Description

Plants are invariably subjected to various environmental stresses that hinder their normal growth and development, which leads to decreased plant productivity and yield. To combat the detrimental effects of such abiotic and biotic stresses, plants have developed diverse mechanisms and one of the prominent ones includes the production of secondary metabolites like phenolic, alkaloids, terpenes, etc. Secondary metabolites serve as major components of the plant stress responses. Chalcones (1,3-diaryl-2-propen-1-one) and coumarins (1,2-benzopyrone) are precursors of flavonoids, a common secondary metabolite of plants that provide a beneficial role during oxidative and biotic stress. Apart from protection, coumarins have certain roles in promoting or inhibiting plant growth, affecting cell division and differentiation and auxin metabolism. These compounds are also known to possess therapeutic properties such as anti-inflammatory, anti-microbial, anti-cancer, and cytotoxic effects when isolated from plants. Besides, chalcones and coumarins have allelopathic effects and protect plants against herbivory. Owing to excellent ROS scavenging properties, chalcones, coumarins, and their derivatives are extensively employed as agents to alleviate adversities associated with abiotic stresses like osmotic, heat, and cold stress, and in defense against pathogen invasion. The application of these secondary metabolites to mitigate atrocities of environmental stress in plants is an interesting and concurrent area of investigation. This chapter highlights the structural and functional details of chalcones and coumarins and their implications in ameliorating environmental stress in plants. 2024 Apple Academic Press, Inc.
