“…Meanwhile, the study of Li et al shows that spraying NaHS improves heat tolerance in maize by alleviating the increase of electrolyte leakage and MDA [39]. In addition, Zhang and his colleagues indicate that spraying NaHS delays excessive accumulation of MDA and reactive oxygen species, but enhance SOD activity against cooper stress and droughtinduced oxidative stress in wheat seeds and soybean seedlings [11,15]. All these findings suggest that H 2 S possibly use the similar mechanism to resist various stresses in different plants.…”

“…Recent studies show that H 2 S is involved not only in plant responses to drought and copper stresses but also in tolerance to salinity, heat, cadmium, boron and chromium stresses [6][7][8][9][10]. It is reported that exogenous H 2 S can enhance the resistance of plants to drought stress [11][12][13][14] and copper stress [15,16] by improving the activities of antioxidant enzymes, such as superoxide dismutase (SOD), catalase (CAT), and peroxidase (POD). However, whether endogenous H 2 S is involved in plant cold stress response is poorly known.…”

Hydrogen sulfide (H 2 S) is an important signaling molecule involved in several stress-resistance processes in plants, such as drought and heavy metal stresses. However, little is known about the roles of H 2 S in responses to chilling stress. In this paper, we demonstrated that chilling stress enhance the H 2 S levels, the H 2 S synthetase (L-/D-cysteine desulfhydrase, L/DCD) activities, and the expression of L/DCD gene in Vitis vinifera L. 'F-242' . Furthermore, the seedlings were treated with sodium hydrosulfide (NaHS, a H 2 S donor) and hypotaurine (HT, a H 2 S scavenger) at 4°C to examine the effects of exogenous H 2 S on grape. The results revealed that the high activity of superoxide dismutase and enhanced expression of VvICE1 and VvCBF3 genes, but low level of superoxide anion radical, malondialdehyde content and cell membrane permeability were detected after addition of NaHS. In contrast, HT treatment displayed contrary effect under the chilling temperature. Taken together, these data suggested that H 2 S might be directly involved in the cold signal transduction pathway of grape.

“…Early studies concerning H 2 S emission in plants were associated with the plant response to pathogens as part of a so-called Sulfur Induced Resistance (Bloem et al, 2004). Using a H 2 S-releasing compound, H 2 S was later reported to confer a protective effect against oxidative (Zhang et al, 2009b(Zhang et al, , 2010b and cadmium (Sun et al, 2013) stresses, alleviate aluminum toxicity (Zhang et al, 2010c), increase antioxidant activity, and participate in root organogenesis (Zhang et al, 2009a). Several independent groups have recently reported the participation of H 2 S in ABA-and ethylene-dependent stomatal closure induction (García-Mata and Lamattina, 2010;Liu et al, 2011Liu et al, , 2012Jin et al, 2013).…”

Hydrogen Sulfide Generated byl-Cysteine Desulfhydrase Acts Upstream of Nitric Oxide to Modulate Abscisic Acid-Dependent Stomatal Closure

Abscisic acid (ABA) is a well-studied regulator of stomatal movement. Hydrogen sulfide (H 2 S), a small signaling gas molecule involved in key physiological processes in mammals, has been recently reported as a new component of the ABA signaling network in stomatal guard cells. In Arabidopsis (Arabidopsis thaliana), H 2 S is enzymatically produced in the cytosol through the activity of L-cysteine desulfhydrase (DES1). In this work, we used DES1 knockout Arabidopsis mutant plants (des1) to study the participation of DES1 in the cross talk between H 2 S and nitric oxide (NO) in the ABA-dependent signaling network in guard cells. The results show that ABA did not close the stomata in isolated epidermal strips of des1 mutants, an effect that was restored by the application of exogenous H 2 S. Quantitative reverse transcription polymerase chain reaction analysis demonstrated that ABA induces DES1 expression in guard cell-enriched RNA extracts from wild-type Arabidopsis plants. Furthermore, stomata from isolated epidermal strips of Arabidopsis ABA receptor mutant pyrabactin-resistant1 (pyr1)/pyrabactin-like1 (pyl1)/pyl2/pyl4 close in response to exogenous H 2 S, suggesting that this gasotransmitter is acting downstream, although acting independently of the ABA receptor cannot be ruled out with this data. However, the Arabidopsis clade-A PROTEIN PHOSPHATASE2C mutant abscisic acid-insensitive1 (abi1-1) does not close the stomata when epidermal strips were treated with H 2 S, suggesting that H 2 S required a functional ABI1. Further studies to unravel the cross talk between H 2 S and NO indicate that (1) H 2 S promotes NO production, (2) DES1 is required for ABA-dependent NO production, and (3) NO is downstream of H 2 S in ABA-induced stomatal closure. Altogether, data indicate that DES1 is a unique component of ABA signaling in guard cells.Abscisic acid (ABA) regulates diverse physiological and developmental processes in plants, among which seed dormancy and stomatal movement are the most studied. Stomata are pores bordered by pairs of specialized cells named guard cells located in the epidermis of the aerial part of most land plants. Due to the waxy cuticle of plants, stomatal pores regulate approximately 90% of all the gas exchange (i.e. the uptake of CO 2 required for photosynthesis and the loss of water vapor during transpiration) between the plant and the environment (Hetherington and Woodward, 2003). Thus, stomatal movement is a key process for the regulation of plant water status and biomass production. In guard cells, ABA induces an increase of intracellular calcium concentrations, which, in turn, induces an efflux of anions that causes membrane depolarization. In this voltage milieu, ion uptake is blocked through the inactivation of inward-rectifying potassium channels, and ion efflux is induced through activation of outward-rectifying potassium channels. This solute relocation drives water out of the guard cells and closes the stomatal pore as a result of a reduction in guard cell turgor (Blatt, 2000;Kim et al...

“…One of the most Environment restricting factors negatively affecting plant growth in the majority of the world's agricultural lands could be defined as a drought stress (Tas and Tas, 2007), and greatly limits crop production worldwide (Zhang et al, 2010). As a common consequence of drought stress, the production of reactive oxygen species (ROS), such as superoxide radical (O 2-), hydrogen peroxide (H 2 O 2 ), and hydroxyl radical (OH) is increased (Valentovic et al, 2006) which is due to the enhanced leakage of electrons to molecular oxygen (Arora et al, 2002).…”

Abstract. To study water-stress-tolerant barley varieties, 20 barley lines were cultivated under full irrigation and limited irrigation conditions where irrigation was stopped at anthesis stage in two separate field experiments during the 2007-2009 growing seasons at the Saatloo Research Farm, Azerbaijan, Iran. The experiments were laid out using RCBD with three replications. The results from combined analysis of variance in both normal and stress conditions indicated that there were significant differences among genotypes with regard to all studied traits which were due to high variation among the genotypes. It was found that the activity of enzymes including SOD, GPX and CAT were increased under drought stress conditions, so that tolerant genotypes had more changes in enzyme activity. On the other hand, MDA, Dityrosine and 8-oHdg were increased under stress conditions where sensitive genotypes had stronger enzyme activity. Calculations of the correlation coefficients among the studied traits under both stress and normal conditions also indicated that there were negative and significant differences between antioxidant activity, lipid, protein, and DNA decadence. Finally, with regard to all traits, it was revealed that in normal conditions genotypes 18 and 19 were the best performing lines, whereas the genotype 14 was least adapted line. Therefore, genotypes 18 and 19 showed higher levels of resistance to water stress and the genotype 15 was more sensitive to the drought conditions. The results also indicated that selecting more tolerant genotypes under stress conditions was the way to overcome water deficit stress under terminal drought conditions.
