[Metabolic pathway of flavonoids in Blumea balsamifera]

Abstract

To better understand the biosynthetic pathway of flavonoids in Blumea balsamifera, and to increase the biosynthesis of flavone and flavonol amount, we carried out this research. Basing on transcriptome information, B. balsamifera flavonoids metabolic pathway was analyzed in KEGG data base. The result demonstrated that two metabolic pathways of flavonoids were found in KEGG data base. They were flavonoid biosynthesis pathway (No.ko00941) that contained 32 genes and flavone and flavonol biosynthesis pathway (No.ko00944) that contained 12 genes. Metabolic pathway of flavonoids in B. balsamifera was similar to that in other plants. Chalcone synthase (CHS) and Chalconeisomerase were much likely to be key enzymes on metabolic pathway of flavonoids in B. balsamifera. HCT was much relevant to biosynthesis of favones.
