Flavonoid biomarkers and co-expression gene networks characterized in ten Hemerocallis citrina accessions via multi-omics.

ABSTRACT: Hemerocallis citrina Baroni (H. citrina), a traditional medicinal and edible plant, is rich in bioactive flavonoids. This study investigated flavonoid metabolites in H. citrina flowers from ten accessions using UPLC-MS/MS-based metabolomics. A total of 642 flavonoids and 14 tannins were identified in the flowers. Among these, 375 flavonoids were classified as flavonols and flavone, representing for 39.33% and 17.53%, respectively. The identification of 309 differential flavonoid metabolites was achieved through analyses of nine pairwise comparison groups. These differential flavonoids in flowers of H. citrina could be distinctly categorized into two groups, clearly separating the 7 edible accessions from the 3 non-edible accessions. Significant variations in 14 flavonoid markers were obser
