While mechanism underlying stress response C. remains unknown. In this study, we investigated transcriptomics and flavonoid metabolomics responses leaves under different conditions. We identified a total 2401 differentially expressed genes (DEGs) drought-treated leaves. The continuously increasing DEGs were significantly enriched pathways related to phenylpropanoid biosynthesis, galactose metabolism. flavonoids content also found increased during treatment . A 57 distinct using UPLC-MS/MS. Among them, nine out ten accumulated metabolites (DAMs) displayed notable accumulation profiles These DAMs included two flavanols [(-)-Catechin gallate (-)-gallocatechin gallate], flavonols (myricetin astragalin), four flavones (orientin, cynaroside, isoorientin, vitexin), one flavanone (naringenin-7-glucoside), indicating their pivotal roles response.
