Stilbene Production by Vitis vinifera Cell Suspension Cultures: Methyl Jasmonate Induction and 13C Biolabeling
Vitis vinifera cells grown in vitro respond to methyl jasmonate (MeJa) with enhancement of phytoalexin accumulation. MeJa added during the first half of the exponential growth phase increased the… Expand
Distribution of [14C]-trans-resveratrol, a cancer chemopreventive polyphenol, in mouse tissues after oral administration.
Trans-resveratrol, a phenolic compound present in wine, has been reported to be a potential cancer chemopreventive agent. However, although it has numerous biological activities in vitro, there are… Expand
Wild-mushroom intoxication as a cause of rhabdomyolysis.

Abstract Sucrose was found to modulate polyphenol accumulation in Vitis vinifera cell cultures. The production of anthocyanins increased 12-fold after addition of 0.15 m sucrose, while that of… Expand
Direct liquid chromatographic analysis of resveratrol derivatives and flavanonols in wines with absorbance and fluorescence detection
Abstract Wine contains a large number of polyphenols including stilbenes, flavanols and anthocyanins. Of these, stilbenes have been reported to have potential chemopreventive activities. We describe… Expand
Airborne Methyl Jasmonate Induces Stilbene Accumulation in Leaves and Berries of Grapevine Plants
The study investigated whether gaseous methyl jasmonate (MeJa) can induce stilbene accumulation and synthesis potential in response to an abiotic stress (ultraviolet light) in grapevine leaves and… Expand
Sugar sensing and Ca2+-calmodulin requirement in Vitis vinifera cells producing anthocyanins.

We have previously reported that sucrose modulates anthocyanin biosynthesis in cell suspension cultures of Vitis vinifera L. The main role of sugar in this response does not seem to be that of… Expand
The Accumulation of Stilbene Glycosides in Vitis vinifera Cell Suspension Cultures
- P. W. Teguo, A. Décendit, S. Krisa, G. Deffieux, J. Vercauteren, J. Mérillon
- 23 December 1996
Suspension cultures of Vitis vinifera grown in an inducive polyphenol synthesis medium accumulated stilbene glycosides. (E)-piceatannol (3,5,3‘,4‘-tetrahydroxystilbene) 3-O-β-glucoside (2) and… Expand
Fungal enzymic activity degrading 1,4-α-D-glucans to 1,5-D-anhydrofructose
Abstract 1,5- d -Anhydrofructose, the precursor of the antibiotic pyrone microthecin in morels and other fungi, is produced in Morchella vulgaris by a novel enzymic activity, presumably a lyasic one,… Expand
