“…(2018) showed that growing wheat in selenium-rich soil reduces the content of toxic metals such as Ni and Pb in roots and shoots. Zinc oxide (ZnO) nanoparticles prevented the adverse effects of cadmium stress in the plant but caused the accumulation of Cd in the root and stem tissues of mung beans ( Rashid et al., 2022 ).…”

Biofortification is the supply of micronutrients required for humans and livestock by various methods in the field, which include both farming and breeding methods and are referred to as short-term and long-term solutions, respectively. The presence of essential and non-essential elements in the atmosphere, soil, and water in large quantities can cause serious problems for living organisms. Knowledge about plant interactions with toxic metals such as cadmium (Cd), mercury (Hg), nickel (Ni), and lead (Pb), is not only important for a healthy environment, but also for reducing the risks of metals entering the food chain. Biofortification of zinc (Zn) and selenium (Se) is very significant in reducing the effects of toxic metals, especially on major food chain products such as wheat and rice. The findings show that Zn- biofortification by transgenic technique has reduced the accumulation of Cd in shoots and grains of rice, and also increased Se levels lead to the formation of insoluble complexes with Hg and Cd. We have highlighted the role of Se and Zn in the reaction to toxic metals and the importance of modifying their levels in improving dietary micronutrients. In addition, cultivar selection is an essential step that should be considered not only to maintain but also to improve the efficiency of Zn and Se use, which should be considered more climate, soil type, organic matter content, and inherent soil fertility. Also, in this review, the role of medicinal plants in the accumulation of heavy metals has been mentioned, and these plants can be considered in line with programs to improve biological enrichment, on the other hand, metallothioneins genes can be used in the program biofortification as grantors of resistance to heavy metals.

“…Antioxidant enzymes were upregulated by ZnO NPs in order to prevent oxidative stress and preserve growth performance. (Rashid et al, 2022) ZnO nanoparticles decreased carotenoid contents in maize leaves Chlorophylls, proteins, DNA, and lipids are among the cellular constituents that carotenoids are crucial in preventing oxidative damage to and capturing radical oxygen species. (Hashemi et al, 2019) One of the most frequent stress responses to heavy metal exposure in plants is the production of reactive oxygen species (ROS), which can alter metabolism through oxidative cell damage (Venkatachalam et al, 2017).…”

Heavy metal pollution is the one of the most important factors that limit the growth and yield of faba bean plants in the world. In recent years, nanotechnology has showen promising result in reducing the harmful effects of heavy metal stress on various crops such as peas (Pisum sativum), faba beans (Vicia faba leguminosae). This experiment aimed to study the effect of foliar spray of zinc nanoparticles (ZnO NPs) at two concentrations (100 and 200 ppm) on the growth parameters shoot length, root length, fresh and dry weight of shoots and roots, and leaf area of faba bean plants. In addition, the content of chlorophyll and carotenoids were measured under Cd stress (20 and 100 ppm). The samples were collected twice, 15 and 30 days after treatments. The results showed that Cd had adverse effects on shoot and root lengths, shoot fresh and dry weights, root fresh and dry weights, and leaf area. The treatment with ZnO NPs significantly reduced the side effects of Cd on the level of growth parameters at two stages. ZnO NPs 200 was more effective than ZnO NPs 100. From our results, ZnO NPs can be used to mitigate the Cd stress in agricultural soils.

“…Nanoparticles are found to be very toxic to different plant species [46], while they play a crucial role in promoting plant growth in others [47,48]. Zinc is known to be involved in controlling enzymes, protein synthesis, cell elongation, regulating membrane function, and increasing plant tolerance to environmental stress [49], and high Zn content in seeds could act as a seed germination starter and promote early seedling growth by speeding up metabolism [50][51][52]. Muhammad et al [53] demonstrated that ZnO nanoparticle priming increased Zn content in maize seed embryo tissues and aleurone layers.…”

Zinc oxide (ZnO) particles have recently received attention in different agriculture sectors as new technologies and practices are entering into force with limited adverse effects on the environment. However, various works have reported both positive or negative effects on plants. The present study focused on an evaluation of the effects of four different new micro- and nano-sized ZnO particles (namely, Desert Roses (DRs), MultiPods (MPs), NanoFlakes (NFs), and NanoParticles (NPs)) on the seed germination traits of Ocimum basilicum L., Lactuca sativa L., and Lepidium sativum L. ZnO particles were applied at concentrations of 12.5 ppm, 25 ppm, and 50 ppm. Seeds moistened with deionized water were used as a control. All the particles were characterized by field emission scanning electron microscopy, and their production of Reactive Oxygen Species (ROS) under seed germination conditions was evaluated through electron paramagnetic resonance spectroscopy. Seeds of each species were put on filter paper under controlled conditions in both dark and light photoperiods. In this bioassay, the final germination percentage (FGP), early root length, and index of germination were evaluated. The results showed a wide variability of response to the type and concentration of ZnO particles and to the applied photoperiod of the three studied species. O. basilicum FGP increased when treated with NPs and DRs already at the lowest concentration and especially in light conditions with values significantly superior to those of the control (71.1%, 69.4%, and 52.2%, respectively). At higher concentrations, phytotoxicity on root length was observed, with a reduction of circa 30% in comparison to untreated seeds. On the contrary, in L. sativum, a phytotoxic effect was seen in radicle length with all the used ZnO particles and concentrations. L. sativa seeds did not show significant effects due to the type of particles, with a reduction in FGP only at higher concentrations and particularly in light conditions. Upon light irradiation, different levels of ROS were counted by the application of ZnO particles. DRs produced the highest amount of DMPO-OH adduct (up to 2.7 × 10−5 M) followed by the NP type (2.0 × 10−5 M). Taking together all these findings, the seeds’ coat morphology, their ability to absorb ZnO particles, and the ROS production in light conditions are indeed crucial players in the application of these formulations in seed germination.
