“…These NPs, when they reach the soil, can interact with the microorganisms that inhabit it. However, the effects are not clear, although it has been mentioned that in general nanomaterials (NMs) have a lower toxicity than their ionic forms, with the exception of those which are based on Ag [17].…”

Early blight is a disease that greatly affects Solanaceae, mainly damaging tomato plants, and causing significant economic losses. Although there are methods of biological control, these are very expensive and often their mode of action is slow. Due to this, there is a need to use new techniques that allow a more efficient control of pathogens. Nanotechnology is a new alternative to solve these problems, allowing the creation of new tools for the treatment of diseases in plants, as well as the control of pathogens. The aim of the present investigation was to evaluate the foliar application of selenium and copper in the form of nanoparticles in a tomato crop infested by Alternaria solani. The severity of Alternaria solani, agronomic variables of the tomato crop, and the changes in the enzymatic and non-enzymatic antioxidant compounds were evaluated. The joint application of Se and Cu nanoparticles decreases the severity of this pathogen in tomato plants. Moreover, high doses generated an induction of the activity of the enzymes superoxide dismutase, ascorbate peroxidase, glutathione peroxidase (GPX) and phenylalanine ammonia lyase in the leaves, and the enzyme GPX in the fruit. Regarding non-enzymatic compounds in the leaves, chlorophyll a, b, and totals were increased, whereas vitamin C, glutathione, phenols, and flavonoids were increased in fruits. The application of nanoparticles generated beneficial effects by increasing the enzymatic and non-enzymatic compounds and decreasing the severity of Alternaria solani in tomato plants.

“…25 The Gram-positive bacterium Bacillus subtilis SB491 (B. subtilis) is commonly found in soil and on plant undergrowth and is widely used for nanotoxicity studies. 26 While plenty of previous work has revealed the role of ROS and metal ions in nano-metal/metal oxide toxicity to microorganisms (Table S1 †), the goal of this study is to focus on DNA damage, a potentially universal toxicity mechanism, and reveal relevant molecular details of nano-bacteria interactions that can be potentially extrapolated to a wide range of organisms.…”

“…[31] These reactions may take place at the cell membrane, as well as in the cell cytoplasm or even outside of the cell. Microorganisms release large amounts of enzymes into soil, [62,63] which mediate and catalyze many biogeochemical reactions, such as the decomposition of plant/animal/microbial debris and nutrient (e.g., N, C, P, S) cycling, thereby facilitating the release of inorganic nutrients from minerals for plant growth. These enzymes, including oxidases, reductases, hydrolases, and lyases, [64] may also catalyze the transformation of ENMs.…”

Engineered nanomaterials (ENMs) have huge potential for improving use efficiency of agrochemicals, crop production, and soil health; however, the behavior and fate of ENMs and the potential for negative long‐term impacts to agroecosystems remain largely unknown. In particular, there is a lack of clear understanding of the transformation of ENMs in both soil and plant compartments. The transformation can be physical, chemical, and/or biological, and may occur in soil, at the plant interface, and/or inside the plant. Due to these highly dynamic processes, ENMs may acquire new properties distinct from their original profile; as such, the behavior, fate, and biological effects may also differ significantly. Several essential questions in terms of ENMs transformation are discussed, including the drivers and locations of ENM transformation in the soil–plant system and the effects of ENM transformation on analyte uptake, translocation, and toxicity. The main knowledge gaps in this area are highlighted and future research needs are outlined so as to ensure sustainable nanoenabled agricultural applications.
