Sweet osmanthus is a traditional Chinese flower with abundant flavonoids in its petals. However, the regulatory mechanisms that produce these flavonoids remain unclear. Metabolomic analysis results revealed that 15 compounds in ‘Chenghong Dangui’ petals were upregulated compared to those in ‘Zaohuan...
