“…Therefore, any factors that can bring out such changes may offer tolerance to the plants during salinity and other abiotic stress. Some of those factors (priming agents) are phytohormones (Mishra et al, 2020), GABA (Srivastava et al, 2021), trehalose (Mostofa et al, 2015a) NO and H 2 S (Mishra et al, 2021), and so forth.…”

Environmental stresses negatively affect plant development and significantly influence global agricultural productivity. The growth suppression due to soil salinity involves osmotic stress, which is accompanied by ion toxicity, nutritional imbalance, and oxidative stress. The amelioration of salinity stress is one of the fundamental goals to be achieved to ensure food security and better meet the issues related to global hunger. The application of exogenous chemicals is the imperative and efficient choice to alleviate stress in the agricultural field. Among them, hydrogen sulfide (H2S, a gasotransmitter) is known for its efficient role in stress mitigation, including salinity stress, along with other biological features related to growth and development in plants. H2S plays a role in improving photosynthesis and ROS homeostasis, and interacts with other signaling components in a cascade fashion. The current review gives a comprehensive view of the participation of H2S in salinity stress alleviation in plants. Further, its crosstalk with other stress ameliorating signaling component or supplement (e.g., NO, H2O2, melatonin) is also covered and discussed. Finally, we discuss the possible prospects to meet with success in agricultural fields.

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.
