Food safety has occurred as a high-urgency issue for sustainable agricultural production. Heavy metal (HM)/metalloid toxicity in soil and water substantially impacts productivity, which is beyond heightened by intense anthropogenic activities innovative systems, putting food human health at threat. Other than lowering crop production, enhanced HM also distracts plant's needs resource stability. Compensating requires better knowledge of the intricate mechanisms physiological, biochemical, molecular, cellular, plant level that may rise improved productivity. Therefore, plants have set up various internal defense against adverse consequences HMs. Nonetheless, these are insufficient to devastate toxicity. Plants generate numerous secondary messengers activate cell signaling, activating several transcriptional responses connected with defense. Hence, recent improvements omics approaches, instance, genomics, transcriptomics, proteomics, metabolomics, miRNAomics, phenomics, allowed characterization molecular regulators interrelated tolerance. This chapter highlights Further, multi-omics approaches been presented identify stress-related key enhance tolerance plants.
