is induced by biotic and abiotic factors through the regulation of RS transcription, and that stress hormones such as SA and ethylene are involved in the RS gene expression in peanut. Expand
Localization of stilbene synthase in Vitis vinifera L. during berry development
The location of STS in exocarp cell wall is consistent with its role in synthesizing defense compounds and supports the hypothesis that a differential localization of phenylpropanoid biosynthetic machinery regulates the deposition of specific secondary products at different action sites within cells.

In vivo antibacterial activity against 'Rhizobium vitis' and the induction of defense-related genes in grapevines ('Vitis' spp.) by hairy vetch and ryegrass extracts
Results suggest that extracts from tested cover crops can act as efficient biological inducers and therefore serve as an alternative strategy for grapevine crown gall protection. Expand
Biological Activity of Resveratrol, a Stilbenic Compound from Grapevines, Against Botrytis cinerea, the Causal Agent for Gray Mold
The biological activity of resveratrol, a stilbenic compound synthesized by grapevines in response to various stresses, was reevaluated against Botrytis cinerea using a novel in vitro system that enabled direct observation of the fungus with an inverted microscope to reinforce the role played by this compound in the B. cine Andrea–grapevine interaction.

Ethephon elicits protection against Erysiphe necator in grapevine.
Ethephon treatment triggered the protection of grapevine detached leaves and grapevine foliar cuttings against Erysiphe necator, the causal agent of powdery mildew, and these studies emphasize the major role of ethylene in grapevine defense. Expand
