“…Due to the nature of the molecules and the sensitivity to environmental factors [ 15 ], the treatment of plants with NO donors has limitations, mainly aimed at using the technique in less favorable environments, such as the agroecosystem. As an alternative, the nanoencapsulation of NO donors can make the exogenous application of NO an effective tool in protecting plants against different types of stress [ 14 , 16 , 18 , 19 , 20 ], enabling its use in agriculture.…”

“…To reduce the limitations of the application of NO donors, chitosan polymeric nanoparticles have been developed as carrier systems for these molecules [ 15 ], aiming at protecting plants against different stresses, such as salinity [ 16 , 17 ]; photoinhibition [ 18 ], and drought [ 14 , 19 , 20 ]. Furthermore, NO-releasing chitosan nanoparticles have been suggested to be the most suitable candidates to alleviate the toxicity caused by metal in plants, owing to their unique properties, managing to release NO efficiently and with a prolonged duration [ 21 ].…”

The nanoencapsulation of nitric oxide (NO) donors is an attractive technique to protect these molecules from rapid degradation, expanding, and enabling their use in agriculture. Here, we evaluated the effect of the soil application of chitosan nanoparticles containing S-nitroso-MSA (a S-nitrosothiol) on the protection of soybeans (Glycine max cv. BRS 257) against copper (Cu) stress. Soybeans were grown in a greenhouse in soil supplemented with 164 and 244 mg kg−1 Cu and treated with a free or nanoencapsulated NO donor at 1 mM, as well as with nanoparticles without NO. There were also soybean plants treated with distilled water and maintained in soil without Cu addition (control), and with Cu addition (water). The exogenous application of the nanoencapsulated and free S-nitroso-MSA improved the growth and promoted the maintenance of the photosynthetic activity in Cu-stressed plants. However, only the nanoencapsulated S-nitroso-MSA increased the bioavailability of NO in the roots, providing a more significant induction of the antioxidant activity, the attenuation of oxidative damage, and a greater capacity to mitigate the root nutritional imbalance triggered by Cu stress. The results suggest that the nanoencapsulation of the NO donors enables a more efficient delivery of NO for the protection of soybean plants under Cu stress.

“…The few pioneer studies of nano NO donors in plants have explored only chitosan nanoparticles, which is a cost‐efficient and eco‐friendly biopolymer (Oliveira et al ., 2016; Lopes‐Oliveira et al ., 2019; do Carmo et al ., 2021; Silveira et al ., 2021a). However, there are many other biodegradable, biocompatible polymers obtained from renewable sources to be used, such as lignin, alginate, cellulose and zein (Darder et al ., 2020; Urzedo et al ., 2020; Low et al ., 2021).…”

Nitric oxide‐releasing nanomaterials: from basic research to potential biotechnological applications in agriculture

Nitric oxide (NO) is a multifunctional gaseous signal that modulates the growth, development and stress tolerance of higher plants. NO donors have been used to boost plant endogenous NO levels and to activate NO-related responses, but this strategy is often hindered by the relative instability of donors. Alternatively, nanoscience offers a new, promising way to enhance NO delivery to plants, as NOreleasing nanomaterials (e.g. S-nitrosothiol-containing chitosan nanoparticles) have many beneficial physicochemical and biochemical properties compared to non-encapsulated NO donors. Nano NO donors are effective in increasing tissue NO levels and enhancing NO effects both in animal and human systems. The authors believe, and would like to emphasize, that new trends and technologies are essential for advancing plant NO research and nanotechnology may represent a breakthrough in traditional agriculture and environmental science. Herein, we aim to draw the attention of the scientific community to the potential of NO-releasing nanomaterials in both basic and applied plant research as alternatives to conventional NO donors, providing a brief overview of the current knowledge and identifying future research directions. We also express our opinion about the challenges for the application of nano NO donors, such as the environmental footprint and stakeholder's acceptance of these materials.

“…Having in mind all the issues just discussed, it seems unlikely that NO donors can mirror the specific acclimation roles of endogenous NO during nutrient deficiencies, and interactive no obvious effects on NUE for different elements may be expected. Nevertheless, the possibility to use NO-releasing nanoparticles should be not excluded as they may deliver NO in a more controlled way (as compared to free forms), promoting growth under particular stress conditions (Silveira et al, 2021 ). Similar considerations may apply for specific transgenic plants.…”
