Abstract
Abiotic stress has become a major risk to food security and is predominantly the leading cause of extensive crop and agriculture produce loss worldwide. It has been estimated that about 50% of major agriculture produce is lost due to various abiotic stress factors. Plants perceive risk alarm by virtue of their receptors and activate protective mechanism to sustain against abiotic stresses. These protective mechanisms include accumulation of protective metabolites such as phenolics, terpenes and alkaloids, out of which phenolics play a vital role in the survival of the plant under various abiotic stresses. Enhanced synthesis of phenolics assures the survival, persistence, endurance and competitiveness of the plant against abiotic stress.
