“…In our study, SNP pre-treatment alleviated the detrimental effects of NaCl stress on seedling growth. These results have also been shown in many plant species exposed to NaCl stress (4,7,8). It has been reported that NO can loosen the cell wall, affect the phospholipid layer, increase membrane fluidity, and promote plant growth by increasing cell expansion (21).…”

“…Dong et al (22) re-ported that NO increases stem and root elongation by improving cytoplasmic viscosity and increasing the osmotic pressure under high salinity. However, it has been demonstrated that NO-mediated induction of salt tolerance is associated with increased activities of antioxidant enzymes and the accumulation of osmoprotectans (4,8). Additionally, NO has been shown to interact with salicylic acid and hydrogen peroxide to mediate the elimination of oxidative damage in many stress conditions (23).…”

“…Different mechanisms have been suggested for NO-mediated salt tolerance. Yadu et al (8) and Ahmad et al (4) have demonstrated that NO improved the salinity tolerance of pea and tomato seedlings by enhancing the antioxidant capacity and synthesis of flavonoid, glycine betaine, and proline. Exogenous application of SNP has also been shown to improve photosynthetic capacity by protecting pigments, enhancing quantum-yield of photosystem II, and increasing stomatal conductance and RuBisCO activity (9,10).…”

Objective: The salinization of agricultural soils poses a serious challenge across the world. Although recent studies have shown that exogenous sodium nitroprusside (SNP) application can alleviate the harmful effects of salinity, the roles of SNP in the regulation of proteomic changes remain poorly understood. Materials and Methods:To unravel the protective roles of exogenous SNP in alleviating salt-induced damage in barley (Hordeum vulgare L.), proteomic analysis was carried out on the leaves of seedlings exposed to 100 mM NaCl stress following 200 µM SNP pre-treatment.Results: Our results indicated that SNP pre-treatment restored the seedling growth reduced by salinity stress. Comparing 2-DE gels from the treatments showed that 24 proteins were differentially accumulated under SNP and/or NaCl stress treatments. Among them, 15 proteins were identified by matrix-assisted laser desorption ionization time-of-flight mass spectrometry. Gene ontology analysis demonstrated that several pathways were regulated by SNP and/or NaCl treatments, including photosynthesis, protein metabolism, stress defense, and energy metabolism. Exogenous SNP increased the expression levels of 20 kDa chaperonin, proteasome subunit beta type-2, 2-Cys peroxiredoxin BAS1, ferredoxin-NADP reductase, thiazole biosynthetic enzyme 1-1, S-adenosylmethionine synthetase 3, and elongation factor Tu proteins in the leaves of barley seedlings under NaCl stress. Conclusion:Our results indicate that SNP pre-treatment may induce salinity tolerance through regulation of photosynthesis, activation of stress defence, degradation of damaged proteins, and the promoting of the synthesis of polyamines, proline, and GABA.

“…In addition, NO improved the salt tolerance of Jatropha curcas during the establishment of seedlings by inducing an effective antioxidant system, thus inhibiting toxic ions and ROS accumulation, alleviating oxidative stress, and activating the antioxidant defense system [100]. Further, the application of sodium nitroprusside (source of NO) significantly mitigated growth inhibition and enhanced the contents of antioxidants and osmoprotectants in salt-challenged Pisum sativum L. [99]. Moreover, the NO donor sodium nitroprusside upregulated antioxidant defense mechanisms and increased ascorbic acid (AsA) contents and total phenolic contents (TPC), thereby effectively increasing the growth and grain yield of wheat under salinity stress [1] (Table 3).…”

Abiotic stress is one of the major threats affecting plant growth and production. The harm of abiotic stresses includes the disruption of cellular redox homeostasis, reactive oxygen species (ROS) production, and oxidative stress in the plant. Plants have different mechanisms to fight stress, and these mechanisms are responsible for maintaining the required homeostasis in plants. Recently, the study of gasotransmitters in plants has attracted much attention, especially for abiotic stress. In the present review, abiotic stressors were mostly found to induce gasotransmitter production in plants. Meanwhile, these gasotransmitters can enhance the activity of several antioxidant enzymes, alleviate the harmfulness of ROS, and enhance plant tolerance under various stress conditions. In addition, we introduced the interaction of gasotransmitters in plants under abiotic stress. With their promising applications in agriculture, gasotransmitters will be adopted in the near future.Plants 2019, 8, 605 2 of 23 unique and regulate specific biological functions. Gasotransmitters have long been of great interest in a wide range of fields. Over the past few decades, the roles of these signaling molecules have been extensively studied for their biological applications. Recently, the emissions of endogenous gasotransmitters in plants have been widely studied and analyzed, thereby providing information to facilitate our understanding of new gasotransmitter signaling pathways. Previous studies found that in response to abiotic stressors, plants usually produce these gasotransmitters [12][13][14]. In addition, there is now considerable evidence to show that gasotransmitters can play a pivotal role in enhancing plant tolerance [2,15,16]. Subsequently, biological gases from complex extra and intracellular pathways and gas mediators may regulate many processes in an antagonistic or synergistic way.In the present review, we introduce the production of gasotransmitters in plants under abiotic stress. Meanwhile, we focused on the recent advances in the roles of gasotransmitters under abiotic stresses and their interaction with other gasotransmitters.

Arsenic (As) is a toxic metalloid, severely affecting the normal functioning of plants, animals, and human beings. Nitric oxide (NO) and dimethylthiourea (DMTU) are two potential compounds play key roles in enhancing tolerance against a variety of abiotic stresses in plants. In the present study, ameliorating abilities of both NO and DMTU against As‐induced disturbances in Glycine max L. have been investigated. Overall results revealed that As accrual significantly suppressed seed germination, radicle length, and biomass accumulation. The oxidative stress markers such as membrane integrity, contents of reactive oxygen species, and malondialdehyde, and lipoxygenase activity were enhanced by As treatment. Pronounced decreases in protein and DNA contents with a concomitant increase in DNA oxidation were observed in the growing radicles after exposure to As. In addition, treatment of As also revealed elevation in the activity and gene expression of pyrroline‐5‐carboxylate synthetase, in parallel to both proline and sugar accumulation. However, the toxic effects of As were partially/ to a large extent reversed by the exogenous application of NO and DMTU, separately, in Glycine max L. Moreover, between these two treatments, NO was more efficient than the DMTU against As‐induced oxidative stress responses in Glycine max L. Our findings provide a foundation to minimize the toxic effects of As in crop plants worldwide. © 2018 American Institute of Chemical Engineers Environ Prog, 38: 402–409, 2019
