AbstractIt has previously been shown that exogenous application of p‐coumaric acid (CA), a precursor of phenolic compounds, improved stilbene production in cell cultures of Vitis amurensis. This study examines the effect of cinnamic (Cin) and caffeic (Caf) acids, which are also phenolic precursors, on stilbene biosynthesis in the cell cultures.

Expression of a chimeric stilbene synthase gene in transgenic wheat lines
Transgenic Research, 1999A chimeric stilbene synthase (sts)‐gene was transferred into wheat. Stilbene synthases play a role in the defence against fungal diseases in some plant species (e.g. groundnut or grapevine) by producing stilbene‐type phytoalexins like resveratrol. Resveratrol is also claimed to have positive effects to human health.

COMPARATIVE ANALYSIS OF STILBENE SYNTHASE GENES AMONG VITIS SPECIES
Acta Horticulturae, 2007Stilbene synthase (StSy), encoded by a multigene family of several members, is the key enzyme to form resveratrol, the major component of the grapevine phytoalexin response. Genes encoding stilbene synthases have previously been described for several plant species including grapevine. Pierce's disease (PD), anthracnose and downy mildew are the limiting

SummaryPhenolic compounds are essential components of the defensive chemical arsenal of conifer trees. This chemically diverse group encompasses stilbenoids, flavonoids, isoflavonoids, proanthocyanidins and lignans. All of them are produced from the common precursors, CoA esters of the phenylpropanoids: p‐coumaroyl‐CoA, cinnamoyl‐CoA, caffeoyl‐CoA and ...

Plant Cell Reports, 2008
The expression and functionality of a resveratrol synthase (RS) gene from peanut (Arachis hypogaea) was studied using an Agrobacterium tumefaciens-mediated transient expression system in Nicotiana benthamiana leaves. Functional analysis of RS was demonstrated by tracking its expression during 96 h.

A New Stilbene Synthase Gene from Muscadine (Vitis rotundifolia) Grape Berry
2007 Frontiers in the Convergence of Bioscience and Information Technologies, 2007Muscadine grapes contain high concentration of polyphenols that are known to be involved in plant defense. Resveratrol encoded by stilbene synthase (STS) is one of the important phenolic compounds found in muscadine grape that has antimicrobial activity as well as health benefit.

Characterization of a pine multigene family containing elicitor- responsive stilbene synthase genes
Plant Molecular Biology, 1999Young pine seedlings respond to environmental stress by induced synthesis of pinosylvin, a stilbene phytoalexin. Heartwood of pine trees is characterized by a high content of pinosylvin. The formation of pinosylvin from cinnamoyl-CoA and three molecules malonyl-CoA catalysed by pinosylvin synthase is typical of the genus Pinus.

4-hydroxy-2-pyrone formation by chalcone and stilbene synthase with nonphysiological substrates
Phytochemistry, 1998Valerophenone synthase (VPS) is a polyketide synthase that catalyzes the formation of the phloroglucinol derivatives in the synthesis of the bitter acids in hop (Humulus lupulus). The reaction uses isovaleryl-CoA or isobutyryl-CoA, but otherwise it is identical to that of the chalcone synthase in flavonoid biosynthesis.

Plant Cell Reports, 1981
Callus cultures were established from cotyledons of Arachis hypogaea. The cultured cells were shown to produce stilbene synthase (resveratrol-forming) if the cells were irradiated with 254 nm UV light. The lag period after which the stilbene synthase activity appeared was similar for cultured cells and intact cotyledons.
