“…The highest leaf number was observed in the T3 (15.75) application, while the lowest leaf number was in the T4 (12.89) application (Table 2). Previous studies have found that SNP applications improve the adverse effects on plants under stress conditions and positively enhanced vegetative growth (Habib et al, 2020;Pradhan et al, 2020;Gougerdchi et al, 2021;Jafari and Shahsavar, 2022;Sardar et al, 2023). Similar studies have also shown that SNP increases leaf number, supporting our findings.…”

“…In another in vitro study, SNP application to Allium hirtifolium increased shoot regeneration in plants under drought stress condition (Ghassemi-Golezani et al, 2018). Similar studies supporting our findings have also demonstrated that SNP application increases shoot length (Ali et al, 2017;Jafari and Shahsavar, 2022). Since SNP has a direct effect on the cell wall, it has been reported that it can cause cell wall loosening, trigger cell expansion and stimulate plant growth (Lamattina et al 2003).…”

Aronia is a berry fruit that has a significant amount of antioxidants. Both sexual and vegetative methods of propagation are available for aronia. Genetic diversity is present in the process of seed propagation. Therefore, clonal propagation techniques such as cuttings, basal shoots, and tissue culture are preferred. Plant tissue culture is a process that offers a high multiplication rate and the ability to produce clean plant material. This study aimed to stimulate the growth of plantlets by introducing several growth-promoting agents into the culture media. Specifically, the effects of a nitric oxide donor SNP (sodium nitroprusside) on the vegetative development of the plants were examined under in vitro conditions. Four distinct concentrations of SNP (0, 100, 200, and 300 µM) were administered to promote vegetative development. The survival rate (%), rooting rate (%), root number (per plantlet), root length (cm), leaf number (per plantlet), shoot length (cm), plant fresh weight (g), and plant dry weight (g) of the plantlets were estimated on the 60th day of growth in the nutrient medium under in vitro conditions. The survival rate was 100% for the applications of SNP at concentrations of 100 µM and 200 µM. The 0 µM treatment had the highest root number, the 100 µM treatment had the longest root, and the 200 µM treatment had the highest values for shoot length. The 0 µM treatment provided the highest values for plant fresh weight, while the 0 and 100 µM applications resulted in the highest plant dry weight values. The study suggested that an increased concentration of SNP causes a toxic effect.

“…While NO’s role as a signaling molecule in enhancing plant tolerance to various abiotic stresses has been well-documented (Gupta and Seth 2020 , 2023 ; Mariyam et al 2023 ; Prajapati et al 2023 ), its specific effect on oxidative and nitrosative processes under drought stress in tomato plants remains less explored. Previous studies have highlighted the importance of NO in drought stress signaling and tolerance in plants, emphasizing its role in activating ROS scavenging enzymes and regulating antioxidative systems (Chavoushi et al 2019 ; Jafari and Shahsavar 2022 ). However, the intricate mechanisms by which NO modulates oxidative and nitrosative processes, particularly in tomato plants under drought stress, have not been thoroughly investigated.…”

Key message Sodium nitroprusside mediates drought stress responses in tomatoes by modulating nitrosative and oxidative pathways, highlighting the interplay between nitric oxide, hydrogen sulfide, and antioxidant systems for enhanced drought tolerance. Abstract While nitric oxide (NO), a signalling molecule, enhances plant tolerance to abiotic stresses, its precise contribution to improving tomato tolerance to drought stress (DS) through modulating oxide-nitrosative processes is not yet fully understood. We aimed to examine the interaction of NO and nitrosative signaling, revealing how sodium nitroprusside (SNP) could mitigate the effects of DS on tomatoes. DS-seedlings endured 12% polyethylene glycol (PEG) in a 10% nutrient solution (NS) for 2 days, then transitioned to half-strength NS for 10 days alongside control plants. DS reduced total plant dry weight, chlorophyll a and b, Fv/Fm, leaf water potential (ΨI), and relative water content, but improved hydrogen peroxide (H2O2), proline, and NO content. The SNP reduced the DS-induced H2O2 generation by reducing thiol (–SH) and the carbonyl (–CO) groups. SNP increased not only NO but also the activity of l-cysteine desulfhydrase (L-DES), leading to the generation of H2S. Decreases in S-nitrosoglutathione reductase (GSNOR) and NADPH oxidase (NOX) suggest a potential regulatory mechanism in which S-nitrosylation [formation of S-nitrosothiol (SNO)] may influence protein function and signaling pathways during DS. Moreover, SNP improved ascorbate (AsA) and glutathione (GSH) and reduced oxidized glutathione (GSSG) levels in tomato plants under drought. Furthermore, the interaction of NO and H2S, mediated by L-DES activity, may serve as a vital cross-talk mechanism impacting plant responses to DS. Understanding these signaling interactions is crucial for developing innovative drought-tolerance strategies in crops.

“…These differentially expressed genes were discovered to be involved in important physiological activities, such as hormone signaling, other developmental processes, and plant defense against various biotic and abiotic stressors [ 18 , 20 ]. Recent studies showed that applying SNP improved the ability of the rice, soybean, and Mexican lime plants to withstand lead, flooding, salt, and drought stress, respectively [ 5 , 21 , 22 , 23 ]. Therefore, considering the multifaceted role of NO under abiotic stress conditions in different plant species, the present study was conducted to assess the mitigating effects of SNP on Hg, Cr, Cu, and Zn stress in the Korean rice cultivar Jinbu ( Oryza sativa L.).…”

The cultivation of rice is widespread worldwide, but its growth and productivity are hampered by heavy metals stress. However, sodium nitroprusside (SNP), a nitric oxide donor, has been found to be effective for imparting heavy metals stress tolerance to plants. Therefore, the current study evaluated the role of exogenously applied SNP in improving plant growth and development under Hg, Cr, Cu, and Zn stress. For this purpose, heavy metals stress was induced via the application of 1 mM mercury (Hg), chromium (Cr), copper (Cu), and zinc (Zn). To reverse the toxic effects of heavy metals stress, 0.1 mM SNP was administrated via the root zone. The results revealed that the said heavy metals significantly reduced the chlorophyll contents (SPAD), chlorophyll a and b, and protein contents. However, SNP treatment significantly reduced the toxic effects of the said heavy metals on chlorophyll (SPAD), chlorophyll a and b, and protein contents. In addition, the results also revealed that heavy metals significantly increased the production of superoxide anion (SOA), hydrogen peroxide (H2O2), malondialdehyde (MDA), and electrolyte leakage (EL). However, SNP administration significantly reduced the production of SOA, H2O2, MDA, and EL in response to the said heavy metals. Furthermore, to cope with the said heavy metals stress, SNP administration significantly enhanced the activities of superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), and polyphenol peroxidase (PPO). Furthermore, in response to the said heavy metals, SNP application also upregulated the transcript accumulation of OsPCS1, OsPCS2, OsMTP1, OsMTP5, OsMT-I-1a, and OsMT-I-1b. Therefore, SNP can be used as a regulator to improve the heavy metals tolerance of rice in heavy-metals-affected areas.
