Abstract
In order to further explore the mechanism of 'sunshine muscat' grape russet formation, transcriptomic and metabolomic analyses were performed on 'sunshine muscat' grape peels with and without russet. A total of 1491 differentially expressed genes (DEGs) were discovered based on these analyses. The phenylpropane synthesis pathway was the key metabolic pathway identified, and 28 DEGs related to phenylpropane synthesis pathway were screened, of which 16 were related to lignin synthesis. In addition, 60 differential metabolites were screened. There were 29 phenolic substances among the differential metabolites, which were all up-regulated and 10 were quercetin-related glycosides. Our results indicate that phenols likely play a dominant role in the formation of 'sunshine muscat' grape russet, and the synthesis of lignin and quercetin may be the key factors underlying russet formation.
