“…In the last few years, H 2 S as signaling molecule has been much more attention in plant biology, from seed germination, plant growth and development to the response, and adaptation of plants to abiotic and biotic stress ( Zhang et al, 2009 ; Li et al, 2012 , 2014c , 2015 ; Lin et al, 2012 ; Christou et al, 2013 , 2014 ; Fang et al, 2014 ; Li and He, 2015 ; Ma et al, 2015 ; Huo et al, 2018 ). In addition to terrestrial plants, in submerged macrophytes, H 2 S could rapidly induce biochemical responses, photosynthesis, and plant growth, which further adapts to aquatic environment ( Parveen et al, 2017 ). Our previous studies also showed that irrigating of maize seedlings with H 2 S, acting as signaling molecule, could increase the resistance of maize seedlings to high temperature stress ( Li et al, 2013a , b , 2014a , b ; Li and Zhu, 2015 ; Li, 2016 ; Li et al, 2018 ).…”

Hydrogen sulfide (H2S) is a novel type signaling molecule in plants. Seed germination is a key stage of life cycle of plants, which is vulnerable to environmental stress including high temperature. However, under high temperature stress, whether pre-soaking of maize seeds with NaHS (a H2S donor) could improve seed germination and seedling growth and the possible mechanisms are not completely clear. In this study, maize seeds pre-soaked with NaHS enhanced germination percentage, sprout length, root length, and fresh weight compared with the control without NaHS treatment, illustrating that H2S could improve maize seed germination and seedling growth under high temperature. In addition, in comparison to the control, NaHS pre-soaking stimulated antioxidant enzymes [ascorbate peroxidase (APX), glutathione reductase (GR), guaiacol peroxidase (GPX), superoxide dismutase (SOD), and catalase (CAT)] activities and the contents of water soluble non-enzymatic antioxidants [ascorbic acid (AsA) and glutathione (GSH)], as well as the ratio of reduced antioxidant to oxidized antioxidant. Moreover, pre-soaking with NaHS activated Δ1-pyrroline-5-carboxylate synthetase (P5CS) and ornithine aminotransferase [OAT; both are rate-limiting enzymes in proline (Pro) synthesis], betaine aldehyde dehydrogenase [BADH; a key enzyme in glycine betaine (GB)], and trehalose (Tre)-6-phosphate phosphatase (a key step in Tre synthesis), which in turn accumulated Pro, GB, and Tre in germinating seeds compared with the control. Also, an improved germination by NaHS under high temperature was reinforced by the above osmotic adjustment substances (osmolytes) alone, while deteriorated by the inhibitors of osmolyte biosynthesis [gabaculine (GAB), disulfiram (DSF), and sodium citrate (SC)]. These results imply that H2S could improve maize seed germination and seedling growth under high temperature by inducing antioxidant system and osmolyte biosynthesis.

“…The enzymatic antioxidants include superoxide dismutase (SOD), catalase (CAT), guaiacol peroxidase (POD), glutathione peroxidase (GPx), and glutathione S -transferase (GST) and ascorbate peroxidase (APX). Submerged macrophytes have certain physiological adaptations to hypoxia and sulfide toxicity, such as antioxidative enzymes increment [ 17 , 18 ] and anaerobic respiration [ 19 ]. Alcohol dehydrogenase activity (ADH) is an active anaerobic fermentation enzyme that catalyses the terminal step in alcoholic fermentation [ 20 ] and is synthesized favourably under low O 2 concentrations.…”

A hydroponic experiment was performed to investigate the stress responses and biochemical adaptations of four submerged macrophytes, Potamogeton crispus, Myriophyllum spicatum, Egeria densa, and Potamogeton oxyphyllus, to the combined exposure of hypoxia and hydrogen sulfide (H2S, provided by NaHS). The investigated plants were subjected to a control, hypoxia, 0.1mM NaHS, 0.5 mM NaHS, 0.1 mM NaHS+hypoxia and 0.5 mM NaHS+hypoxia conditions. All experimental plants grew optimally under control, hypoxic and NaHS conditions in comparison to that grown in the combined exposure of hypoxia and hydrogen sulfide. For P. crispus and M. spicatum, significant decreases of total chlorophyll and increases in oxidative stress (measured by hydrogen peroxide, H2O2, and malondialdehyde, MDA) were observed with exposure to both sulfide concentrations. However, the decrease in catalase (CAT) and ascorbate peroxidase (APX) from exposure to 0.5 mM NaHS suggests that the function of the protective enzymes reached their limit under these conditions. In contrast, for E. densa and P. oxyphyllus, the higher activities of the three antioxidative enzymes and their anaerobic respiration abilities (ADH activity) resulted in higher tolerance and susceptibility under high sulfide concentrations.

“…Moreover, PN is closely related to contents of photosynthetic pigments. Parveen et al (2017) showed that low concentration of NaHS improved the photosynthesis and the growth of submerged macrophytes. Duan et al (2015) showed that suitable concentration of NaHS improved PN and Chl contents of rice seedlings.…”

“…Besides, we found that gas signal molecule NO was involved in the regulation of above water physiological parameters of Arabidopsis by NaHS. Many studies showed that NaHS improved plant growth (Parveen et al 2017, Chen et al 2018. Chen et al (2018) showed that NaHS ameliorated seed germination and seedling growth of cauliflower under lead stress.…”

“…It has been documented that NaHS improved the growth of rice seedlings and submerged macrophytes by regulating water physiological characteristics, including photosynthesis, chlorophyll (Chl) fluorescence, gas exchange, etc. (Duan et al 2015, Parveen et al 2017.

We investigated the role of nitric oxide (NO) in the regulation of ascorbate-glutathione (AsA-GSH) cycle and water physiological characteristics of Arabidopsis thaliana by sodium hydrosulfide (NaHS). NaHS markedly increased the contents of H2S, NO, chlorophyll (Chl), and carotenoids, the activity of AsA-GSH cycle, ascorbate/dehydroascorbate ratio, net photosynthetic rate, Chl fluorescence parameters, transpiration rate, stomatal conductance, and relative water content in leaves and the biomass of wild-type Arabidopsis. However, NaHS markedly decreased malondialdehyde content and electrolytic leakage. Except H2S, above NaHS-induced promotions were suppressed by nitrate reductase (NR) inhibitor sodium azide (NaN3). Application of sodium nitroprusside (SNP) to (NaN3+NaHS)-treated wild type Arabidopsis (NaN3+SNP+NaHS) reversed above effects of NaN3+NaHS. However, NaN3+NaHS and NaN3+SNP+NaHS had no significant effects on H2S content. Meanwhile, we proved above results by using NO-associated NR gene mutant nia1,nia2. Above results suggested that NO participated in the regulation of AsA-GSH cycle and water physiological characteristics of Arabidopsis by NaHS.
