“…Given the fact that H 2 S is endogenously produced in plants, it is important to examine its potential physiological roles. Recently, H 2 S was shown to participate in abiotic stress resistance (Zhang et al , 2010Jin et al 2011Jin et al , 2013, in plant defense against pathogen attack (Bloem et al 2004), stomatal movement (García-Mata andLamattina 2010;Lisjak et al 2010), adventitious root organogenesis (Zhang et al 2009), andautophagy (Aìlvarez et al 2012). In our present study, pretreatment with 1.2 mM NaHS for 12 h significantly improved wheat grain germination under NaCl stress.…”

“…Evidence also shows that H 2 S counteracts multiple abiotic stresses including copper, aluminum, salinity and drought stresses, by activating endogenous antioxidant systems Zhang et al 2010;Jin et al 2011;Wang et al 2012;Jin et al 2013). However, whether H 2 S participates in the antioxidant response to salt stress in wheat is still unknown.…”

Hydrogen sulfide (H 2 S) has been recently found to be a gaseous signaling molecule in plants. In this work, we studied the role of H 2 S in alleviating salinity stress during wheat grain germination (Triticum aestivum L. Yangmai 158). Pretreatment with NaHS, a H 2 S donor, during wheat grain imbibition, could significantly attenuate the inhibitory effect of salinity stress on wheat germination. NaHS-pretreated grain showed higher amylase and esterase activities than water control. NaHS pretreatment differentially stimulated the activities of catalase (CAT), guaiacol peroxidase (POD) and ascorbate peroxidase (APX), decreased the level of malondialdehyde (MDA) and reduced NaCl-induced changes in plasma membrane integrity in the radicle tips of seedlings compared with water control. We conclude that H 2 S plays an important role in protecting wheat grain from oxidative damage induced by salinity stress.

“…In plant systems, hydrogen sulfide has been found to play multiple physiological roles in plant growth, development and the acquisition of stress tolerance like heat tolerance (Lisjak et al 2010(Lisjak et al , 2013Li 2013). The novel functions of hydrogen sulfide have been uncovered in seed germination (Zhang et al 2010a;Li et al 2012a), root organogenesis (Zhang et al 2009a) and stomata movement (Lisjak et al 2010;Liu et al 2011;Jin et al 2013), as well as in alleviation in osmotic stress (Zhang et al 2009b), salt stress (Wang et al 2012), oxidative stress (Shan et al 2011, heavy metal stress (Zhang et al 2008(Zhang et al , 2010bChen et al 2013) and pathogen infection (Bloem et al 2011). Our previous results also showed that pretreatment with sodium hydrosulfide (NaHS), a hydrogen sulfide donor, could improve resistance of tobacco cells (Li et al 2012b) and maize seedlings (Li et al 2013a(Li et al ,b, 2014 to high temperature, but its mechanism is not fully clear.…”

Hydrogen sulfide (H2S) is a signal molecule that is involved in plant growth, development and the acquisition of stress tolerance including heat tolerance, but the mechanism of H2S-induced heat tolerance is not completely clear. In present study, the effect of sodium hydrosulfide (NaHS), a H2S donor, treatment on heat tolerance of maize seedlings in relation to antioxidant system was investigated. The results showed that NaHS treatment improved survival percentage of maize seedlings under heat stress in a concentration-dependent manner, indicating that H2S treatment could improve heat tolerance of maize seedlings. To further study mechanism of NaHS-induced heat tolerance, catalase (CAT), guaiacol peroxidase (GPX), superoxide dismutase (SOD), glutathione reductase (GR) and ascorbate peroxidase (APX) activities, and glutathione (GSH) and ascorbic acid (AsA) contents in maize seedlings were determined. The results showed that NaHS treatment increased the activities of CAT, GPX, SOD and GR, and GSH and AsA contents as well as the ratio of reduced antioxidants to total antioxidants [AsA/(AsA+DHA) and GSH/(GSH +GSSG)] in maize seedlings under normal culture conditions compared with the control. Under heat stress, antioxidant enzymes activities, antioxidants contents and the ratio of the reduced antioxidants to total antioxidants in control and treated seedlings all decreased, but NaHS-treated seedlings maintained higher antioxidant enzymes activities and antioxidants levels as well as the ratio of reduced antioxidants to total antioxidants. All of above-mentioned results suggested that NaHS treatment could improve heat tolerance of maize seedlings, and the acquisition of this heat tolerance may be relation to enhanced antioxidant system activity.

“…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.
