“…Bean plant ( Phaseolus vulgaris L.) belonging to the salt-sensitive classification has shown improved seed germination when treated with 0.1%, 0.2%, and 0.3% nanochitosan at 100 Mm salt concentration [ 49 ]. Nitric oxide (NO) releasing chitosan nanoparticles were shown to be more effective than free NO donors in combating salt stress in maize [ 51 ] ( Figure 3 ). Chitosan delivered NO has enhanced the leaf S-nitrosothiols, photosystem II activity, and chlorophyll levels in treated plants by increasing the bioavailability of NO [ 51 ].…”

Chitosan has emerged as a biodegradable, nontoxic polymer with multiple beneficial applications in the agricultural and biomedical sectors. As nanotechnology has evolved as a promising field, researchers have incorporated chitosan-based nanomaterials in a variety of products to enhance their efficacy and biocompatibility. Moreover, due to its inherent antimicrobial and chelating properties, and the availability of modifiable functional groups, chitosan nanoparticles were also directly used in a variety of applications. In this review, the use of chitosan-based nanomaterials in agricultural and biomedical fields related to the management of abiotic stress in plants, water availability for crops, controlling foodborne pathogens, and cancer photothermal therapy is discussed, with some insights into the possible mechanisms of action. Additionally, the toxicity arising from the accumulation of these nanomaterials in biological systems and future research avenues that had gained limited attention from the scientific community are discussed here. Overall, chitosan-based nanomaterials show promising characteristics for sustainable agricultural practices and effective healthcare in an eco-friendly manner.

“…For example, atrazine-containing polymeric nanocapsules showed a 10-fold higher post-emergence herbicidal activity towards mustard plants, compared to free atrazine (Oliveira et al, 2015). In a recent study, Oliveira, Gomes, Pelegrino, & Seabra (2016) demonstrated that nitric oxide-releasing CS nanoparticles were more effective than the free nitric oxide donor in protecting maize plants under salt stress. This enhanced bioactivity of nitric oxide was also related to the sustained release of the plant growth regulator by the nanoparticles (Oliveira, Gomes, Pelegrino, & Seabra, 2016).…”

The use of nanocarriers for plant growth regulators can therefore enable the use of lower dosages of these molecules, reducing both costs and the risk of phytotoxicity.…”

“…Growth regulators, whether from synthetic or natural origins, are employed in various ways to increase productivity and profitability (E1-Otmani, Coggins Jr., Agustí, & Lovatt, 2000). Microparticulate release systems have been used for brassinosteroid hormones (Quiñones, García, Curiel, & Covas, 2010) and naphthalene acetic acid (Tao, Pang, Chen, Ren, & Hu, 2012), and chitosan nanoparticles have been used for the controlled release of nitric oxide (Oliveira, Gomes, Pelegrino, & Seabra, 2016). Studies have shown that carbon nanotubes induce effects similar to those of plant hormones; for example, Khodakovskaya et al (2013) showed that the use of multi-walled carbon nanotubes could increase twice the flowers and fruits of tomato.…”

The growth regulator gibberellic acid (GA) has several uses in the field, improving germination, plant development, productivity, and the quality of food. This work describes the development of a nanocarrier system for GA, based on the poly(γ-glutamic acid) (γ-PGA) and chitosan (CS) polymers, Nanoparticles without GA (nano-γPGA/CS-GA) showed colloidal characteristics, with an average size of 117±9nm, PDI of 0.43±0.07, and zeta potential of -29±0.5mV. The encapsulated nanoparticles (nano-γPGA/CS-GA) presented an average size of 134±9nm, PDI of 0.35±0.05, zeta potential of 27.9±0.5mV, and 61% encapsulation. The images of nanoparticles observed by Transmission and scanning electron microscopy (TEM and SEM) showed a spherical shape of the nanoparticles. The system showed sustained release, with 58% release after 48h. Evaluation of thermal properties using DSC and TGA analyses indicated that there was an interaction between the CS and γ-PGA polymers. In tests using Phaseolus vulgaris seeds, nano-γPGA/CS-GA showed high biological activity, enhancing the rate of germination in the first day (50-70%) when compared with free GA (10-16%). Encapsulated GA was also more efficient than the free hormone in the increase of leaf area and the induction of root development (including the formation of lateral roots). These effects were not observed when seeds were treated with nano-γPGA/CS without GA. The results demonstrated the considerable potential of nano-γPGA/CS-GA for use in agriculture.

Nitric oxide (NO) is an integral part of cell signaling mechanisms in animals and plants. In plants, its enzymatic generation is still controversial. Evidence points to nitrate reductase being important, but the presence of a nitric oxide synthase-like enzyme is still contested. Regardless, NO has been shown to mediate many developmental stages in plants, and to be involved in a range of physiological responses, from stress management to stomatal aperture closure. Downstream from its generation are alterations of the actions of many cell signaling components, with post-translational modifications of proteins often being key. Here, a collection of papers embraces the differing aspects of NO metabolism in plants.
