International Journal of Molecular Sciences, Journal Year: 2024, Volume and Issue: 25(12), P. 6598 - 6598

Published: June 15, 2024

Hydrogen sulfide (H2S) is a novel gasotransmitter. Sucrose (SUC) source of cellular energy and signaling molecule. Maize the third most common food crop worldwide. However, interaction H2S SUC in maize thermotolerance not widely known. In this study, using seedlings as materials, metabolic functional interactions were investigated. The data show that under heat stress, survival rate tissue viability increased by exogenous SUC, while malondialdehyde content electrolyte leakage reduced indicating could increase thermotolerance. Also, SUC-promoted was enhanced H2S, separately weakened an inhibitor (propargylglycine) scavenger (hypotaurine) SUC-transport (N-ethylmaleimide), suggesting development To establish underlying mechanism H2S–SUC interaction-promoted thermotolerance, redox parameters mesocotyls measured before after stress. indicate activity gene expression H2S-metabolizing enzymes up-regulated whereas had no significant effect on SUC-metabolizing enzymes. addition, catalase, glutathione reductase, ascorbate peroxidase, dehydroascorbate monodehydroascorbate superoxide dismutase reinforced their combination non-heat conditions to varying degrees. Similarly, ascorbic acid, flavone, carotenoid, polyphenol combination, production radicals hydrogen peroxide level impaired these treatments different extents. These results imply sucrose exist formation through homeodynamics. This finding lays theoretical basis for developing climate-resistant crops improving security.

Cotton is an important cash crop in addition to being a fiber commodity, and it plays essential part the economies of numerous nations. High temperature most critical element affecting its yield from fertilization harvest. The optimal for root formation 30 C -35 °C; however, development ends around 40 °C. Increased temperature, particular, influences different biochemical physiological processes associated with cotton plant, resulting low seed production. Many studies various agroecological zones used agronomic strategies contemporary breeding techniques reduce heat stress improve productivity. To attain desired traits, breeders should investigate all potential possibilities, such as generating superior cultivars by traditional breeding, employing molecular transgenic methods, using genome editing techniques. main objective this review provide recent information on environmental factors, drought, influence growth development, morphology physio-chemical alteration cotton. Furthermore, advancement combat serious threat drought stress.

NO and H2S Contribute to Crop Resilience against Atmospheric Stressors

International Journal of Molecular Sciences, Journal Year: 2024, Volume and Issue: 25(6), P. 3509 - 3509

Published: March 20, 2024

Atmospheric stressors include a variety of pollutant gases such as CO2, nitrous oxide (NOx), and sulfurous compounds which could have natural origin or be generated by uncontrolled human activity. Nevertheless, other atmospheric elements including high low temperatures, ozone (O3), UV-B radiation, acid rain among others can affect, at different levels, large number plant species, particularly those agronomic interest. Paradoxically, both nitric (NO) hydrogen sulfide (H2S), until recently were considered toxic since they are part the polluting gases; however, present, these molecules mechanism response to multiple stresses exert signaling functions usually an associated stimulation enzymatic non-enzymatic antioxidant systems. At gasotransmitters essential components defense against wide range environmental ones. This review aims provide updated vision endogenous metabolism NO H2S in cells deepen how exogenous application contribute crop resilience, particularly, stimulating

The Essential Role of H2S-ABA Crosstalk in Maize Thermotolerance through the ROS-Scavenging System

International Journal of Molecular Sciences, Journal Year: 2023, Volume and Issue: 24(15), P. 12264 - 12264

Published: July 31, 2023

Hydrogen sulfide (H2S) and abscisic acid (ABA), as a signaling molecule stress hormone, their crosstalk-induced thermotolerance in maize seedlings its underlying mechanism were elusive. In this paper, H2S ABA crosstalk well the of investigated. The data show that endogenous levels could be mutually induced by regulating metabolic enzyme activity gene expression under non-heat (non-HS) HS conditions. Furthermore, alone or combination significantly increase improving survival rate (SR) mitigating biomembrane damage. Similarly, reactive oxygen species (ROS)-scavenging system, including enzymatic antioxidants catalase (CAT), ascorbate peroxidase (APX), guaiacol (POD), glutathione reductase (GR), monodehydroascorbate (MDHAR), dehydroascorbate (DHAR), superoxide dismutase (SOD), non-enzymatic reduced ascorbic (AsA), carotenoids (CAR), flavone (FLA), total phenols (TP), was enhanced seedlings. Conversely, ROS level (mainly hydrogen peroxide radical) weakened non-HS These imply ROS-scavenging system played an essential role H2S-ABA

Ammonia (NH3), as an intermediate product of nitrogen metabolism, is recognized a novel gasotransmitter (namely gaseous signaling molecule), its role being revealed in plants. NH3 exists two different chemical forms, namely the weak base (free molecule: NH3) and acid (ammonium: NH4+), which are generally equilibrium with each other However, effect on seed germination, seedling growth, thermotolerance acquirement maize remains unclear. Here, seeds were imbibed concentrations NH3·H2O (NH3 donor), then germinated calculated germination rate at various time points. Also, 60-h-old seedlings irrigated NH3·H2O, subjected to heat stress counted survival rate. The data implied that appropriate (6, 9, 12 mM) accelerated well increased height root length compared control without treatment. suitable (2 4 improved tissue vitality, relieved increase malondialdehyde content, enhanced under control.
