AKR genes in Asteraceae
Some Asteraceae species accumulate yellow flavonoids such as 6'-deoxychalcones. For the biosynthesis of 6'-deoxychalcones, an aldo-keto reductase (AKR) is required in addition to chalcone synthase (CHS), a general flavonoid biosynthetic enzyme. This study aims to analyze the AKR genes involved in 6'-deoxychalcone biosynthesis in these Asteraceae species.
