Substrate specificity in vivo and in vitro in the formation of stilbenes. Biosynthesis of rhaponticin.
Abstract The biosynthesis of the stilbene glucoside rhaponticin (3,5,3′-trihydroxy-4′-methoxystilbene 3-O-β- d -glucoside), a constituent of rhubarb (Rheum rhaponticum), was localized in the rhizome.Expand

Structural organization and differential expression of three stilbene synthase genes located on a 13 kb grapevine DNA fragment
A 13 kb DNA fragment was isolated from a grapevine (Vitis var. Optima) genomic library by hybridizing with elicitor-induced stilbene synthase cDNA as a probe. After fragmentation with Eco RI,Expand

Purification and properties of a stilbene synthase from induced cell suspension cultures of peanut.
Stilbene synthase ( resveratrol -forming) converts one molecule of rho- coumaroyl -CoA and three molecules of malonyl-CoA into 3,4',5- trihydroxystilbene . Following selective induction of stilbeneExpand

A phospholipase A2 is transiently synthesized during seed germination and localized to lipid bodies.
A patatin-like protein is present in the storage tissue of cucumber seedlings during the stage of fat mobilization. The cucumber protein is a homologue of a glycoprotein which in potatoes accountsExpand

Domains of the tetrafunctional protein acting in glyoxysomal fatty acid beta-oxidation. Demonstration of epimerase and isomerase activities on a peptide lacking hydratase activity.
Peroxisomes from different eukaryotic organisms house a multifunctional protein acting in fatty acid beta-oxidation. In plant glyoxysomes, one of the isoforms of this protein contains the activitiesExpand

Biosynthesis of fatty acid derived aldehydes is induced upon mechanical wounding and its products show fungicidal activities in cucumber.
Fatty acid 9/13-hydroperoxide lyase (9/13-HPL) in cucumber is an enzyme that can cleave either 9- or 13-hydroperoxides of polyunsaturated fatty acids to form C9- or C6-aldehydes, respectively, asExpand

The membrane-bound DnaJ protein located at the cytosolic site of glyoxysomes specifically binds the cytosolic isoform 1 of Hsp70 but not other Hsp70 species.
DnaJ proteins are located in various compartments of the eukaryotic cell. As previously shown, peroxisomes and glyoxysomes possess a membrane-anchored form of DnaJ protein located on the cytosolicExpand

Coordinate induction by UV light of stilbene synthase, phenylalanine ammonia-lyase and cinnamate 4-hydroxylase in leaves of vitaceae
A stilbene synthase catalyzing the formation of resveratrol from 4-hydroxycinnamoyl-CoA and malonyl-CoA was found in the leaves of several Vitaceae. This stilbene synthase and two other enzymesExpand

Coordinate- and elicitor-dependent expression of stilbene synthase and phenylalanine ammonia-lyase genes in Vitis cv. Optima.
The mechanisms controlling the induction of stilbene synthase and phenylalanine ammonia-lyase (PAL), two putative key regulatory enzymes of the biosynthetic pathway to stilbene phytoalexins, haveExpand

Characterization of a pine multigene family containing elicitor- responsive stilbene synthase genes
Young 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. TheExpand
