“…Moreover, studies have shown that Arabidopsis roots, leaves, flowers and harvested seeds treated with CuO NPs contained significantly higher Cu elements than CuO bulk particles (BPs) and Cu 2+ treatment, demonstrating that CuO BPs cannot be readily accumulated and distributed in the plant (Figure 8), indicating that CuO NPs themselves have high mobility in Arabidopsis. In combined ethylene experiments, CuO NPs were observed to induce oxidative stress and inhibit growth by affecting the rosette size, biomass, chlorophyll content, lipid peroxidation, accumulation of oxygen species and cellular ultrastructure of Arabidopsis [38,68]. Interestingly, Jia et al found that the Cys cycle affected the uptake and intracellular transport of CuO NPs.…”

The widespread application of metal-based nanoparticles (MNPs) has prompted great interest in nano-biosafety. Consequently, as more and more MNPs are released into the environment and eventually sink into the soil, plants, as an essential component of the ecosystem, are at greater risk of exposure and response to these MNPs. Therefore, to understand the potential impact of nanoparticles on the environment, their effects should be thoroughly investigated. Arabidopsis (Arabidopsis thaliana L.) is an ideal model plant for studying the impact of environmental stress on plants’ growth and development because the ways in which Arabidopsis adapt to these stresses resemble those of many plants, and therefore, conclusions obtained from these scientific studies have often been used as the universal reference for other plants. This study reviewed the main findings of present-day interactions between MNPs and Arabidopsis thaliana from plant internalization to phytotoxic effects to reveal the mechanisms by which nanomaterials affect plant growth and development. We also analyzed the remaining unsolved problems in this field and provide a perspective for future research directions.

Antimony (Sb) has been reported to be largely taken up and accumulated by plants, although it is unessential for plant growth. The translocation and phytotoxicity of Sb in plant tissues greatly depend on the redox chemistry states. A number of studies have investigated the phytotoxicity of enginered nanoparticles (ENPs) to various vascular plants. However, the coexposure of ENPs with Sb has not been well understood, as well as the potential interactions between ENPs and Sb species relating to their uptake and translocation in plants. In this study, three common metal oxide nanoparticles (CeO 2 , TiO 2 , and CuO NPs, 50 mg L −1 ) with different redox properties were selected and coexposed with Sb (trivalent (III) and pentavalent (V) states, 50 mg L −1 ) to soybean seedlings. The results suggested that the accumulation of Sb(III) in roots was significantly increased by CeO 2 (by 36.7%) and CuO NPs (by 58.8%) respectively, while no significant effects were caused by TiO 2 NPs. In contrast, both Sb(III) and Sb(V) significantly decreased the accumulation of CeO 2 NPs in roots which resulted in only 2.9% and 13.02% of Ce accumulation compared to a single exposure of CeO 2 NPs. However, the accumulations of both TiO 2 NPs and CuO NPs in roots and leaves were significantly increased. In addition, ENPs and Sb displayed mutual antagonism or synergistic effects on plant biomass amounts, malondialdehyde (MDA) contents, and enzyme activities. These results suggested that the potential interactions between Sb species and ENPs and the different impacts of coexposure treatments on soybeans might depend on Sb initial oxidation states and ENPs properties. This study provided another insight to understand the accumulation and transfer of Sb and ENPs in edible plants and human exposure risks in these environments.

“…In a yet recent study, the results of Azhar et al advocated that nCuO adversely affected the Arabidopsis biomass, chlorophyll contents, guard cells, stomatal pore, and various cell organelles, with a consequent increase in the ROS accumulation in all four Arabidopsis genotypes studied. These reports suggested that various NPs had negative impacts on different crop plants [23].…”

The Impact of Priming with Al2O3 Nanoparticles on Growth, Pigments, Osmolytes, and Antioxidant Enzymes of Egyptian Roselle (Hibiscus sabdariffa L.) Cultivar

Lower concentrations of nanoparticles (NPs) could have positive effects on plants. In the present experiment, we tested the efficacy of seed priming Egyptian roselle cultivar with aluminum oxide nanoparticles (Al2O3 NPs). Plants grown with different concentrations (0.01, 0.05, 0.1, and 0.5%) of Al2O3 NPs-primed seeds showed varied responses. An increasing impact with 0.01% Al2O3 NPs was noticed on growth traits, such as fresh weight, dry weight, shoot length, root length, and leaf area, and physio-biochemical activities like chlorophyll a, chlorophyll b, carotenoid contents, soluble sugars, protein, amino acid, proline, and the activities of defense enzymes viz-superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), and ascorbate peroxidase (APX). Nevertheless, a decrease was noted in malondialdehyde (MDA) when plants were primed with 0.01% Al2O3 NPs. Seed priming with 0.05, 0.1, and 0.5% Al2O3 NPs caused the negative effects in the aforementioned parameters. The principal component analysis revealed significant correlations among the various studied parameters. Therefore, seed priming with Al2O3 NPs at 0.01% was expected to serve as an effective measure for inducing positive effect in Egyptian roselle cultivar.
