“…Furthermore, the nanoformulation could increase the bioavailability of soil nutrients to be absorbed by the plant root. The photosynthesis of Spinacia oleracea plants was enhanced when the soil was treated with CuO NPs at 200 mg/kg concentration after 60 days of application [63]. Along with the benefits offered by the nanoformulation as an herbicide in seed germination and foliar application, it significantly promoted the total chlorophyll and carotenoids in the soil application.…”

Copper nanoparticles were synthesized via a bioreduction using sulfated polysaccharides (SPs) extracted from Avicennia marina mangrove leaves and their phytotoxicity effect on wheat (Triticum aestivum L.) seedlings was assessed. As analyzed by high-performance liquid chromatography (HPLC), SPs extract constituted mainly 49.3% glucose, 24.6% galactose and 20.5% glucouronic acid by mol. A nanoformulation of ultrafine Cu2O/Cu(OH)2 nanoparticles coated with SPs (Cu NPs) was prepared with an average particle size of 2.11 ± 0.64 nm and a slightly negatively-charged zeta potential of 11 ± 0.46 mV. Applying high concentrations of Cu NPs on wheat seeds inhibited the respective shoot and root relative growth percentages, yielding 13.22 ± 9.91 and 36.72 ± 18.51% at 0.06 mg/mL of the nanoformulation. Comparable values were obtained when the seeds were subjected to 0.06 mg/L of SPs extract applied in the free form. In a foliar application, 0.06 mg/mL of Cu NPs reduced the respective total chlorophyll and carotenoids contents by 17.4% and 24.3% relative to the control while the treatment with SPs reduced them by slightly higher values of 27.9% and 32.6%, respectively, after 14 days of application. Therefore, Cu NPs show a comparable inhibition effect to that of the free SPs extract but offer the additional advantages of nanoformulations. In soil applications, however, Cu NPs stimulated the growth of wheat seedlings in contrary to SPs and increased the total chlorophyll and carotenoids by 49.76% and 70%, respectively. This gives an additional merit to the nanoformulation that can potentially be used as an effective biostimulant in soil.

“…Foliar spraying of Nano Fe significantly increase protein content in Phaseolus vulgaris (Jahanara et al 2013). Wang et al (2019) Reported that the application CuO-NPs mixed with the soil were no significant change in Chl a content, intercellular CO 2 concentration or photosynthetic rate in leaves of lettuce while Cu-NPs @ 200 mg/kg were found Chl b in the lettuce leaves is decreased as compared with control. Cao et al (2018) revealed that the chlorophyll pigments were severely reduced by the excessive Cu (120 μM as CuSO 4 ) resulting the lower stomatal conductance and photosynthetic rate.…”

Nano materials are used in practically every aspect of modern life, including agriculture. The conventional fertilizer is replacing by nano fertilizer due to its less quantity required for plant growth and development. Copper and Iron elements are essential micronutrient for plant. Nano Cu and Fe are playing an important role for various attributes such as growth yield, quality, and biochemical parameter. Late blight of potato caused by fungus activity of Phytophthora hence antifungal activity and phytotoxicity improved by the nano Cu. Enzymatic activity (ascorbate peroxidase (APX), catalase (CAT), superoxide dismutase (SOD), glutathione reductase (GR), and lipid peroxidation) and photosynthesis component (chlorophylls a, b and carotenoids) of plant are much influenced by application of Nano Cu and Fe.

“…To elucidate if the morphological and nuclear alterations of the gametogenesis of S. cerevisiae induced by CdS QDs were specific for these ENMs, the same sporulation assay was also carried out using other metal-based nanoparticles characterized by different chemical compositions, sizes, and zeta potentials (Figure S1): ZnS QDs, to evaluate QDs with a different metal composition; CuO NPs, to evaluate ENMs with potential applications from biomedicine to agriculture [34][35][36], but for which several studies have reported toxicity in different organisms [37][38][39]; and CeO2 NPs, to evaluate ENMs with very low toxicity, which in yeast have been shown to inhibit toxicity induced by α-synuclein in a yeast model of Parkinson's disease [40]. We have observed that even at much higher doses than those used for CdS QDs, none of these ENMs significantly affected the sporulation process in S. cerevisiae (Figure 4).…”

Cadmium Sulfide Quantum Dots Adversely Affect Gametogenesis in Saccharomyces cerevisiae

In the last decades, nanotechnology-based tools have attracted attention in the scientific community, due to their potential applications in different areas from medicine to engineering, but several toxicological effects mediated by these advanced materials have been shown on the environment and human health. At present, the effects of engineered nanomaterials on gametogenesis have not yet been well understood. In the present study, we addressed this issue using the yeast Saccharomyces cerevisiae as a model eukaryote to evaluate the effects of cadmium sulfide quantum dots (CdS QDs) on sporulation, a process equivalent to gametogenesis in higher organisms. We have observed that CdS QDs cause a strong inhibition of spore development with the formation of aberrant, multinucleated cells. In line with these observations, treatment with CdS QDs down-regulates genes encoding crucial regulators of sporulation process, in particular, the transcription factor Ndt80 that coordinates different genes involved in progression through the meiosis and spore morphogenesis. Down-regulation of NDT80 mediated by CdS QDs causes a block of the meiotic cell cycle and a return to mitosis, leading to the formation of aberrant, multinucleated cells. These results indicate that CdS QDs inhibit gametogenesis in an irreversible manner, with adverse effects on cell-cycle progression.
