The unprecedented capability to control and characterize materials on the nanometer scale has led to the rapid expansion of nanostructured materials. The expansion of nanotechnology, resulting into myriads of consumer and industrial products, causes a concern among the scientific community regarding risk associated with the release of nanomaterials in the environment. Bioavailability of excess nanomaterials ultimately threatens ecosystem and human health. Over the past few years, the field of nanotoxicology dealing with adverse effects and the probable risk associated with particulate structures <100 nm in size has emerged from the recognized understanding of toxic effects of fibrous and non-fibrous particles and their interactions with plants. The present review summarizes uptake, translocation and accumulation of nanomaterials and their recognized ways of phytotoxicity on morpho-anatomical, physiological, biochemical and molecular traits of plants. Besides this, the present review also examines the intrinsic detoxification mechanisms in plants in light of nanomaterial accumulation within plant cells or parts.
•MNPs induce alterations in morpho-anatomical, physiological, biochemical and molecular traits in plants.•Toxicity of nanoparticles on plants depends on various factors, specifically the size of NP, shape, use of carrier, coating and experimental methods.•Nanoparticles are capable of inducing up and/or down-regulation of the marker genes, water transport (aquaporin), formation of the cell wall and the cell division.•The current status and future prospects of MNPs interaction with plants has been discussed.
