“…For instance, the presence of inorganic substances (PO 4 3− , S 2− ) in the sap can lead to the transformation of iron NPs. Similarly, phloem sap containing organic acids inhibits the disintegration of Ag NPs (de la Rosa et al 2021 ). NP uptake and transport are also species dependent.…”

Drought stress remains one of the most detrimental environmental constraints that hampers plant growth and development resulting in reduced yield and leading to economic losses. Studies have highlighted the beneficial role of carbon-based nanomaterials (NMs) such as multiwalled carbon nanotubes (MWNTs), single-walled carbon nanotubes (SWNTs), graphene, fullerene, and metal-based nanoparticles (NPs) (Ag, Au, Cu, Fe2O3, TiO2, and ZnO) in plants under unfavorable conditions such as drought. NPs help plants cope with drought by improving plant growth indices and enhancing biomass. It improves water and nutrient uptake and utilization. It helps retain water by altering the cell walls and regulating stomatal closure. The photosynthetic parameters in NP-treated plants reportedly improved with the increase in pigment content and rate of photosynthesis. Due to NP exposure, the activation of enzymatic and nonenzymatic antioxidants has reportedly improved. These antioxidants play a significant role in the defense system against stress. Studies have reported the accumulation of osmolytes and secondary metabolites. Osmolytes scavenge reactive oxygen species, which can cause oxidative stress in plants. Secondary metabolites are involved in the water retention process, thus improving plant coping strategies with stress. The deleterious effects of drought stress are alleviated by reducing malondialdehyde resulting from lipid peroxidation. Reactive oxygen species accumulation is also controlled with NP treatment. Furthermore, NPs have been reported to regulate the expression of drought-responsive genes and the biosynthesis of phytohormones such as abscisic acid, auxin, gibberellin, and cytokinin, which help plants defend against drought stress. This study reviewed 72 journal articles from 192 Google Scholar, ScienceDirect, and PubMed papers. In this review, we have discussed the impact of NP treatment on morphological, physio-biochemical, and molecular responses in monocot and dicot plants under drought conditions with an emphasis on NP uptake, transportation, and localization.

Due to their unique characteristics, nanoparticles are increasingly used in agricultural production through foliage spraying and soil application. The use of nanoparticles can improve the efficiency of agricultural chemicals and reduce the pollution caused by the use of agricultural chemicals. However, introducing nanoparticles into agricultural production may pose risks to the environment, food and even human health. Therefore, it is crucial to pay attention to the absorption migration, and transformation in crops, and to the interaction with higher plants and plant toxicity of nanoparticles in agriculture. Research shows that nanoparticles can be absorbed by plants and have an impact on plant physiological activities, but the absorption and transport mechanism of nanoparticles is still unclear. This paper summarizes the research progress of the absorption and transportation of nanoparticles in plants, especially the effect of size, surface charge and chemical composition of nanoparticle on the absorption and transportation in leaf and root through different ways. This paper also reviews the impact of nanoparticles on plant physiological activity. The content of the paper is helpful to guide the rational application of nanoparticles in agricultural production and ensure the sustainability of nanoparticles in agricultural production.

“…For plants to be protected from insect pests, the active ingredient must be present in a threshold concentration, and one such method is nanotechnology, where the key component of the chemical formulation has been enclosed within nanomaterials (de la Rosa et al, 2021). In contrast to traditional pesticides, which are highly soluble and can damage plants around the pointed species, resulting in the target species developing a resistance to the pesticide, encapsulated pesticides last for long periods, releasing the necessary quantity of active constituent at the target site (de la Rosa et al, 2021). It has been found that inorganic nanoparticles (ZnO, Cu, SiO 2 , TiO 2 , CaO, MgO, MnO, and Ag) are effective against microbes in plants ( Tang and Zheng, 2018).…”

EVIEWING Agri-nanotechnology from the perspective of nanoparticles and crops will help us better understand the interactions between nanoparticles and crops, such as uptake, mobilization, and accumulation. In recent years, a great deal has been accomplished in nanotechnology in biomedical sciences, revolutionizing therapeutic and diagnostic techniques. Despite that, additional research is introducing the NPs on plant development and agroecosystems for smart nontechnological approaches for crop enhancement. Here, we have swiftly introduced NPs used in plant science and described the methods of application uptake, mobilization, and biological effects of NPs on crops. Intending to invigorate plant safety or promote plant progression and development that affected crop production. This review examines the essential present applications of NPs in agriculture while also exploring the potential application of NPs in a regulatory manner, which could open novel and harmless possibilities for the intelligent delivery of biomolecules and for novel tactics in crop nutrient management, crop genetic engineering, and battling against abiotic stresses in climate change era.
