“…The diverse behavior of NPs also makes them viable for developing nanopesticides, nanoherbicides, and nanosensors for plant, soil, and pest monitoring in an intelligently controlled environment, a trend in agriculture 4.0 ( Kah et al., 2019 ; Rastogi et al., 2019 ; Shawon et al., 2020 ). However, some of the mentioned physical and chemical characteristics are also related to phytotoxicity, potential environmental toxicity, and human health hazards ( Paramo et al., 2020 ; Ayub et al., 2022 ), which involves mandatory experimentation to find the appropriate doses, exposure times, and types of NP types for every crop.…”

“…Climate change, water deficit, low nutrient use efficiency, crop pests, and decreasing availability of land for crop development, combined with the increasing demand for food due to a growing world population, require the sustainable development of agriculture ( Seleiman et al., 2021 ; Ayub et al., 2022 ; Gil-Díaz et al., 2022 ). The efficient use of natural resources without negative repercussions to the environment has encouraged the incursion of new technologies, such as nanotechnology to provide viable alternatives in diverse areas, including agriculture.…”

The efficient use of natural resources without negative repercussions to the environment has encouraged the incursion of nanotechnology to provide viable alternatives in diverse areas, including crop management. Agriculture faces challenges due to the combination of different abiotic stresses where nanotechnology can contribute with promising applications. In this context, several studies report that the application of nanoparticles and nanomaterials positively affects crop productivity through different strategies such as green synthesis of nanoparticles, plant targeted protection through the application of nanoherbicides and nanofungicides, precise and constant supply of nutrients through nanofertilizers, and tolerance to abiotic stress (e.g., low or high temperatures, drought, salinity, low or high light intensities, UV-B, metals in soil) by several mechanisms such as activation of the antioxidant enzyme system that alleviates oxidative stress. Thus, the present review focuses on the benefits of NPs against these type of stress and their possible action mechanisms derived from the interaction between nanoparticles and plants, and their potential application for improving agricultural practices.

“…The rapidly increasing use of nanoparticles in diverse fields of electronics, pharmaceuticals, cosmetics, agriculture, and remediation technologies has created some serious concerns regarding their fate in the environment ( Moraru et al., 2003 ; Ayub et al., 2022 ; Umar et al., 2022 ). The widespread application of nanoparticles has created many point and non-point sources of pollution, which can become a concern if they continue to be unchecked as metallic nanoparticles are a major class of these potential pollutants ( Kurwadkar et al., 2015 ; Sohail et al., 2021 ).…”

IntroductionThe increasing use of cerium nanoparticles (CeO2-NPs) has made their influx in agroecosystems imminent through air and soil deposition or untreated wastewater irrigation. Another major pollutant associated with anthropogenic activities is Cd, which has adverse effects on plants, animals, and humans. The major source of the influx of Cd and Ce metals in the human food chain is contaminated food, making it an alarming issue; thus, there is a need to understand the factors that can reduce the potential damage of these heavy metals.MethodsThe present investigation was conducted to evaluate the effect of CeO2-10-nm-NPs and Cd (alone and in combination) on Zea mays growth. A pot experiment (in sand) was conducted to check the effect of 0, 200, 400, 600, 1,000, and 2,000 mg of CeO2-10 nm-NPs/kg-1 dry sand alone and in combination with 0 and 0.5 mg Cd/kg-1 dry sand on maize seedlings grown in a partially controlled greenhouse environment, making a total of 12 treatments applied in four replicates under a factorial design. Maize seedling biomass, shoot and root growth, nutrient content, and root anatomy were measured.Results and discussionThe NPs were toxic to plant biomass (shoot and root dry weight), and growth at 2,000 ppm was the most toxic in Cd-0 sets. For Cd-0.5 sets, NPs applied at 1,000 ppm somewhat reverted Cd toxicity compared with the contaminated control (CC). Additionally, CeO2-NPs affected Cd translocation, and variable Ce uptake was observed in the presence of Cd compared with non-Cd applied sets. Furthermore, CeO2-NPs partially controlled the elemental content of roots and shoots (micronutrients such as B, Mn, Ni, Cu, Zn, Mo, and Fe and the elements Co and Si) and affected root anatomy.
