Identification of key genes regulating the synthesis of quercetin derivatives in Rosa roxburghii through integrated transcriptomics and metabolomics

Rosa roxburghii fruit is rich in flavonoids, but little is known about their biosynthetic pathways. In this study, we employed transcriptomics and metabolomics to study changes related to flavonoids at five different stages of R. roxburghii fruit development. Flavonoids and genes related to their biosynthesis were found to undergo significant changes in abundance across different developmental sta…
