Peanut is rich in resveratrol, which has a very high nutritional value and health care function. Stilbene synthase (STS) is the key enzyme in resveratrol synthesis. In this research, we identified 50 peanut STS and 17 chalcone synthase (CHS) gene members from peanut genome by using multiple bioinformatics methods. Further, the chromosome location, phylogeny, exon-intron structure, and expression pattern of the gene family members was conducted, the results showed that most of the STS genes high expressed in root, testa, pericarp and gynophore, all the expressed 45 STS and 8 CHS genes response to UV treatment. This study laid a foundation for the functional identification of peanut STS/CHS genes, and provided theoretical basis and genetic resources for high-quality peanut breeding.

Key words: peanut, resveratrol, STS/CHS gene family, evolutionary analysis, expression aanalysis
