“…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 reduced antioxidants/total antioxidants ratio (Li Z.G. et al, 2014), similar results also were found in tobacco cells (Li et al, 2015). In addition, NaHS pretreatment significantly increased the survival percentage of tobacco cells under heat stress and regrowth ability after heat stress, alleviated a decrease in vitality of cells and an increase in electrolyte leakage and MDA accumulation (Li et al, 2012b).…”

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.

“…Similar phenomena were observed in plants. Many external factors, such as damage (Zhang et al 2011 ), hormone induction (Xie et al 2014a ), and lack of light (Hu et al 2015a ; Li et al 2015e ), can lead to early senescence in plants. Besides, rhythm, climate and seasonal changes also induce the natural aging of plants.…”

“…For example, H 2 S treatment alleviated dark-promoted senescence in broccoli florets by sustaining higher activities of GPX, APX, CAT and GR and lower activities of lipoxygenase (LOX), PPO, PAL and protease (Li et al 2014b , 2015e ). Similarly, NaHS treatment on aleurone tissue led to higher transcript levels of the antioxidant genes HvSOD1 , HvAPX , HvCAT1 and HvCAT2 and lower transcript levels of HvLOX and cysteine protease genes HvEPA and HvCP3-31 (Zhang et al 2015a ).…”

Hydrogen sulfide (H 2 S) was initially recognized as a toxic gas and its biological functions in mammalian cells have been gradually discovered during the past decades. In the latest decade, numerous studies have revealed that H 2 S has versatile functions in plants as well. In this review, we summarize H 2 S-mediated sulfur metabolic pathways, as well as the progress in the recognition of its biological functions in plant growth and development, particularly its physiological functions in biotic and abiotic stress responses. Besides direct chemical reactions, nitric oxide (NO) and hydrogen peroxide (H 2 O 2 ) have complex relationships with H 2 S in plant signaling, both of which mediate protein post-translational modification (PTM) to attack the cysteine residues. We also discuss recent progress in the research on the three types of PTMs and their biological functions in plants. Finally, we propose the relevant issues that need to be addressed in the future research.

“…All of these increases induced by Ca 2+ /CaM, in DES1 activity, H 2 S content, and heat tolerance are enhanced by the H 2 S donor NaHS or weakened by H 2 S synthesis inhibitors or an H 2 S scavenger. Therefore, during the heat stress response process, the H 2 S and Ca 2+ signals may be interdependent [ 112 ].…”

Hydrogen sulfide (H2S), once recognized only as a poisonous gas, is now considered the third endogenous gaseous transmitter, along with nitric oxide (NO) and carbon monoxide (CO). Multiple lines of emerging evidence suggest that H2S plays positive roles in plant growth and development when at appropriate concentrations, including seed germination, root development, photosynthesis, stomatal movement, and organ abscission under both normal and stress conditions. H2S influences these processes by altering gene expression and enzyme activities, as well as regulating the contents of some secondary metabolites. In its regulatory roles, H2S always interacts with either plant hormones, other gasotransmitters, or ionic signals, such as abscisic acid (ABA), ethylene, auxin, CO, NO, and Ca2+. Remarkably, H2S also contributes to the post-translational modification of proteins to affect protein activities, structures, and sub-cellular localization. Here, we review the functions of H2S at different stages of plant development, focusing on the S-sulfhydration of proteins mediated by H2S and the crosstalk between H2S and other signaling molecules.
