[Effect of plant stilbene precursors on the biosynthesis of resveratrol in Vitis amurensis Rupr. cell cultures].

The biosynthesis of resveratrol after the application of a precursor for biosynthesis, i.e., phenylalanine (Phe), has been studied. The application of Phe has been shown to increase significantly the expression of the phenylalanine-ammonia-lyase (PAL) and stilbene synthase (STS) genes and enhance the production of resveratrol by 8.5 times. Data on resveratrol production after the addition of Phe and coumaric acid (CA) were compared with known analogs.
