Potential Associations among Bioactive Molecules, Antioxidant Activity and Resveratrol Production in Vitis vinifera Fruits of North America

Molecules, 2022
Grapes (Vitis vinifera L.) are rich in bioactive molecules contributing to health benefits. Consumption of grapes is linked to reduced incidence of cardiovascular diseases.

Novel polyketides synthesized with a higher plant stilbene synthase [PDF]

European Journal of Biochemistry, 2001
The physiological function of the stilbene synthase (STS) from groundnut (Arachis hypogaea) is the formation of resveratrol. The enzyme uses 4‐coumaroyl‐CoA, performs three condensations with malonyl‐CoA, and folds the resulting tetraketide into a new aromatic ring system.

Production of highly bioactive resveratrol analogues pterostilbene and piceatannol in metabolically engineered grapevine cell cultures [PDF]

, 2017
Summary Grapevine stilbenes, particularly trans-resveratrol, have a demonstrated pharmacological activity. Other natural stilbenes derived from resveratrol such as pterostilbene or piceatannol, display higher oral bioavailability and bioactivity than the

Crystal structure of stilbene synthase from Arachis hypogaea [PDF]

Proteins: Structure, Function, and Bioinformatics, 2005
Introduction. Stilbene synthase [STS; Enzyme Commission (EC) 2.3.1.95] and chalcone synthase (CHS; EC 2.3.1.74) are members of the type III polyketide synthases (PKSs) and plant-specific enzymes. 1 CHS is widely found in higher plants and plays a key role in the flavonoid biosynthesis by supplying chalcone to downstream enzymes.

Cross‐reaction of chalcone synthase and stilbene synthase overexpressed in Escherichia coli [PDF]

FEBS Letters, 1999
Chalcone synthase (CHS) and stilbene synthase (STS) are related plant polyketide synthases belonging to the CHS superfamily. CHS and STS catalyze common condensation reactions of p‐coumaroyl‐CoA and three C2‐units from malonyl‐CoA but different cyclization reactions to produce naringenin chalcone and resveratrol, respectively.

Tolerance of Arabidopsis thaliana plants overexpressing grapevine VaSTS1 or VaSTS7 genes to cold, heat, drought, salinity, and ultraviolet irradiation

Biologia Plantarum, 2021
Stilbene synthases (STS) are plant enzymes that are responsible for the biosynthesis of stilbenes, which are plant phenolic compounds with valuable biological properties.

The influence of downy mildew tolerance of grape varieties on the biosynthesis of stilbenes in callus as potential sources of bioactive substances*

BIO Web of Conferences, 2020
Stilbenes represent a considerable practical interest in relation to their benifits to the human health. Callus culture of the grape, which is a natural producer of stilbenes, can serve as an effective source of these compounds.

The Influence of the Grapevine Bacterial and Fungal Endophytes on Biomass Accumulation and Stilbene Production by the In Vitro Cultivated Cells of Vitis amurensis Rupr.

Plants, 2021
Plant endophytes are known to alter the profile of secondary metabolites in plant hosts. In this study, we identified the main bacterial and fungal representatives of the wild grape Vitis amurensis Rupr. microbiome and investigated a cocultivation effect

Down-Regulation of Phosphoenolpyruvate Carboxylase Kinase in Grapevine Cell Cultures and Leaves Is Linked to Enhanced Resveratrol Biosynthesis

Biomolecules, 2021
In grapevine, trans-Resveratrol (tR) is produced as a defence mechanism against stress or infection. tR is also considered to be important for human health, which increases its interest to the scientific community.

Overexpression of a stilbene synthase gene from Fallopia multiflora causes trans-piceid accumulation in transgenic Arabidopsis

Biologia Plantarum, 2020
Fallopia multiflora, also known as Polygonum multiflorum, is a traditional Chinese medicine with stilbenes as the main characteristic components. We previously isolated the presumed stilbene synthase gene FmSTS1 from F. multiflora and inserted the FmSTS1
