“…Therefore, exogenous Hypotaurine aggravates oxidative damage under low temperature stress. H 2 S can alleviate the membrane peroxidation under low temperature stress by regulating the activity of antioxidant enzymes in hawthorn fruits (Cheng et al, 2016), mitigate the oxidative damage caused by Al by increasing the antioxidant capacity of wheat (Aghdam et al, 2018), and reduce the MDA content by enhancing the activity of antioxidant enzymes in alfalfa seedlings under Cd stress . In addition, H 2 S can also induce the accumulation of ascorbic acid and glutathione in plants to improve its antioxidant capacity (Cui et al, 2014).…”

In this study, we investigated the mechanism of photosynthesis and physiological function of blueberry leaves under low temperature stress (4-6°C) by exogenous hydrogen sulfide (H 2 S) by spraying leaves with 0.5 mmol·L -1 NaHS (H 2 S donor) and 200 mmol·L -1 hypotaurine (Hypotaurine, H 2 S scavenger). The results showed that chlorophyll and carotenoid content in blueberry leaves decreased under low temperature stress, and the photochemical activities of photosystem II (PSII) and photosystem I (PSI) were also inhibited. Low temperature stress can reduce photosynthetic carbon assimilation capacity by inhibiting stomatal conductance (G s ) of blueberry leaves, and non-stomatal factors also play a limiting role at the 5 th day of low temperature stress. Low temperature stress leads to the accumulation of Pro and H 2 O 2 in blueberry leaves and increases membrane peroxidation. Spraying leaves with NaHS, a donor of exogenous H 2 S, could alleviate the degradation of chlorophyll and carotenoids in blueberry leaves caused by low temperature and reduce the photoinhibition of PSII and PSI. The main reason for the enhancement of photochemical activity of PSII was that exogenous H 2 S promoted the electron transfer from Q A to Q B on PSII acceptor side under low temperature stress. In addition, it promoted the accumulation of osmotic regulator proline under low temperature stress and significantly alleviated membrane peroxidation. H 2 S scavengers (Hypotaurine) aggravated photoinhibition and the degree of oxidative damage under low temperature stress. Improving photosynthetic capacity as well as alleviating photosynthetic inhibition and oxidative stress with exogenous H 2 S is possible in blueberry seedlings under low temperature stress.

Hydrogen sulfide (H 2 S) is a highly diffusible, gaseous molecule that has been proved to control a range of physiological responses in many plant stresses. Exposure to UV-B radiation leads to the generation of reactive oxygen species that cause oxidative damages. In this study, sodium hydrosulfide (NaHS) was used as a H 2 S donor for the alleviation of damage caused by UV-B in Borage plant. Lipid peroxidation, protein oxidation, and H 2 O 2 content were increased in plant exposed to UV-B. Results showed that ascorbate peroxidase, guaiacol peroxidase, and catalase activities and reduced glutathione (GSH) did not change significantly in stressed plants when compared with control, but flavonoids concentration was increased considerably. Pre-treatment of plants with NaHS (120 μM), significantly decreased the Malondialdehyde content, carbonyl groups, and H 2 O 2. Activities of ascorbate peroxidase and guaiacol peroxidase enzymes increased in plants which were pre-treated while catalase activity decreased. The reduced glutathione content increased in borage plant leaves. HPLC analysis of flavonoids demonstrated that pre-treatment with NaHS caused a decrease in flavonoid content. These findings suggest that H 2 S alleviates UV-B damages may occur through enhancement of antioxidative enzyme activities and GSH content in borage seedlings.

“…Glyphosate-induced H 2 S released from Arabidopsis [36]. Interestingly, Aghdam et al [37] found that the treatment of hawthorn fruit by exogenous H 2 S under cold stress can lead to a release of endogenous H 2 S. Therefore, Jost et al [38] suggested that H 2 S is produced from L-cysteine in the presence of hydrogen cyanide, which is catalyzed by ß-cyanoalanine synthase in plants, though the mechanism of production under abiotic stress remains to be further studied.…”

“…Notably, H 2 S (0.5 mM NaHS) maintained higher activities of H + -ATPase, cytochrome C oxidase, and succinate dehydrogenase, which consequently enhanced the energy status and improved the chilling tolerance in banana fruit [90]. Meanwhile, Aghdam et al [37] showed that H 2 S also improved the chilling tolerance of hawthorn fruit by increasing antioxidant enzyme activities and promoting phenol accumulation. Thus, these results indicate that H 2 S can regulate the expression of related genes, improve the activity of antioxidant enzymes, and promote the accumulation of phenolic substances to enhance the tolerance of plants challenged by low temperature stress [91].…”

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.
