“…NO protects cells from oxidative damage by increasing the activity of antioxidant enzymes. For example, the application of a NO donor to NaCl-treated plants increased the activity of SOD, CAT, and APX [ 21 , 55 , 59 , 64 ]. Application of a NO donor to salt-treated A. corniculatum also enhanced the activity of GPX, which catalyzes the detoxification of peroxides and hydroperoxides [ 62 ].…”

The gas nitric oxide (NO) plays an important role in several biological processes in plants, including growth, development, and biotic/abiotic stress responses. Salinity has received increasing attention from scientists as an abiotic stressor that can seriously harm plant growth and crop yields. Under saline conditions, plants produce NO, which can alleviate salt-induced damage. Here, we summarize NO synthesis during salt stress and describe how NO is involved in alleviating salt stress effects through different strategies, including interactions with various other signaling molecules and plant hormones. Finally, future directions for research on the role of NO in plant salt tolerance are discussed. This summary will serve as a reference for researchers studying NO in plants.

“…For example, wheat plants enhanced SOD, GR, APX and glutathione peroxidase (GPX) under NaCl stress (100 mM) for 30 days [99]. Barley plants had high CAT activities, SOD, APX while lower MDA content under salinity stress after application of Se-nanoparticles [75,101]. However, Habibi and Aleyasin [75] reported that excessive salts stress reduced the activity of SOD but increased the activity of malondialdehyde (MDA) in barley plants.…”

The productivity of cereal crops under salt stress limits sustainable food production and food security. Barley followed by sorghum better adapts to salinity stress, while wheat and maize are moderately adapted. However, rice is a salt-sensitive crop, and its growth and grain yield are significantly impacted by salinity stress. High soil salinity can reduce water uptake, create osmotic stress in plants and, consequently, oxidative stress. Crops have evolved different tolerance mechanisms, particularly cereals, to mitigate the stressful conditions, i.e., effluxing excessive sodium (Na+) or compartmentalizing Na+ to vacuoles. Likewise, plants activate an antioxidant defense system to detoxify apoplastic cell wall acidification and reactive oxygen species (ROS). Understanding the response of field crops to salinity stress, including their resistance mechanisms, can help breed adapted varieties with high productivity under unfavourable environmental factors. In contrast, the primary stages of seed germination are more critical to osmotic stress than the vegetative stages. However, salinity stress at the reproductive stage can also decrease crop productivity. Biotechnology approaches are being used to accelerate the development of salt-adapted crops. In addition, hormones and osmolytes application can mitigate the toxicity impact of salts in cereal crops. Therefore, we review the salinity on cereal crops physiology and production, the management strategies to cope with the harmful negative effect on cereal crops physiology and production of salt stress.

“…Moreover, TiO2 NPs in step with se may also act as nano-nutrient fertilizer to improve biomass production by invigorating plant metabolic activities (Hojjat 2019). In expansion, NPs can sequester nutrient components on their surface and serve as a nutrient stock to the plants (Karami and Sepehri 2018). TiO2 NPs may actuate oxidation-reduction reactions by the superoxide ion radical amid germination, coming about in rummaging free radicals within the sprouting seeds and oxygen produced in such preparation might moreover be expended in the respiration, which would advance enhance germination (Khot et al 2012).…”

In spite of the fact that the capability of Tio2 NPs in improving saltiness opposition has been accounted for in a few plant groups (Karami and Sepehri 2018;Lin and Xing 2007), its role in the mitigation of saltiness sway and related components is as yet obscure.

In the current examination, we assessed the impacts of titanium dioxide nanoparticles (TiO2 NPs) for ameliorating salinity in Grass pea (Lathyrus sativus L.), a useful legumes crop. Experimental salinity was controlled in terms of dSm-1 at levels of 0 (control), 4, 8 and 12 dSm-1 , have been researched in a factorial experiment based on randomized complete block design with three replications. The impacts of four distinctive TiO2 NPs concentrations (0, 20, 40 and 60 mg L-1) were contrasted with deference with plant development and stress reactions. Germination and seedling emergence percentage was fundamentally affected by 12 dSm-1 of NaCl. Presentation to NaCl stress essentially decreased length of grass pea seedling organs (root and shoot) comparatively, the substance of proline expanded for the most part in the roots from moderate saltiness conditions. In any case, foliar of nano-TiO2 conquered pernicious impacts of salt pressure and improved the vast majority of these parameters. The best outcomes were found at 20 mg L-1 nano-TiO2. Generally, utilization of Tio2 was useful in expanding saltiness resistance in Grass pea seedlings and their application may incite a reasonable strategy to ensure plants against sodium harmfulness.
