Flavonol 3‐O‐diglucosides with a 1→2 inter‐glycosidic linkage are representative pollen‐specific flavonols that are widely distributed in plants, but their biosynthetic genes and physiological roles are not well understood. Flavonoid analysis of four Arabidopsis floral organs (pistils, stamens, peta...
