“…In the current study, we provided direct evidences that nano-Cu o priming could enhance drought tolerance in maize, indicated by greater leaf water status ( Figure 3A), chlorophyll and carotenoid contents ( Figure 3B; Table 1), increased anthocyanin accumulation ( Figure 3C) and SOD and APX activities to detoxify the exceed ROS (Figure 4), which may contribute to maintain the photosynthesis and protective mechanism, leading to a growth balancing and drought stress response, could finally contribute to affect plant biomass (Figure 1 (Figure 1; Supplementary S1). These results were supported by previous studies that Cu plays an important role in plant growth and development, and plant productivity (Karamanos et al 2004;Ngo et al 2014;Tamez et al 2019;Xue et al 2014). In the present study, the higher plant biomass found in nano-Cu o priming plants indicated the reduction of drought effect on maize, which was associated with the higher water status of leaf in nano-Cu o group ( Figure 1C-D and 3A; Supplementary Figure 1).…”

“…Support to this hypothesis, our data showed higher chlorophyll contents in nano-Cu o priming plants than those in water-treated plants during drought stress condition (Table 1). Chlorophylls located in chloroplasts have crucial function in photosynthesis system, which highly correlate with plant biomass and recover ( Figure 1) and productivity ( Figure 2) (Karamanos et al 2004;Regier et al 2015;Tamez et al 2019;Yamauchi 2018).…”

Abiotic stresses, including drought, detrimentally affect the growth and productivity of many economically important crop plants, leading to significant yield losses, which can result in food shortages and threaten the sustainability of agriculture. Balancing between plant growth and stress responses is one of the most important characters for agricultural application to maximize plant production. In this study, we initially report that copper nanoparticle priming positively regulates drought stress responses in maize. The copper nanoparticle priming plants displayed enhanced drought tolerance indicated by their higher leaf water content and plant biomass under drought as compared with water-treated plants. Moreover, our data showed that the treatment of copper nanoparticle on plants increased anthocyanin, chlorophyll and carotenoid contents compared to water-treated plants under drought stress conditions. Additionally, histochemical analyses with nitro blue tetrazolium and 3,3'-diaminobenzidine revealed that reactive oxygen species accumulation of priming plants was decreased as a result of enhancement of reactive oxygen species scavenging enzyme activities under drought. Furthermore, our comparative yield analysis data indicated applying copper nanoparticle to plant increased total seed number and grain yield under drought stress conditions. Our data provided the evidences that copper nanoparticle regulates plant protective mechanisms associated with drought tolerance, which is a promising approach for the production of drought tolerant crop plants.

“…Antioxidant enzymes such as CAT, APX, SOD and glutathione reductase are activated by CuNPs as reported in many plant species such as Brassica napus [50], Brassica juncea [51], Cucumis sativus [52], Oryza sativa [53] and Saccharum officinarum [56]. Zhao et al [57] reported that in Zea mays , expression of genes for antioxidant enzymes, POD 1 and GST 1 increased significantly at a Cu(OH) 2 nanopesticide dose of 10 mg but declined at 100 mg. CATs dismutase H 2 O 2 to H 2 O and O 2 while the SODs catalyse the conversion of superoxides to H 2 O 2 .…”

The study aims to document the effect of starch-stabilised copper-based nanoparticles (CuNPs) on the biosynthesis of pharmaceutically valuable secondary metabolites, especially saponins, of the reputed nootropic herb Bacopa monnieri (L.) Pennell. CuNPs were synthesised chemically by the reduction of cupric sulphate pentahydrate with ascorbic acid using starch as the capping agent. They were characterised by UV-visible spectrophotometry, Fourier-transform infra-red spectroscopy, Xray diffraction, high-resolution transmission electron microscopy and zeta potential. The nanoparticles consisted of cuprous oxide and metallic copper, were approximately spherical, polydispersed with diameter <20 nm. Hydroponically grown B. monnieri plants were treated in vivo with the CuNPs between the concentrations of 0-100 mg l −1. Spectrophotometric estimation of the total contents of saponins, alkaloids, phenolics, flavonoids and DPPH radical scavenging capacity from the methanolic extracts of the whole plants showed a hormetic increase in the content of secondary metabolites in a concentration-dependent manner from 5 mg l −1 until it declined at toxic metabolic concentration. This was accompanied by an increase in ROS markers hydrogen peroxide and malondialdehyde as well as a hormetic effect on activities of phenylalanine ammonia lyase and antioxidant enzymes catalase, ascorbate peroxidase and superoxide dismutase. CuNPs at sub-toxic concentrations were found to enhance secondary metabolism and antioxidant capacity in Bacopa monnieri through ROS-mediated defence response. 2 Materials and methods 2.1 Synthesis of copper nanoparticles Starch-stabilised copper nanoparticles were synthesised by the chemical method of Dinda et al. [17] with slight modifications. 1.25 g starch was dissolved in 15 ml double distilled water by

BACKGROUND: Green-tea-synthesized copper oxide nanoparticles (CuO NPs) and S-nitrosoglutathione (GSNO), a nitric oxide (NO) donor, were applied individually and in combination to lettuce leaves. We aimed to investigate whether a combined application of CuO NPs and GSNO might enhance plant growth when compared to individual treatments and the control group. RESULTS: Spherical CuO NPs (13.4 ± 0.1 nm) at 50 ∼g mL −1 and/or GSNO at 100 ∼mol L −1 were individually and simultaneously sprayed onto lettuces leaves. All treatments had a positive effect on plant growth, and the administration of CuO NPs + GSNO promoted a threefold increase in lettuce dry weight. The treatments did not change plant transpiration, and all treatments enhanced instantaneous carboxylation efficiency compared to control. In the roots, all treatments enhanced the levels of S-nitrosothiol in the following order: CuO NPs < GSNO < CuO NPs + GSNO. Administration of GSNO significantly increased total phenolic content (twofold) and flavonoid content (fourfold) compared to the control group. All treatments increased the leaf levels of K, Na, Ca, Mg and S compared to the control group. CONCLUSION: All treatments promoted positive effects on lettuce growth, and no oxidative damage was observed, under the experimental conditions evaluated. A combined administration of CuO NPs and GSNO enhanced important physiological, biochemical and nutritional parameters of lettuces.
