“…Recent studies have shown that, in plant systems, the application of exogenous H 2 S donors can significantly enhance the tolerance of plants to abiotic stresses, such as drought, high salinity, and toxic heavy metals [ 45 , 60 , 61 ]. More and more attention has been paid to the mechanism by which the signaling molecule H 2 S in the plant system regulates other signaling pathways involved in various abiotic stress responses [ 62 ]. It had been reported that H 2 S could improve drought tolerance in rice by re-establishing redox homeostasis and activating the ABA signaling pathway [ 63 ], and could also alleviate aluminum toxicity by reducing aluminum content in rice [ 64 ].…”

Soil salinity severely threatens plant growth and crop performance. Hydrogen sulfide (H2S), a plant signal molecule, has been implicated in the regulation of plant responses to salinity stress. However, it is unclear how the transcriptional network regulates H2S biosynthesis during salt stress response. In this study, we identify a rice NAC (NAM, ATAF and CUC) transcription factor, OsNAC35-like (OsNACL35), from a salt-tolerant cultivar ‘Sea Rice 86′ (SR86) and further show that it may have improved salt tolerance via enhanced H2S production. The expression of OsNACL35 was significantly upregulated by high salinity and hydrogen peroxide (H2O2). The OsNACL35 protein was localized predominantly in the nucleus and was found to have transactivation activity in yeast. The overexpression of OsNACL35 (OsNACL35-OE) in japonica cultivar Nipponbare ramatically increased resistance to salinity stress, whereas its dominant-negative constructs (SUPERMAN repression domain, SRDX) conferred hypersensitivity to salt stress in the transgenic lines at the vegetative stage. Moreover, the quantitative real-time PCR analysis showed that many stress-associated genes were differentially expressed in the OsNACL35-OE and OsNACL35-SRDX lines. Interestingly, the ectopic expression of OsNACL35 triggered a sharp increase in H2S content by upregulating the expression of a H2S biosynthetic gene, OsDCD1, upon salinity stress. Furthermore, the dual luciferase and yeast one-hybrid assays indicated that OsNACL35 directly upregulated the expression of OsDCD1 by binding to the promoter sequence of OsDCD1. Taken together, our observations illustrate that OsNACL35 acts as a positive regulator that links H2S production to salt stress tolerance, which may hold promising utility in breeding salt-tolerant rice cultivar.

“…At present, the pathway of NO modulating the crosstalk between ABA and H 2 O 2 and activating the calcium signaling pathway has also been further revealed [ 31 ]. Wang et al mentioned that extracellular Ca 2+ and ABA promote stomatal closure by promoting H 2 O 2 to produce calcium signals dependent on NO synthesis [ 32 ]. In Arabidopsis ABI mutants, H 2 O 2 and NO activate calcium signals depending on cyclic guanosine 3′,5′-monophosphate (cGMP), which likely acts upstream of calcium signals.…”

Plants have evolved many strategies for adaptation to extreme environments. Ca2+, acting as an important secondary messenger in plant cells, is a signaling molecule involved in plants’ response and adaptation to external stress. In plant cells, almost all kinds of abiotic stresses are able to raise cytosolic Ca2+ levels, and the spatiotemporal distribution of this molecule in distant cells suggests that Ca2+ may be a universal signal regulating different kinds of abiotic stress. Ca2+ is used to sense and transduce various stress signals through its downstream calcium-binding proteins, thereby inducing a series of biochemical reactions to adapt to or resist various stresses. This review summarizes the roles and molecular mechanisms of cytosolic Ca2+ in response to abiotic stresses such as drought, high salinity, ultraviolet light, heavy metals, waterlogging, extreme temperature and wounding. Furthermore, we focused on the crosstalk between Ca2+ and other signaling molecules in plants suffering from extreme environmental stress.

Hydrogen sulphide‐mediated alleviation and its interplay with other signalling molecules during temperature stress

The sessile habit of plants does not provide choices to escape the environmental constraints, leading to negative impacts on their growth and development. This causes significant losses in the agriculture sector and raises serious issues on global food security. Extreme temperatures (high or low) influence several aspects of plant life and can cause reproduction malfunction. Therefore, a strategy for temperature amelioration is necessary for the management of agricultural productivity. Supplementation with various chemicals (e.g. phytohormones, gasotransmitters, osmolytes) is considered a good choice to manage plant stress. Gasotransmitters are well‐recognized for stress mitigation in plants, among which hydrogen sulphide (H2S) has proved promising to alleviate stress. Temperature (heat/cold) stress can stimulate the endogenous production of H2S in plants, and many studies have reported the significance of H2S for temperature stress amelioration. Here, H2S led to positive changes in plant physiological, biochemical and molecular responses, which are usually compromised during stress. Further, H2S also coordinate with other signalling components that act either upstream or downstream during stress mitigation. This review focuses on the significance of H2S for mitigation of temperature stress, with a comprehensive discussion on cross‐talk with other signalling components or supplements (e.g. NO, H2O2, salicylic acid, trehalose, proline). Finally, the review provides a rational assessment and holistic understanding of H2S‐mediated mitigation of extreme temperature stress and addresses the prospects for development of an effective strategy to manage temperature stress.
