“…In the previous reports, it has been observed that heavy-metal stress has shown negative impacts on plants’ vital cellular components and functions such as DNA damage, deformation of plant cells, and difference in cellular redox homeostasis, phytohormone contents, biomass, and yield. − In another report, zinc has shown negative effects including phototoxicity, modulation in abiotic response and physiological parameters, reducing photosynthetic pigment concentration, and reduction in root activity of wheat and other plants. − Although plants have their own defense system against heavy-metal stress to resist the change by cellular exudates, membrane integrity, activating heat shock proteins, metallothioneins, and organic acid within certain limits. , But, in the case of accumulation of heavy metals beyond a threshold and traditional strategies such as fertilizers, fungicides, insecticides, pesticides, use of dietaryfibers, and chelating agents are considered inadequate for coping with heavy-metal stress. Therefore, an exciting nanotechnological method of introducing nanomaterials has revolutionized the process of reducing metal stress to a great extent by absorbed heavy metals, reducing stress and enhancing the plant growth without any lethal effects. − Nanotechnology is an emerging technique that is recounting its role in the agricultural field . Nanoparticles, when applied to crop plants, significantly increase the growth of plants under unfavorable environmental circumstances by triggering numerous physiological and biochemical mechanisms occurring in plants. − The small size, active movement, condensed surface area, slow-release, and higher rate of uptake make nanomaterials a good applicant as compared to outdated chemical processes. , It was detected that less mediation of NPs is mandatory that gives marked results when applied on plants as related to common salts.…”
