Special Issue Information

Dear Colleagues,

In recent years, nanotechnology has attracted a great deal of attention from researchers due to its wide range of applications in various sectors, including agriculture. Agriculture is the backbone society and the main source of more than 50% of the raw materials supplied to many industrial sectors. It is, therefore, important that farmers are encouraged and supported with new technologies to sustainably grow crops of better quality and that are more cost effective and ecofriendly, with higher yield and significant returns. Currently, thousands of tons of metal and metal oxide nanoparticles are produced and utilized in medicinal, food and agricultural products. These metal and metal oxide nanoparticles are widely used in the agricultural sector due to their distinctive properties such as high surface area, tunable size and shape, physicochemical properties and particle morphology. It is generally accepted that the reaction techniques and compounds used to produce metal and metal oxide nanoparticles are environmentally friendly. Hence, green synthesis has been proposed as an alternative, eco-friendly method to reduce the use of toxic, harsh and hazardous chemicals. The organic compounds, microbes, plants and plant-derived materials are the preferred choices as reducing and capping agents for the synthesis of metal and metal oxide nanoparticles. There have been advances in the development of nano-based materials such as nanoparticles and nanoformulations that can be used as fertilizers, herbicides, pesticides, sensors, quality simulants, antimicrobials against plant pathogens and other applications in agricultural sectors. Metal and metal oxide nanoparticles are influencing plant metabolisms, reducing loss of nutrients, suppressing diseases and thereby enhancing the yields, plant growth and production. This Special Issue aims to attract contributions on all aspects of biosynthesis, characterization and applications of different metal and metal oxide nanomaterials on plant research in agricultural sectors including antimicrobial activities of plant pathogens and toxicity of nanomaterials. Original research articles and reviews that make substantial advances within this field are invited to this editorial project.

Drought stress is known as a major yield-limiting factor in crop production that threatens food security worldwide. Arbuscular mycorrhizal fungi (AMF) and titanium dioxide (TiO2) have shown to alleviate the effects of drought stress on plants, but information regarding their co-addition to minimize the effects of drought stress on plants is scant. Here, a two-year field experiment was conducted in 2019 and 2020 to evaluate the influence of different irrigation regimes and fertilizer sources on the EO quantity and quality of sage (Salvia officinalis L.). The experiment was laid out as a split plot arranged in a randomized complete block design with three replicates. The irrigation treatments were 25, 50, and 75% maximum allowable depletion (MAD) percentage of the soil available water as non-stress (MAD25), moderate (MAD50), and severe (MAD75) water stress, respectively. Subplots were four fertilizer sources including no-fertilizer control, TiO2 nanoparticles (100 mg L−1), AMF inoculation, and co-addition of TiO2 and AMF (TiO2 + AMF). Moderate and severe drought stress decreased sage dry matter yield (DMY) by 30 and 65%, respectively. In contrast, application of TiO2 + AMF increased DMY and water use efficiency (WUE) by 35 and 35%, respectively, compared to the unfertilized treatment. The highest EO content (1.483%), yield (2.52 g m−2), and cis-thujone (35.84%, main EO constituent of sage) was obtained in MAD50 fertilized with TiO2 + AMF. In addition, the net income index increased by 44, 47, and 76% with application of TiO2 nanoparticles, AMF, and co-addition of TiO2 + AMF, respectively. Overall, the integrative application of the biofertilizer and nanoparticles (TiO2 + AMF) can be recommended as a sustainable strategy for increasing net income and improving EO productivity and quality of sage plants in drought stress conditions. Future policy discussions should focus on incentivizing growers for replacing synthetic fertilizers with proven nano and biofertilizers to reduce environmental footprints and enhance the sustainability of sage production, especially in drought conditions.

Nowadays, green synthesized nanoparticles (NPs) are extensively investigated to explore their biological potential. They are being explored to treat different infectious and cancerous diseases. Therefore, the current study was designed to evaluate the cytotoxic and genotoxic effects of biosynthesized silver nanoparticles (AgNPs) from the medicinal plant Moringa oleifera on breast cancer (MCF-7) and HUVEC (human umbilical vein endothelial cells) cell lines. M. oleifera-mediated AgNPs were synthesized from the M. oleifera extract (MOE) and then characterized through the use of a scanning electron microscope (SEM), X-ray diffraction (XRD) and UV–vis spectrophotometer. Biosynthesized AgNPs and MOE were employed on MCF-7 and HUVEC cell lines to evaluate their cytotoxic and genotoxic effects. More cytotoxic effects were observed by AgNPs and MOE on MCF-7 cell lines. The IC50 for biosynthesized AgNPs was found to be 5 μg/mL. DNA damage was also observed by the MOE and AgNPs on MCF-7 cell lines. However, non-significant DNA damage was observed by MOE and AgNPs on HUVEC cell lines. The findings of the current study revealed the cytotoxic and genotoxic effects of biosynthesized AgNPs on MCF-7 cell lines. However, these AgNPs were considered safe for normal HUVEC cell lines.

The current study demonstrated the capability of using maize silk as a green, simple, clean, safe, and cost-effective platform for the biosynthesis of cerium oxide (CeO2NPs). Several spectroscopic and microscopic analyses were employed to characterize the resulted biogenic nanoceria. When the concentration of the CeO2NPs was elevated from 25 to 100 ug mL−1, the CeO2NPs exhibited strong scavenging potential ranging from 60.21 to 75.11% and 56 to 77% for 1,1-diphenyl-2- picrylhydrazyl (DPPH•) and 2-2′-azino-bis(3-ethyl benzothiazoline-6-sulphonic acid) (ABTS) tests, respectively. The quantitative determination of ferulic, sinapic, and p-coumaric acids was carried out using an eco-friendly, cost-effective, and optimized ultrasensitive nanoceria enhanced sequential injection-chemiluminescence (SIA-CL) system. The highest amount was presented by the ferulic acid (1636 ± 2.61 ug/gdw), followed by p-coumaric acid (206 ± 1.12 ug/gdw) and sinapic acid (123 ± 2.15 ug/gdw). The intrinsic capabilities of the biogenic CeO2NPs in enhancing the developed system reveal its potential role in detecting phenolic compounds with great sensitivity. Full article
