“…Pathogenesis-related proteins are over-expressed following pathogen attack or stress. Our results confirmed the long-lasting effect of the field applied treatments on the expression of the defense-related genes that is supported by the results recorded in table grapes [40], jujube fruits [44], apple [19,45], common beans [26,46], and in tomatoes and sweet peppers [14,15]. The present study suggests that the exogenous application of chitosan NPs or bulk form could effectively induce strong systemic acquired resistance (SAR) against P. expansum infection in apples (cv.…”

Blue rot disease caused by Penicillium expansum is one of the most widespread fungal diseases that affects apples worldwide. This work was to verify the effect of chitosan (2 and 4 g/L) and its nano-form (0.2 and 0.4 g/L) against blue rot disease on apples and their effect on the expression of six defense-related genes as well as fruit quality parameters. Regarding disease incidence, in most cases, chitosan NPs performed better as compared to their raw materials for both artificial and natural infections. The highest efficacy was obtained for chitosan NPs at 0.4 g/L for artificial and natural infection in both 2019 and 2020 seasons. All treatments kept fruit quality parameters regarding firmness, total soluble solids, and titratable acidity for artificial and natural infection in both seasons. As expected, the exogenous application of chitosan NPs and bulk form triggered an increase in the expression levels of six defense-related genes including chitinase, peroxidase, β-1,3-glucanase, Xyloglucan endotransglycosylase (XET), pathogenesis-related protein (PR8), and phenylalanine ammonia lyase-1 (PAL1). Moreover, the highest mRNA quantity of all the studied genes was detected in leaves treated with chitosan NPs at both concentrations compared to other treatments. Chitosan NPs can be considered an eco-friendly and effective approach against blue mold of apples and can be integrated into management programs to maintain postharvest quality and extend the shelf life of fruits.

“…Nanotechnology is employed in agriculture to boost food production, nutritious value, quality, and safety. Low-cost, environmentally friendly NPs can help plants resist disease [26]. Systemic acquired resistance (SAR) is one of plant's defense responses when facing attack by different pathogens that threaten plant production and survival.…”

“…The application of nanomaterials in agriculture has garnered widespread interest. Previous study showed that about 63–91% of the nanomaterials ended up in landfills, 8–28% in soils, and nanomaterials in the atmosphere get deposited on the surfaces of land and water. , Nearly 9% of nanoproducts are used in agricultural nanomaterials and nanocides; copper oxide nanoparticles (CuO NPs) are widely used in agricultural fungicides due to their bacteriostatic properties. − CuO NPs have been demonstrated to be considerably effective in controlling plant diseases as they cause mechanical damage to cell biofilm development, which is toxic to bacteria. − In addition, CuO NPs are considered to be one of the most essential engineered NPs; the growing use and demand for recycled waste water for irrigation has opened up the possibility of releasing CuO NPs into paddy soil via waste water. , CuO NPs are also used as plant growth promoters to enhance the uptake of iron (Fe), calcium, magnesium, and phosphorus in agriculture. , Although CuO NPs are generally recognized as safe salts (GRAS, the FDA’s safety index for food additives), a high dose of CuO NPs (50–1000 mg kg –1 ) significantly increased excessive oxidative stress, inhibited root growth, and decreased the crop yield. − Therefore, the extensive or large-scale use of CuO NPs in paddy soil requires further studies.…”

Copper oxide nanoparticles (CuO NPs) are widely used as fungicides in agriculture. Arsenic (As) is a ubiquitous contaminant in paddy soil. The present study was focused on the adsorption behavior of CuO NPs with regard to As as well as the characteristics of the microbial community changes in As-contaminated soil–rice systems in response to CuO NPs. The study found that CuO NPs could be a temporary sink of As in soil; a high dose of CuO NPs promoted the release of As from crystalline iron oxide, which increased the As content in the liquid phase. The study also found that the As bioavailability changed significantly when the dose of CuO NPs was higher than 50 mg kg–1 in the soil–rice system. The addition of 100 mg kg–1 CuO NPs increased the microbial diversity and the abundance of genes involved in As cycling, decreased the abundance of Fe(III)-reducing bacteria and sulfate-reducing genes, and decreased As accumulation in grains. Treatment with 500 mg kg–1 CuO NPs increased the abundance of Fe(III)-reducing bacteria and sulfate-reducing genes, decreased Fe plaques, and increased As accumulation in rice. The adverse effects of CuO NPs on crops and associated risks need to be considered carefully.

“…Nanomaterials are used in many fields because of the remarkable enhancement of optics, mechanics, electricity, structure, and magnetism of nanomaterials [ 1 ]. Copper oxide nanoparticles (CuO NPs) are widely used as a fungicide in agriculture because of their destructive effect on bacteria and fungi at both the cellular level and the molecular level [ 2 , 3 ]. In addition, CuO NPs are used as a plant growth promoter in agriculture when soil is infected by pathogenic bacteria [ 4 , 5 ].…”

Copper oxide nanoparticles (CuO NPs) are widely used as a fungicide in agriculture. The application of CuO NPs in agriculture affects the growth of rice and metal accumulation in rice. However, the mechanism of CuO NPs on arsenic (As) accumulation in rice remains unclear. In this study, a hydroponic culture was produced to investigate the mechanism of the effect of 50 and 100 mg L−1 CuO NPs on As accumulation in rice. Our results showed that CuO NPs decreased As(III/V) accumulation in the roots and shoots by adsorbing As(III/V), oxidizing of As(III) on the surface, and thickening the root cell wall. The addition of CuO NPs regulated the expression of the OsNIP1;1, OsHAC1;1, and OsHAC4 genes, which decreased As(III) transport and promoted As(V) reduction in the roots. Moreover, when CuO NPs were co-exposed to As, a negative correlation between the concentration of Cu and As in rice was also found in our study. However, CuO NPs significantly increased Cu accumulation in rice and constrained the rice growth. In conclusion, CuO NPs might be a promising way to decrease As accumulation in rice, but the negative effects such as growth inhibition should be further considered. Therefore, the application of CuO NPs in rice plants should take a more restrained approach.
