Plant growth regulator mediated consequences of secondary metabolites in medicinal plants

Secondary metabolites not only play vital role in plant defense against herbivory and other interspecies defenses but also used by humans as medicines, flavorings, pharmaceuticals, agrochemicals, fragrances, colours, biopesticides, food additives and drugs. Many of the drugs retailed today are simple synthetic modifications of the naturally obtained substances. The developing commercial status of secondary metabolites in recent years has resulted in a great interest in secondary metabolism. Different strategies have been extensively studied with the objective of improving the production of secondary metabolites in plants. Based on this limelight, the focus of the present review is to study the application of plant growth regulators for the production of some essential plant secondary metabolites. This review covers brief introduction of secondary metabolites and plant growth regulators and production of secondary metabolites by using different plant growth regulators according to their classification.
