Among the many secondary plant metabolites, resveratrol attracts the attention of researchers because of its unique biological and pharmacological properties. Amur grape (Vitis amurensis Rupr.), including resveratrol-producing plant, has a high level of content of phenolic compounds. Despite a number of activities aimed at the study of the regulation of the biosynthesis of resveratrol, an understanding of the mechanism of transcriptional regulation of genes of key enzymes of this metabolic pathway—the STS gene—it has a lot of white spots. This study aims to examine the role in the biosynthesis of resveratrol transcription factor VaMyb1 belonging to a large group R2R3-Myb transcription factors plant. During the study of the transcription factor gene expression in the cells of V. amurensis and the impact of its increased expression in the content of resveratrol and the expression of STS genes, evidence of its negative role in the biosynthesis of resveratrol was obtained.
