“…H 2 S is reported to protect plants from heat stress [ 6 , 7 ] by regulating stomatal movement [ 8 , 9 , 10 ], photosynthesis [ 11 ], and antioxidative enzyme activities [ 12 ]. Because of the similarity of their physiological effects, H 2 S and NO crosstalk under different stresses are gaining attention [ 13 , 14 , 15 , 16 , 17 , 18 ]. Both are small uncharged molecules and can easily diffuse in inter- or intracellular spaces without the need of any carrier or transporter [ 16 ].…”

“…Besides, the combined application of SNP and H 2 S more efficiently reduced heat stress, which was eliminated by the application of H 2 S inhibitors and scavenger, suggesting that H 2 S may act as a downstream signalling agent in NO-mediated heat stress tolerance in maize seedlings [ 6 ]. However, H 2 S may act upstream or downstream of NO in the signalling cascade [ 18 ], and multifaceted connections occur between NO and H 2 S involved in various physiological functions and pathways [ 17 ]. The positive interaction between H 2 S and NO is reported in bermudagrass under cadmium (Cd) stress [ 21 ] in Pisum sativum under arsenate stress (AsV) [ 22 ], in maize seedling under chromium stress [ 23 , 24 ], and in wheat under Cd stress [ 25 ].…”

The involvement of nitric oxide (NO) and hydrogen sulfide (H2S) in countermanding heat-inhibited photosynthetic features were studied in wheat (Triticum aestivum L.). Heat stress (HS) was employed at 40 °C after establishment for 6 h daily, and then plants were allowed to recover at 25 °C and grown for 30 days. Glucose (Glc) content increased under HS and repressed plant photosynthetic ability, but the application of sodium nitroprusside (SNP, as NO donor) either alone or with sodium hydrosulfide (NaHS, as H2S donor) reduced Glc-mediated photosynthetic suppression by enhancing ascorbate-glutathione (AsA-GSH) metabolism and antioxidant system, which reduced oxidative stress with decreased H2O2 and TBARS content. Oxidative stress reduction or inhibiting Glc repression was maximum with combined SNP and NaHS treatment, which was substantiated by 2-4-carboxyphenyl-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide (cPTIO) and hypotaurine (HT), scavengers for NO and H2S, respectively. The scavenge of H2S reduced NO-mediated alleviation of HS suggesting of its downstream action in NO-mediated heat-tolerance. However, a simultaneous decrease of both (NO and H2S) led to higher Glc-mediated repression of photosynthesis and oxidative stress in terms of increased H2O2 content that was comparable to HS plants. Thus, NO and H2S cooperate to enhance photosynthesis under HS by reducing H2O2-induced oxidative stress and excess Glc-mediated photosynthetic suppression.

“…At higher concentrations, NO induces nitro‐oxidative stress, whereas it acts as a signaling molecule at low concentrations (Arora et al, 2016). H 2 S is also cytotoxic at higher concentrations and elicits various defense responses against abiotic stresses and alleviates nitro‐oxidative damage (Corpas, 2019a, 2019b). NO and H 2 S modulate protein activity, GSH biosynthesis, metal nitrosylation, tyrosine nitration/peroxynitrite formation, S‐nitrosylation, S‐glutathionylation, and sulfhydration (Farnese et al, 2016).…”

NO and H 2 S belong to a family of reactive nitrogen and sulfur species (RNS and RSS), respectively (Corpas, 2019a, 2019b) and can be generated simultaneously (Niu & Liao, 2016). NO and H 2 S modulate protein activity, GSH biosynthesis, metal nitrosylation, tyrosine nitration/peroxynitrite formation, S‐nitrosylation, S‐glutathionylation, and sulfhydration.…”

The agriculture sector is vulnerable to various environmental stresses, which significantly affect plant growth, performance, and development. Abiotic stresses, such as salinity and drought, cause severe losses in crop productivity worldwide. Soil salinity is a major stress suppressing plant development through osmotic stress accompanied by ion toxicity, nutritional imbalance, and oxidative stress. Various defense mechanisms like osmolytes accumulations, activation of stress‐induced genes, and transcription factors, production of plant growth hormones, accumulation of antioxidants, and redox defense system in plants are responsible for combating salt stress. Nitric oxide (NO) and hydrogen sulphide (H2S) have emerged as novel bioactive gaseous signaling molecules that positively impact seed germination, homeostasis, plant metabolism, growth, and development, and are involved in several plant acclimation responses to impart stress tolerance in plants. NO and H2S trigger cell signaling by activating a cascade of biochemical events that result in plant tolerance to environmental stresses. NO‐ and H2S‐mediated signaling networks, interactions, and crosstalks facilitate stress tolerance in plants. Research on the roles and mechanisms of NO and H2S as challengers of salinity is entering an exponential exploration era. The present review focuses on the current knowledge of the mechanisms of stress tolerance in plants and the role of NO and H2S in adaptive plant responses to salt stress and provides an overview of the signaling mechanisms and interplay of NO and H2S in the regulation of growth and development as well as modulation of defense responses in plants and their long term priming effects for imparting salinity tolerance in plants.

“…NO might be located upstream of H 2 S in Bermuda grass's response to Cd stress by regulating antioxidant enzyme activities (SOD, CAT, POD, and GR) and the nonenzymatic GSH redox state, thus keeping MDA and cell damage at relatively low levels and enhancing Cd tolerance [32] (Figure 2c). NO and H 2 S, which mediate various signaling networks, are crucial elements in the biochemistry and physiology of plants [118]. Together, the synergistic or antagonistic effects of H 2 S and NO might play important roles in the regulation of abiotic stress.…”

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.
