| Summary: | Strobilanthes crispus is one of Malaysian native medicinal plant that has been reported to possess antioxidant, anticancer and anti-diabetic activities and contains a high level of flavonoids. To date, no work has been reported on the molecular and enzymatic level for the biosynthesis of flavonoids in this plant. Thus, a research with the aim to study for the molecular biosynthesis of flavonoids in this plant was conducted and started by the cloning of chalcone synthase (CHS) gene, the key biosynthetic gene of flavonoids in this plant. RACE (Rapid Amplification of cDNA Ends) Polymerase Chain Reaction was conducted to retrieve the 3' end and 5' end of chalcone synthase gene in order to obtain the whole sequence of Strobilanthes crispus chalcone synthase gene. Although 3' end was successfully been retrieved and give high similarity to chalcone synthase gene from other plants but unfortunately 5' end was failed to retrieve. |
