“…In this study, we have described a new mechanism by which NaHS treatment promotes the generation of endogenous H 2 S, NO, and H 2 O 2 in apples, thus modulating the mechanism of host resistance ( Figure 2 ). These results are similar to the observations that NaHS increases the contents of endogenous H 2 O 2 and NO in wheat ( Karpets et al, 2020 ) and H 2 S and NO in tomato seedlings ( Liang et al, 2018 ). NaHS is used as a postharvest treatment to delay senescence in kiwifruits ( Zhu et al, 2014 ), mulberries ( Hu H. et al, 2014 ), and strawberries ( Hu et al, 2012 ).…”

“…Endogenous H 2 S activates nitrate reductase (NR), which turns NAD(P)H and nitrate into NAD + and H 2 O. Nitrite is unstable and rapidly decomposes to form NO ( Besson-Bard et al, 2008 ; Liang et al, 2018 ). In addition, H 2 S can activate NADPH oxidase (NOX), which forms O 2 – by transferring electrons, which then produces H 2 O 2 via superoxide dismutase (SOD) ( Karpets et al, 2020 ). Therefore, we infer that NaHS promotes endogenous H 2 S production by activating L/D-CD activity.…”

As a multifunctional signaling molecule, hydrogen sulfide (H2S) has been reported to induce plant responses to a variety of abiotic stresses. However, there are no reports on H2S treatment inducing resistance in apples against Penicillium expansum, a biotic factor, and its possible mechanism of action. In this study, fumigating apples with 5 mM sodium hydrosulfide (NaHS), the exogenous donor of H2S, for 12 h reduced the diameter of lesions in fruit colonized by P. expansum. NaHS treatment markedly promoted the synthesis of endogenous H2S, hydrogen peroxide (H2O2), and nitrogen oxide (NO). In vivo NaHS treatment enhanced the activities of phenylalanine ammonia-lyase, cinnamate 4-hydroxylase, p-coumarate:coenzyme A ligase isoenzymes, caffeoyl-CoA-O-methyltransferase, caffeic acid-O-methyltransferase, ferulic acid-5-hydroxylase, cinnamyl-CoA reductase, and cinnamyl-alcohol dehydrogenase. The treatment also facilitated the production of specific phenolic acids, such as cinnamic acid, p-coumaric acid, caffeic acid, ferulic acid, and sinapic acid; total phenolic compounds; p-coumaryl alcohol; coniferyl alcohol; sinapyl alcohol; and lignin. NaHS treatment induced resistance against P. expansum in apples through H2O2- and NO-mediated activation of phenylpropanoid metabolism.

“…Thus, on the one hand, the effects of antagonism between nitric oxide and hydrogen sulfide are possible, and on the other hand, NO may mediate the signal transduction induced by H 2 S. The involvement of ROS and NO as mediators in stress-protective action of the hydrogen sulfide donor is also indicated by the data obtained on wheat seedlings subjected to heating. Induction of wheat seedlings heat tolerance by the hydrogen sulfide donor NaHS was accompanied by a transient increase in hydrogen peroxide and nitric oxide content in the roots as well as by an increase in nitrate reductase activity ( Karpets et al., 2020 ). The H 2 S donor-induced increase in NO content was not evident in the presence of the antioxidant dimethylthiourea and the NADPH oxidase inhibitor imidazole.…”

The role of nitric oxide and hydrogen sulfide in regulation of redox homeostasis at extreme temperatures in plants

et al. 2023

Nitric oxide and hydrogen sulfide, as important signaling molecules (gasotransmitters), are involved in many functions of plant organism, including adaptation to stress factors of various natures. As redox-active molecules, NO and H2S are involved in redox regulation of functional activity of many proteins. They are also involved in maintaining cell redox homeostasis due to their ability to interact directly and indirectly (functionally) with ROS, thiols, and other molecules. The review considers the involvement of nitric oxide and hydrogen sulfide in plant responses to low and high temperatures. Particular attention is paid to the role of gasotransmitters interaction with other signaling mediators (in particular, with Ca2+ ions and ROS) in the formation of adaptive responses to extreme temperatures. Pathways of stress-induced enhancement of NO and H2S synthesis in plants are considered. Mechanisms of the NO and H2S effect on the activity of some proteins of the signaling system, as well as on the state of antioxidant and osmoprotective systems during adaptation to stress temperatures, were analyzed. Possibilities of practical use of nitric oxide and hydrogen sulfide donors as inductors of plant adaptive responses are discussed.

Hydrogen sulfide (H2S) is a signaling molecule-gasotransmitter that participates in the regulation of many functions of plant organism, including processes of adaptation to stressors of various natures. In recent years, experimental data on the molecular mechanisms of hydrogen sulfide’s action, including posttranslational modification of proteins, and functional relationships of H2S with other cellular mediators — calcium ions, reactive oxygen species (ROS), and nitric oxide — have been intensively accumulated. The review summarizes the latest data on the mechanisms of hydrogen sulfide’s action in the context of its participation in the plants adaptation to the action of stressors. Information on H2S synthesis pathways in plants is also provided. Experimental data on changes in the content of endogenous hydrogen sulfide in plants under the influence of stressors are considered. Information on the stress-protective effect of H2S donors on plants under the action of hypo- and hyperthermia, dehydration, salinity, and heavy metals is presented. The role of hydrogen sulfide in the regulation of antioxidant system, the accumulation of osmolytes, activation of stress protein synthesis is noted. Data on the functional interaction of hydrogen sulfide with ROS and nitric oxide, in particular, competition for thiol groups of proteins, as well as the influence of these mediators on each other’s synthesis are analyzed. Information on the effect of hydrogen sulfide on the synthesis of key plant stress hormones, namely, abscisic, jasmonic, and salicylic acids, and its participation in the transduction of hormonal signals into the genetic apparatus of plant cells is summarized. Possibilities of practical use of hydrogen sulfide donors as inducers of plant resistance are outlined.
