“…In the same study, n CuO treatment induced a positive effect on rice biomass only at a low level (50 mg/kg) . Comparable results were reported in another study: hydroponic exposure to n CuO for 7 days enhanced rice seedling growth at lower dosages (5, 10, 20, and 50 μM) and significantly reduced it at higher concentrations (100, 200, and 500 μM), probably due to the enhancement of oxidative stress . Moreover, hydroponic exposure to n CuO at 100 mg/kg for 6 days was found to alleviate As toxicity by reducing the level of accumulation of As(III) in rice seedling tissues …”

The application of nanotechnology in the field of agriculture as nanofertilizers or nanopesticides is receiving increased attention from regulatory agencies and research institutions worldwide. Soil and bodies of water are among the most massive sinks for commercial products containing engineered nanoparticles (ENPs) after use. This may affect agricultural ecosystems, mainly those with a high demand for irrigation water supply such as rice (Oryza sativa L.) cultivars. This review describes the responses of different rice cultivars exposed to ENPs at different growth stages and under different conditions. Data on seed germination, uptake and translocation of ENPs, biomass production, nutrient profiles, and photosynthesis-related parameters are discussed. Critical knowledge gaps concerning the potential use of nanotechnology to improve agricultural production are highlighted.

An emerging field of science “Nanotechnology” which is involved in manipulation of atoms and molecules has shown great potential in all fields of sciences. Nanotechnology deals with nanoparticles ranging from size 1 to 100 nm in diameter, due to small size and high surface area eventually increases the state of activity. This review focuses on metal and metal oxide nanoparticles and mainly on green synthesis, characterization and application of copper nanoparticles. Green synthesis of copper and copper oxide (Cu and CuO) is economically beneficial and ecofriendly. Copper nanoparticles are used in diverse fields such as biomedicine, pharmaceuticals, bioremediation, molecular biology, bioengineering, genetic engineering, dye degradation, catalysis, cosmetics and textiles. Structural properties and biological effects of copper nanoparticles have promising effectivity in field of life sciences.

“…CuO NPs inhibit plant growth by accumulating in the non-ionic form in chloroplasts (Da Costa et al 2020). CuO NPs toxicity impairs root development, uptake of water and nutrients in plants, thereby constraining crop growth and yield (Ahmed et al 2018;Tiwari et al 2019). Under NPs stress, growth and biomass of mung bean, cucumber, wheat and rice were significantly inhibited (Nair et al 2014;Mosa et al 2018;Rastogi et al 2019).…”

Copper oxide nanoparticles (CuO NPs) show strong nano‐toxic effects on organisms. Hydrogen sulphide (H2S) plays a pivotal role in plant response to abiotic stress. In this study, we examine the crucial role of the cell wall as regulated by H2S in response to CuO NPs stress. The digestion method was employed to determine Cu content using atomic absorption spectrometry. The TraKine pro‐tubulin staining kit was used to investigate the microtubule cytoskeleton using confocal laser‐scanning microscopy. Cell wall component analysis utilized the ICS‐3000 HPLC system. Application of H2S reduced growth inhibition caused by CuO NPs. Furthermore, most of the CuO NPs accumulates in roots, indicating a low transfer rate, and H2S significantly decreased CuO NPs content in roots, leaves and stems. Subcellular distribution analysis implied most Cu accumulated in root cell walls, and that H2S reduced the content of Cu in root cell walls. Cortical microtubules in the plasma membrane, guide cell wall biosynthesis. H2S obviously alleviated microtubule cytoskeleton disorders caused by CuO NPs. In addition, the content of cellulose, hemicellulose, pectin and other monosaccharides in root cell walls was reduced by CuO NPs treatment. H2S enhanced the monosaccharide and polysaccharide contents compared with that after CuO NPs treatment. In conclusion, H2S regulates cell wall development in response to CuO NPs stress by stabilizing microtubules. H2S affected Cu distribution and alleviated growth inhibition of tomato seedlings. The research results provide a theoretical basis for further study of nano‐toxicity regulation in plants.
