Nitric Oxide and Hydrogen Sulfide Coordinately Reduce Glucose Sensitivity and Decrease Oxidative Stress via Ascorbate-Glutathione Cycle in Heat-Stressed Wheat (Triticum aestivum L.) Plants

Antioxidants, Journal Year: 2021, Volume and Issue: 10(1), P. 108 - 108

Published: Jan. 14, 2021

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

γ-Aminobutyrate (GABA) Regulated Plant Defense: Mechanisms and Opportunities

Plants, Journal Year: 2021, Volume and Issue: 10(9), P. 1939 - 1939

Published: Sept. 17, 2021

Global climate change and associated adverse abiotic biotic stress conditions affect plant growth development, agricultural sustainability in general. Abiotic stresses reduce respiration energy generation mitochondria, resulting the elevated production of reactive oxygen species (ROS), which are employed to transmit cellular signaling information response changing conditions. Excessive ROS accumulation can contribute cell damage death. Production non-protein amino acid γ-aminobutyrate (GABA) is also stimulated, partial restoration respiratory processes production.

Thiol-based Oxidative Posttranslational Modifications (OxiPTMs) of Plant Proteins

Plant and Cell Physiology, Journal Year: 2022, Volume and Issue: 63(7), P. 889 - 900

Published: March 21, 2022

Abstract The thiol group of cysteine (Cys) residues, often present in the active center protein, is particular importance to protein function, which significantly determined by redox state a protein’s environment. Our knowledge different thiol-based oxidative posttranslational modifications (oxiPTMs), compete for specific groups, has increased over last 10 years. principal oxiPTMs include S-sulfenylation, S-glutathionylation, S-nitrosation, persulfidation, S-cyanylation and S-acylation. role each oxiPTM depends on cellular state, turn homeostasis under either optimal or stressful conditions. Under such conditions, metabolism molecules as glutathione, NADPH (reduced nicotinamide adenine dinucleotide phosphate), nitric oxide, hydrogen sulfide peroxide can be altered, exacerbated and, consequently, outside cell’s control. This review provides broad overview these physiological unfavorable regulate function target proteins.

Nitric oxide and hydrogen sulfide, as important signaling molecules (gasotransmitters), are involved in many functions of plant organism, including adaptation to stress factors various natures. As redox-active molecules, NO H 2 S redox regulation functional activity proteins. They also maintaining cell homeostasis due their ability interact directly indirectly (functionally) with ROS, thiols, other molecules. The review considers the involvement nitric sulfide responses low high temperatures. Particular attention is paid role gasotransmitters interaction mediators (in particular, Ca 2+ ions ROS) formation adaptive extreme Pathways stress-induced enhancement synthesis plants considered. Mechanisms effect on some proteins system, well state antioxidant osmoprotective systems during temperatures, were analyzed. Possibilities practical use donors inductors discussed.
