“…Several studies have shown to improve growth and increase in secondary metabolites of plants when chitosan poly-vinyl hydrogel (Cs-PVA) and copper nanoparticles (CuNPs) combined (Hernández-Fuentes et al, 2017;Juárez-Maldonado, Ortega-Ortíz, Pérez-Labrada, Cadenas-Pliego, & Benavides-Mendoza, 2016;Pinedo-Guerrero et al, 2017). Cs-PVA + CuNPs treatment improved the salinity stress by increasing the content of phenols, β-carotene, vitamin C, and lycopene contents.…”

“…Similarly, Cs-PVA+CuNPs increased the defense gene expression, enzyme activity of superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), glutathione peroxidase (GPX) and phenylalanine amino lyase (PAL) under salinity stress Hernández-Fuentes et al, 2017;. Application of Cs hydrogel along with CuNPs improved tomato growth and quality compared to Cs hydrogel or CuNPs treatment (Juárez-Maldonado et al, 2016). Cs-PVA and CuNPs absorbed on Cs-PVA showed different biochemical response under salinity stress.…”

“…The application of titania (TiO 2 ) NPs improved the activity of catalase (CAT), glutathione peroxidase (GPOX), and superoxide dismutase (SOD) and reduced oxidative stress in Duckweed ( Lemna minor ) plants ( Song et al, 2012 ). Several beneficial and stress countering effects of NPs application in various crops have been reported, such as improved growth in Solanum lycopersicum L. ( Shankramma et al, 2016 ) and Allium cepa L. ( Anandaraj and Natarajan, 2017 ); S. lycopersicum L. ( Juárez-Maldonado et al, 2016 ; Hernández-Hernández et al, 2018 ), Oryza sativa ( Ahmed et al, 2021c ), Capsicum annuum ( Pinedo-Guerrero et al, 2017 ; Mozafari et al, 2018 ). Therefore, it can be concluded that the stress ameliorative potential of NPs can be exploited to combat various negative effects caused by abiotic stresses in crop plants.…”

Abiotic stresses, such as heavy metals (HMs), drought, salinity and water logging, are the foremost limiting factors that adversely affect the plant growth and crop productivity worldwide. The plants respond to such stresses by activating a series of intricate mechanisms that subsequently alter the morpho-physiological and biochemical processes. Over the past few decades, abiotic stresses in plants have been managed through marker-assisted breeding, conventional breeding, and genetic engineering approaches. With technological advancement, efficient strategies are required to cope with the harmful effects of abiotic environmental constraints to develop sustainable agriculture systems of crop production. Recently, nanotechnology has emerged as an attractive area of study with potential applications in the agricultural science, including mitigating the impacts of climate change, increasing nutrient utilization efficiency and abiotic stress management. Nanoparticles (NPs), as nanofertilizers, have gained significant attention due to their high surface area to volume ratio, eco-friendly nature, low cost, unique physicochemical properties, and improved plant productivity. Several studies have revealed the potential role of NPs in abiotic stress management. This review aims to emphasize the role of NPs in managing abiotic stresses and growth promotion to develop a cost-effective and environment friendly strategy for the future agricultural sustainability.

“…It is known that copper-based NPs can have a positive effect on plant development both during traditional seed germination [ 16 ] and in tissue culture [ 17 , 18 ]. NPs are used as elicitors for the synthesis of bioactive compounds, since they can affect the secondary metabolism in plants, as well as in culture systems [ 19 ].…”

Recently, metal oxide nanoparticles (NPs) have attracted attention as promising components for the protection and stimulation of plant microclones in tissue culture in vitro. However, the effect of NPs on the genetic mechanisms underlying plant adaptive responses remains poorly understood. We studied the effect of column-shaped CuO NPs 50 nm in diameter and 70–100 nm in length at a concentration of 0.1–10 mg/L on the development of phytopathogenic fungi Alternaria alternata, Fusarium oxysporum, and Fusarium avenaceum in culture, as well as on the infection of downy birch micro-clones with phytopathogens and the level of genes expression associated with the formation of plant responses to stress induced by microorganisms. CuO NPs effectively suppressed the development of colonies of phytopathogenic fungi A. alternata and F. avenaceum (up to 68.42% inhibition at 10 mg/L CuO NPs) but not the development of a colony of F. oxysporum. Exposure to the NPs caused multidirectional responses at the level of plant genes transcription: 5 mg/L CuO NPs significantly increased the expression level of the LEA8 and MYB46 genes and decreased the expression of DREB2 and PAL. Infection with A. alternata significantly increased the level of MYB46, LEA8, PAL, PR-1, and PR-10 transcripts in birch micro-clones; however, upon exposure to a medium with NPs and simultaneous exposure to a phytopathogen, the expression of the MYB46, PR-1, and PR-10 genes decreased by 5.4 times, which is associated with a decrease in the pathogenic load caused by the effect of NPs and the simultaneous stimulation of clones in vitro. The results obtained can be used in the development of preparations based on copper oxide NPs for disinfection and stimulation of plant phytoimmunity during clonal micropropagation of tree crops.
