“…Thus, CO is regarded as a physiological messenger or bioactive molecular, and most of its effects were mediated by the activation of soluble guanylyl cyclase (sGC) or by hyperpolarizing membrane potentials through the mechanisms involving stimulation of potassium channels (Piantadosi, 2002;Dulak and Józkowicz, 2003). Similarly, some recent investigations of the functional roles of hemin and HO/CO system in plants, including the hormone-like effects on adventitious root and lateral root formation (Xuan et al, 2008;Cao et al, 2011;Lin et al, 2012) and the protection against salinity stress (Xie et al, 2008, have greatly extended our understanding of this signal system as a cellular defense mechanism against abiotic stresses-related and various other developmental processes both in animals and plants.…”

“…It was well known that H 2 S is a critical signal in animals, important for various physiological functions, including anti-inflammatory role, the induction of hippocampal long-term potentiation, brain development and blood pressure regulation (Wang 2003;Lefer 2007;Li et al 2009). In plants, H 2 S has been implicated in various development processes, such as adventitious root and lateral root formation (Zhang et al 2009a;Lin et al 2012), and seed germination Wang et al 2012). On the other hand, it has been suggested that H 2 S can act as a potential antioxidant in plants upon abiotic stresses by efficiently inducing changes in transcripts of genes encoding pectin methylesterase (PME) , or total and isozymatic activities of antioxidative enzymes (Zhang et al 2009b(Zhang et al , 2010a.…”

Despite hydrogen sulfide (H(2)S) and nitric oxide (NO) are important endogenous signals or bioregulators involved in many vital aspects of plant growth and responses against abiotic stresses, little information was known about their interaction. In the present study, we evaluated the effects of H(2)S and NO on alfalfa (Medicago sativa L.) plants exposed to cadmium (Cd) stress. Pretreatment with an H(2)S donor sodium hydrosulfide (NaHS) and well-known NO donor sodium nitroprusside (SNP) decreased the Cd toxicity. This conclusion was supported by the decreases of lipid peroxidation as well as the amelioration of seedling growth inhibition and Cd accumulation, in comparison with the Cd-stressed alone plants. Total activities and corresponding transcripts of antioxidant enzymes, including superoxide dismutase, peroxidase and ascorbate peroxidase were modulated differentially, thus leading to the alleviation of oxidative damage. Effects of H(2)S above were reversed by 2-(4-carboxyphenyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide potassium salt (cPTIO), the specific scavenger of NO. By using laser confocal scanning microscope combined with Greiss reagent method, further results showed that NO production increased significantly after the NaHS pretreatment regardless of whether Cd was applied or not, all of which were obviously inhibited by cPTIO. These decreases of NO production were consistent with the exaggerated syndromes associated with Cd toxicity. Together, above results suggested that NO was involved in the NaHS-induced alleviation of Cd toxicity in alfalfa seedlings, and also indicated that there exists a cross-talk between H(2)S and NO responsible for the increased abiotic stress tolerance.

“…The accumulation of endogenous H 2 S has become a common response of plants to environmental stress, including salt, heavy metal (HM), drought, heat and cold stress, as well as pathogen infection, which may be closely associated with the acquisition of stress tolerance in plants (Li, 2013; Calderwood and Kopriva, 2014; Hancock and Whiteman, 2014). More interestingly, exogenously applied H 2 S, releasing from its donors such as NaHS and morpholin-4-ium 4-methoxyphenyl(morpholino) phosphinodithioate (GYY4137), shows significant positive effects on seed germination (Li et al, 2012a; Li and He, 2015; Wojtyla et al, 2016), organogenesis and growth (Lin et al, 2012; Fang T. et al, 2014), the regulation of senescence (Zhang et al, 2011), as well as the acquisition of stress tolerance such as salt (Christou et al, 2013), HM (Chen et al, 2013), drought (Christou et al, 2013), heat (Li et al, 2013a,b; Li, 2015c) and cold tolerance (Fu et al, 2013). These results indicate that H 2 S may be a candidate signal molecule in plant cross-adaptation.…”

Hydrogen Sulfide: A Signal Molecule in Plant Cross-Adaptation

For a long time, hydrogen sulfide (H2S) has been considered as merely a toxic by product of cell metabolism, but nowadays is emerging as a novel gaseous signal molecule, which participates in seed germination, plant growth and development, as well as the acquisition of stress tolerance including cross-adaptation in plants. Cross-adaptation, widely existing in nature, is the phenomenon in which plants expose to a moderate stress can induce the resistance to other stresses. The mechanism of cross-adaptation is involved in a complex signal network consisting of many second messengers such as Ca2+, abscisic acid, hydrogen peroxide and nitric oxide, as well as their crosstalk. The cross-adaptation signaling is commonly triggered by moderate environmental stress or exogenous application of signal molecules or their donors, which in turn induces cross-adaptation by enhancing antioxidant system activity, accumulating osmolytes, synthesizing heat shock proteins, as well as maintaining ion and nutrient balance. In this review, based on the current knowledge on H2S and cross-adaptation in plant biology, H2S homeostasis in plant cells under normal growth conditions; H2S signaling triggered by abiotic stress; and H2S-induced cross-adaptation to heavy metal, salt, drought, cold, heat, and flooding stress were summarized, and concluded that H2S might be a candidate signal molecule in plant cross-adaptation. In addition, future research direction also has been proposed.
