“…Drought is among the most damaging climatic hazards to agriculture, leading to significant farm yield and economic loss. , In addition, with the recent expansion of the global population and the rapidly changing climate, concern over the impact of drought on food security is escalating. , In fact, projections estimate that agricultural output will have to increase by 60–70% by 2050 to feed the global population. Therefore, developing safe and effective strategies to enhance drought tolerance of crops is warranted and can be an important approach to maintain food production under increasingly marginal growth conditions …”

Drought is among the most damaging climatic hazards affecting crop productivity and nutritional quality. Here, we investigated the influence of Cu-based materials at mitigating drought stress in soybeans (Glycine max) during the reproductive stage in order to elucidate effects on productivity. Commercial copper oxide (CuO) nanoparticles (NPs), in-house synthesized copper sulfide (CuS) NPs, and copper sulfate (CuSO4) were foliar applied at 10 mg Cu/L daily for 1 week to soybean that were exposed to water deficit at the onset of flowering, and plants were harvested 5 days after exposure. Drought inhibited flower production by 27% compared to the nondrought treatment. Notably, both CuS NPs and ionic Cu mitigated the drought-induced inhibition of flower production, showing 41.7 and 33.3% improvement. CuS NPs exhibited the most positive impact on restoring shoot biomass, pod biomass, and shoot moisture content, increasing values by 53, 96, and 10%, respectively, compared to the drought control plants. The Cu-based materials maintained photosynthetic parameters under drought conditions and modulated oxidative damage by enhancing reactive oxygen species-scavenging enzyme activities. Furthermore, CuO NP treatment increased shoot and pod Cu levels by 624 and 54%, respectively, compared to the drought control plants. Taken together, these findings suggest that Cu-based materials modulate plant protective mechanisms against drought stress during the flowering stage, offering a potentially important nanoenabled strategy to promote biofortified climate resilient crops.

Nano-priming is an emerging application of nanotechnology in agriculture intending to increase crop yield and nutritional quality, while reducing fertilizer applications. This study aimed to investigate the effects of seed priming with citrate-coated CoFe2O4 nanoparticles (NPs) suspensions (10, 20, and 40 mg NPs L− 1) on the life cycle of the Phaseolus vulgaris L. OTI cultivar and evaluate the technology costs. The effect of nano-priming was assessed in the germination, flowering, and harvest stages. Unprimed and hydro-primed seeds were negative and positive controls, respectively. Nano-priming with CoFe2O4 NPs had no effect neither on the germination nor on plant nutrition (in the flowering stage) of OTI beans compared to unprimed and hydro-primed seeds. In contrast, nitrogenase activity (343.3 ± 1.1 µmol h− 1 plant− 1 of C2H4 ) was detected in the plants from the 40 mg kg− 1 nano-primed seeds. The K concentration of progeny seeds from nano-priming with 10, 20, and 40 mg NPs L− 1 increased significantly by 3%, 16%, and 13% compared to the control seeds. The Zn concentration in the seeds from nano-priming with 10 mg NPs L− 1 was 27% higher than in the control and 28% higher than in the hydro-primed seeds. When nano-priming with 40 mg NPs L− 1, the Zn concentration was 5% and 6% higher than the control and hydro-primed seeds. The calculated cost of nano-priming seeds per ha ranged from 121 to 143 USD. In this regard, nano-priming of bean seeds with citrate-coated CoFe2O4 NPs could be a low-cost approach to achieve nutritional security and agricultural sustainability.

The intensive applications of nanomaterials in the agroecosystem led to the creation of several environmental problems. More efforts are needed to discover new insights in the nanomaterial–microbe–plant nexus. This relationship has several dimensions, which may include the transport of nanomaterials to different plant organs, the nanotoxicity to soil microbes and plants, and different possible regulations. This review focuses on the challenges and prospects of the nanomaterial–microbe–plant nexus under agroecosystem conditions. The previous nano-forms were selected in this study because of the rare, published articles on such nanomaterials. Under the study’s nexus, more insights on the carbon nanodot–microbe–plant nexus were discussed along with the role of the new frontier in nano-tellurium–microbe nexus. Transport of nanomaterials to different plant organs under possible applications, and translocation of these nanoparticles besides their expected nanotoxicity to soil microbes will be also reported in the current study. Nanotoxicity to soil microbes and plants was investigated by taking account of morpho-physiological, molecular, and biochemical concerns. This study highlights the regulations of nanotoxicity with a focus on risk and challenges at the ecological level and their risks to human health, along with the scientific and organizational levels. This study opens many windows in such studies nexus which are needed in the near future.
