“…Thus, the effects of hydrogen sulfide donors on the state of stomata can have complex dynamics over the time. The reduction of the stomatal aperture and of the relative number of open stomata in Arabidopsis, caused by the hydrogen sulfide donor, was almost completely eliminated by the pretreatment of the leaves with a calcium channel blocker lanthanum chloride, extracellular calcium chelator EGTA, phospholipase C inhibitor neomycin, and an antagonist of the cyclic adenosine-5'-diphosphate ribose formation nicotinamide [234]. Also, the stomatal effect of the H 2 S donor was partially eliminated by the calmodulin antagonist chlorpromazine.…”

“…Nullification of the effect of the hydrogen sulfide donor on the state of the stomatal apparatus of Arabidopsis leaves was also noted as a result of pretreatment of leaves with 1-butanol, an inhibitor of phospholipase D-dependent phosphatidic acid formation. Thus, the results obtained indicate that the calcium influx into the cytosol from various compartments, as well as the formation of lipid signaling mediators, are necessary for the implementation of the hydrogen sulfide effect on the stomata state [234]. Some works were dedicated to the investigation of the CO donor's effect on the resistance of plants to the action of osmotic stress agents (Table 2).…”

Plant adaptive responses to environmental stresses occur with the participation of plant hormones and a network of signaling mediators. Among these, a growing attention has been paid over the recent years to gasotransmitters (GT). This term is used to define small gaseous molecules synthesized by living organisms that perform signaling functions. The main GT in plants are nitrogen monoxide (NO), carbon monoxide (CO), and hydrogen sulfide (H2S). The mechanisms of GT participation in the processes of plant adaptation to unfavorable environmental conditions have not yet been studied enough, which limits the use of GT in crop production. This review summarizes the latest data on GT synthesis in plants, the ability of GT to induce post-translational protein modifications in plants and to functionally interact with each other and with other signaling mediators. Particular attention is paid to the participation of GT in the regulation of antioxidant system, the state of cytoskeleton, and stomatal reactions of plants. These effects are important for stimulation by gasotransmitters the adaptation of plants to extreme temperatures, drought, and salinity. The possibilities of using GT donors in crop production were also considered.

“…Крім того, H 2 S активував експресію генів НАДФН-оксидази й пероксидази клітинної стінки, що, своєю чергою, спричинювало накопичення H 2 O 2 у замикальних клітинах.

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.
