The role of zinc oxide nanoparticles (ZnO NPs) in plants and agriculture attracted huge interests during the last few years. A whole range of positive of NPs has been demonstrated and these exquisite material can be serve as alternatives to many fertilizers, micronutrients, fungicides or antimicrobial chemicals. The ameliorative roles against abiotic stress (drought, salinity and high temperature) in various crops are particularly significant. However, high concentrations of ZnO NPs have been observed to produce a range of toxicity including growth/yield inhibition, physiological aberrations, cytotoxicity, genotoxicity and oxidative stress. The positive or negative effects depend on the type, dose of nanomaterials, methods of treatments, developmental stage, and genotype of the species or environmental conditions. Until a fuller understating of various modes of interactions between ZnO NPs and plant genome or epigenome develops, it is difficult to use these new resources for the optimal benefit, substituting conventional agents of growth promotion or protection. This requires development of appropriate methods to identify plant conditions and optimize the nanomaterial treatment.
