“…By increasing the effectiveness of redox processes and/or activating H 2 O 2 -metabolizing enzymes, Fe 3 O 4 NPs may be used to reduce or eliminate H 2 O 2 production. Fe 3 O 4 NPs-treated Oryza sativa plants experienced a rise in their biomass, antioxidant enzyme activities, photosynthetic efficiency, and nutrient uptake during drought stress [ 12 ]. These findings suggest that increasing the amount of iron applied to plants in the form of nanoparticles could be beneficial to their growth and physiology.…”

“…MONPs have been utilized to protect plants from oxidative stress by increasing the activity of antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), and peroxidase (POX) [ 12 ]. MONPs have the potential to reduce the detrimental impact of drought on plant physiological functions by lowering malondialdehyde (MDA) and hydrogen peroxide (H 2 O 2 ) contents and maintaining photosynthetic systems [ 12 , 13 ]. Under drought stress, they play a role in signaling pathways, defense, metabolism, and regulatory activities.…”

Metal oxide nanoparticles (MONPs) are regarded as critical tools for overcoming ongoing and prospective crop productivity challenges. MONPs with distinct physiochemical characteristics boost crop production and resistance to abiotic stresses such as drought. They have recently been used to improve plant growth, physiology, and yield of a variety of crops grown in drought-stressed settings. Additionally, they mitigate drought-induced reactive oxygen species (ROS) through the aggregation of osmolytes, which results in enhanced osmotic adaptation and crop water balance. These roles of MONPs are based on their physicochemical and biological features, foliar application method, and the applied MONPs concentrations. In this review, we focused on three important metal oxide nanoparticles that are widely used in agriculture: titanium dioxide (TiO2), zinc oxide (ZnO), and iron oxide (Fe3O4). The impacts of various MONPs forms, features, and dosages on plant growth and development under drought stress are summarized and discussed. Overall, this review will contribute to our present understanding of MONPs’ effects on plants in alleviating drought stress in crop plants.

“…Nanozero valent iron was found to be good enough in restricting Cd uptake by inhibiting the expression of various iron transporters in rice exposed to moderate (10 µM) Cd toxicity (110). In a recent study, Cd uptake was withheld due to the suppression of three Cd transporter genes OsLCT1, OsHMA2 and OsHMA3 in Cd stressed rice co treated with different concentration of biofabricated iron NP (111).…”

“…Photosynthetic efficiency is highly susceptible to heavy metal induced ROS production. Recent study (111) has established the antioxidant capacity of biofabricated (biogenic, eco friendly, less toxic) iron NP applied against Cd treated rice plant. Maximum increase in antioxidant enzymes (CAT-32%, POD-48%, SOD-32%) with simultaneous decrease in ROS (H2O2-54%) was recorded in Cd and drought stressed rice seedling with concurrent use of IONP (100 mg/kg soil) and chemically synthesised hydrogel NP.…”

Application of nanoparticles to address various environmental issues; especially heavy metal contaminated soil restoration is of global interest. Indiscriminate usage of phosphate fertilizer and other anthropogenic activities contribute to Cd contamination of soil, resulting in degradation of soil quality and low crop yield. By the virtue of unique physiochemical characteristics, nanoparticles (NPs) are effective enough for heavy metal stress mitigation. This review has focused on Cd uptake, accumulation and toxicity in plants followed by the successful application of different metallic and non metallic NPs for soil Cd decontamination. Positive impact of NPs as plant growth elicitor under Cd stress has been explored here. Various ways of NP application (soil, foliar, hydroponics), uptake, mode of action and effective treatment concentration have been highlighted. We have collected handful information regarding the use of NPs as nanofertilizer and nanopesticides. The negative effects of NPs have not been considered here. More in depth study to be conducted for better illumination on plant - NPs interaction, mobilization mechanism and biological activities. Though this review summarizes few facts among various aspect of NP but can be counted as a supportive documentation for the better use of NPs in environmental protection in future.

“…Although many nanoparticles have been applied as nano-fertilizers or nano-pesticides, which promote crop productivity, but might cause some problems in soil-plant interfaces particularly the over-doses ( Ragab and Saad-Allah, 2020 ). Several studies have depicted applied engineered-NPs as nano-fertilizers (e.g., Guo et al, 2018 ; Farshchi et al, 2021 ; Madzokere et al, 2021 ) to improve crop productivity under many stresses ( Ye et al, 2019 , Landa, 2021 ) like drought ( Sreelakshmi et al, 2020 , Ahmed et al, 2021 , Ali et al, 2021 ), salinity ( Manzoor et al, 2021 , Zulfiqar and Ashraf, 2021 ), pollution of heavy metals ( Noman et al, 2020 , Xin et al, 2020 , Manzoor et al, 2021 ), and biotic stress ( Tauseef et al, 2021a , Tauseef et al, 2021b ). These nanoparticles can enhance cultivated plants under stress through many mechanisms such as improving antioxidant defense system, promoting photosynthesis, increasing water, nutrient and phytohormones ( Zulfiqar and Ashraf, 2021 ).…”

Human health and its improvement are the main target of several studies related to medical, agricultural and industrial sciences. The human health is the primary conclusion of many studies. The improving of human health may include supplying the people with enough and safe nutrients against malnutrition to fight against multiple diseases like COVID-19. Biofortification is a process by which the edible plants can be enriched with essential nutrients for human health against malnutrition. After the great success of biofortification approach in the human struggle against malnutrition, a new biotechnological tool in enriching the crops with essential nutrients in the form of nanoparticles to supplement human diet with balanced diet is called nano-biofortification. Nano biofortification can be achieved by applying the nano particles of essential nutrients (e.g., Cu, Fe, Se and Zn) foliar or their nano-fertilizers in soils or waters. Not all essential nutrients for human nutrition can be biofortified in the nano-form using all edible plants but there are several obstacles prevent this approach. These stumbling blocks are increased due to COVID-19 and its problems including the global trade, global breakdown between countries, and global crisis of food production. The main target of this review was to evaluate the nano-biofortification process and its using against malnutrition as a new approach in the era of COVID-19. This review also opens many questions, which are needed to be answered like is nano-biofortification a promising solution against malnutrition? Is COVID-19 will increase the global crisis of malnutrition? What is the best method of applied nano-nutrients to achieve nano-biofortification? What are the challenges of nano-biofortification during and post of the COVID-19?
