Role of Secondary Metabolites for the Mitigation of Cadmium Toxicity in Sorghum Grown Under Mycorrhizal Inoculated Hazardous Waste Site

Abstract

Apart from the many primary metabolites like carbohydrate, proteins, fats, and hormones, a number of organic compounds in plants are not synthesized in the principle stream, but they are most important for the plant functions. These compounds are secondary metabolites broadly classified in terpenes, alkaloids, and phenols. Nowadays, heavy metal contamination is the greatest concern worldwide. The role of secondary metabolites is well acquainted with facts that it imparts the significant effect in the mitigation of heavy metal toxicity in the plants. The FTIR data of the experiments indicate clearly that phenols, aldehyde, and ketones will play the critical role in the regulation of heavy metal toxicity in plants.
