ABSTRACT
Flavonoids are secondary plant metabolites and are required for the proper growth and development of plants. Flavonoids also contribute by providing protection against adverse environmental conditions due to their antioxidant properties. The flavonoid biosynthetic pathway and its regulatory mechanism provide insight through the in-depth understanding of higher accumulation of flavonoid content required for growth and development and improved tolerance under abiotic stresses. The metabolic engineering of a selected set of biosynthetic pathway related genes has been achieved for providing better adaption under environmental constraints. The complied information could be exploited for the advancement of crop improvement programs under adverse environmental conditions by the accumulation of flavonoid contents.
