Optimization of Flavonol Synthase (FLS) gene amplification from Melastoma decemfidum via PCR

Flavonol synthase (FLS) converts dihydroflavonol (dihydroquercetin and dihydrokaempferol) to flavonol (quercetin and kaempferol) in flavonoid biosynthetic pathway. Leaves and flower extracts of Melastoma decemfidum are rich in flavonoids and possess strong antioxidant and antitumor activities. In th...
