“…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.…”

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 plants, numerous studies have shown that sulfide increases tolerance/resistance against stress conditions, such as metal stress (Zhang et al 2008 ;Dawood et al 2012 ;Wang et al 2010 ;Sun et al 2013 ;, drought (Jin et al 2011 ), hypoxia (Cheng et al 2013 ), salinity (Christou et al 2013 ;Wang et al 2012 ), and heat . Moreover, sulfide has been also demonstrated to regulate many essential plant processes, like photosynthesis (Chen et al 2011 ), stomatal movement (Garcia-Mata and Lamattina 2010 ;Lisjak et al 2010 ), flower senescence (Zhang et al 2011 ), and postharvest life of fruits (Hu et al 2012 ). Therefore, because DES1 catalyzes the enzymatic desulfuration of Cys to sulfide, the DES1 mutation provokes a reduction in the capacity of the cytosol to release sulfide.…”

Signaling in the plant cytosol: cysteine or sulfide?

Cysteine (Cys) is the first organic compound containing reduced sulfur that is synthesized in the last stage of plant photosynthetic assimilation of sulfate. It is a very important metabolite not only because it is crucial for the structure, function and regulation of proteins but also because it is the precursor molecule of an enormous number of sulfur-containing metabolites essential for plant health and development. The biosynthesis of Cys is accomplished by the sequential reaction of serine acetyltransferase (SAT) and O-acetylserine(thiol)synthase (OASTL). In Arabidopsis thaliana, the analysis of specific mutants of members of the SAT and OASTL families has demonstrated that the cytosol is the compartment where the bulk of Cys synthesis takes place and that the cytosolic OASTL enzyme OAS-A1 is the responsible enzyme. Another member of the OASTL family is DES1, a novel L-cysteine desulfhydrase that catalyzes the desulfuration of Cys to produce sulfide, thus acting in a manner opposite to that of OAS-A1. Detailed studies of the oas-a1 and

“…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.
