“…The current findings were consistent with previous studies regarding a dose dependent increase in the amount of Fe in Solanum lycopersicum (Shankramma et al 2016) and Arachis hypogaea (Rui et al 2016) upon exposure to increasing concentrations of iron oxide NPs with average sizes 10 and 20 nm, respectively. However, Marusenko et al (2013) pointed out that Arabidopsis thaliana plants didn't show uptake of hematite NPs (∼40.9 nm) when grown in agar media, suggesting that the failure to obtain NPs may be a possible mechanism for plant survival against NPs toxicity. Furthermore, the current findings showed that the accumulation of hematite NPs in maize roots resulted in a significant reduction in calcium uptake at NPs treatments ranged from 2000 to 8000 mg kg −1 .…”

The present study describes the response of Zea mays to hematite nanoparticles (NPs) using five concentrations ranged from 500 to 8000 mg kg −1 , and Cd 2+ concentrations (110 or 130 mg kg −1 Cd 2+ ) only or combined with 500 mg kg −1 NPs, using soil culture. The endpoints measured were root/shoot growth, elements uptake, ultra-structural alterations, lipid peroxidation, some antioxidant enzyme activities, and their relative gene expressions. The results indicated that hematite NPs exhibited a dual behavior, in which 500 mg kg −1 NPs significantly enhanced maize growth, while 4000 and 8000 mg kg −1 NPs significantly increased lipid peroxidation and superoxide dismutase (SOD) activity displaying positive correlation with SOD expression in shoots (r = +0.472, p < .05). Ultrastructure micrographs revealed the appearance of aggregated NPs inside the vacuoles. The stunted growth, perturbed ultra-structure, and high lipid peroxidation were used as toxicity biomarkers for Cd 2+ . However, combined treatments of 500 mg kg −1 NPs and Cd 2+ significantly stimulated growth and glutathione reductase activity, while significantly reduced catalase (CAT) activity displaying positive correlation with CAT expression in roots (r = +0.694, p < .01). In conclusion, hematite NPs could alleviate Cd 2+ toxicity not at the level of antioxidant defense, but by affecting mechanisms of Cd 2+ detoxification.

“…This positive effect could due to the the greater bioavailability of iron molecules to the seed radicals [13] and the the higher solubility of Fe 2 O 3 NPs in suspension [12]. Notebly, considering the different sizes, morphologies of NPs and differents plants species, the acquisition strategies of Fe elements as the nanoparticulates may not always effective [14]. In our study, Fe 2 O 3 NCs and Fe 2 O 3 SRs had no obvious effect on germination, but Fe 2 O 3 LRs inhibited this crucial index siginificantly.These interesting phenomenon seems can be largely due to the nanomaterials' morphologies.Recently it was reported that AgNPs have higher toxicity than AgNCs and AgNWs, which indicated the influence of nanomaterials on plants [15].…”

“…Previous work on non-GM plants reported negative, positive, and/or no effect of different NPs on seed germination, root elongation, and other plant growth performance indicators. ENPs can influence nutrient uptake (Larue et al 2012;Trujillo-Reyes et al 2013), bioavailability (Lee et al 2008;Marusenko et al 2013), biotransformation (Zhang et al 2012(Zhang et al , 2013, antioxidant enzyme activity (Cui et al 2014;Rico et al 2013), and other physiological biomarkers in conventional plants. Fe 2 O 3 NPs specifically have been shown to have key effects on plants.…”

Nanoparticles (NPs) are an increasingly common contaminant in agro-environments, and their potential effect on genetically modified (GM) crops has been largely unexplored. GM crop exposure to NPs is likely to increase as both technologies develop. To better understand the implications of nanoparticles on GM plants in agriculture, we performed a glasshouse study to quantify the uptake of Fe2O3 NPs on transgenic and non-transgenic rice plants. We measured nutrient concentrations, biomass, enzyme activity, and the concentration of two phytohormones, abscisic acid (ABA) and indole-3-acetic acid (IAA), and malondialdehyde (MDA). Root phytohormone inhibition was positively correlated with Fe2O3 NP concentrations, indicating that Fe2O3 had a significant influence on the production of these hormones. The activities of antioxidant enzymes were significantly higher as a factor of low Fe2O3 NP treatment concentration and significantly lower at high NP concentrations, but only among transgenic plants. There was also a positive correlation between the treatment concentration of Fe2O3 and iron accumulation, and the magnitude of this effect was greatest among non-transgenic plants. The differences in root phytohormone production and antioxidant enzyme activity between transgenic and non-transgenic rice plants in vivo suggests that GM crops may react to NP exposure differently than conventional crops. It is the first study of NPs that may have an impact on GM crops, and a realistic significance for food security and food safety.
