Natural and ayurvedic medicines were used by old people prepared from medicinal plants for treatment of diseases. Now a days also, the importance of medicinal plants remain as such due to their efficient way of curing and researchers focus more in the field of medicinal plants. The present investigation has paid attention on one of the important medicinal plants “Andrographis paniculata (Burm. f.) Nees.”, due to presence of its valuable secondary metabolite “Andrographolide”. The common name of Andrographis paniculata is kalmegh. The present study aimed to elucidate the expression of candidate genes associated with biosynthesis pathway leading to andrographolide synthesis in different genotypes of kalmegh at particular vegetative growth stage. The validation of expressed genes was also carried out.en-USnullThesis
