Abstract The production of anthocyanin is regulated by light and corresponding photoreceptors. In this study, we found that exposure to blue overexpression CRY1a are associated with increased accumulation in tomato ( Solanum lycopersicum L.). These responses the result changes mRNA protein levels SlHY5 , which a transcription factor. vitro vivo experiments using electrophoretic mobility shift assay ChIP‐qPCR assays revealed could directly recognize bind G‐box ACGT‐containing element promoters biosynthesis genes, such as chalcone synthase 1, 2, dihydroflavonol 4‐reductase . Silencing OE‐ lines decreased anthocyanin. findings presented here not only deepened our understanding how controls photoprotection leaves, but also allowed us explore potential targets for improving pigment production.
