TLDR
This review will provide a comprehensive update on these two gasotransmitters in physiological processes (seed germination, root development, stomatal movement, leaf senescence and fruit ripening) and under adverse environmental conditions.Abstract:
Nitric oxide (NO) is a signal molecule regarded as being involved in myriad functions in plants under physiological, pathogenic, and adverse environmental conditions. Hydrogen sulfide (H2S) has also recently been recognized as a new gasotransmitter with a diverse range of functions similar to those of NO. Depending on their respective concentrations, both these molecules act synergistically or antagonistically as signals or damage promoters in plants. Nevertheless, available evidence shows that the complex biological connections between NO and H2S involve multiple pathways and depend on the plant organ and species, as well as on experimental conditions. Cysteine-based redox switches are prone to reversible modification; proteomic and biochemical analyses have demonstrated that certain target proteins undergo post-translational modifications such as S-nitrosation, caused by NO, and persulfidation, caused by H2S, both of which affect functionality. This review provides a comprehensive update on NO and H2S in physiological processes (seed germination, root development, stomatal movement, leaf senescence, and fruit ripening) and under adverse environmental conditions. Existing data suggest that H2S acts upstream or downstream of the NO signaling cascade, depending on processes such as stomatal closure or in response to abiotic stress, respectively.read more

TL;DR: It is shown that ABA stimulates the persulfidation of l-CYSTEINE DESULFHYDRASE1, an important endogenous H2S enzyme, at Cys44 and Cys205 in a redox-dependent manner, and s-persulfidation-induced RBOHD activity is relevant to ABA-induced stomatal closure.

TL;DR: A scenario is depicted where the regulation of catalase through PTMs, especially S-nitrosation and persulfidation, is highlighted and peroxisomes is assigned a crucial statement in the signaling crossroads among relevant molecules (NO and H2S), since catal enzyme is allocated in these organelles.

Nitric oxide release accounts for the biological activity of endothelium-derived relaxing factor
TL;DR: NO released from endothelial cells is indistinguishable from EDRF in terms of biological activity, stability, and susceptibility to an inhibitor and to a potentiator.
Journal ArticleDOI
Endothelium-derived relaxing factor produced and released from artery and vein is nitric oxide.
TL;DR: The vascular effects of EDRF released from perfused bovine intrapulmonary artery and vein were compared with the effects of NO delivered by superfusion over endothelium-denuded arterial and venous strips arranged in a cascade to determine whether nitric oxide (NO) is responsible for the vascular smooth muscle relaxation elicited by endothelia-derived relaxing factor (EDRF).

The possible role of hydrogen sulfide as an endogenous neuromodulator
Kazuho Abe,Hideo Kimura +1 more
TL;DR: It is shown that physiological concentrations of H2S selectively enhance NMDA receptor-mediated responses and facilitate the induction of hippocampal long-term potentiation, suggesting that endogenous H 2S functions as a neuromodulator in the brain.

TL;DR: It is shown that nitric oxide potentiates the induction of hypersensitive cell death in soybean cells by reactive oxygen intermediates and functions independently of such intermediates to induce genes for the synthesis of protective natural products.

Physiological Implications of Hydrogen Sulfide: A Whiff Exploration That Blossomed
TL;DR: The important life-supporting role of hydrogen sulfide (H(2)S) has evolved from bacteria to plants, invertebrates, vertebrate, vertebrates, and finally to mammals, but over the centuries it had only been known for its toxicity and environmental hazard.
