In the past decade, hydrogen sulfide (H 2 S) and nitric oxide (NO) have emerged as major signaling molecules which are involved in most life cycle processes in plants, i.e. from seed germination to plant death. H 2 S and NOregulated development of plants requires integration of complex signaling networks and also involves other signaling pathways. Moreover, to re-establish cellular redox homeostasis under stress conditions, regulation of gene expression takes place, which helps in achieving an appropriate plant response. In this context, the most significant controls occur at the transcriptional, posttranscriptional and post-translational levels which help in acquiring adaptive changes in stress-challenged plants. Although various studies have demonstrated the role of H 2 S and NO in regulating a plethora of plant growth and development processes under stressed/nonstressed conditions, much remains to be elucidated regarding their roles in plant biology. Therefore, this special issue was organized to collect state-of-the-art plant research involving H 2 S and NO under changing environmental conditions. This special issue has collected seven reviews and 11 original research articles aimed at compiling a comprehensive status quo on the implication of H 2 S and NO signaling in plant biology.Review articles herein provide an up-to-date coverage of existing progress in this continuously growing research area. Prakash et al. (2019) have examined the role of NO and ROS (reactive oxygen species) in governing root system architecture in plants. Rai et al. (2019) have given an overview of NO and salicylic acid signaling towards acquired heat tolerance in plants. Paul and Roychoudhury (2019), Pandey and Gautam (2019) and Singh et al. (2019) have covered exhaustive current roles of H 2 S and NO in plants under changing environmental conditions. Finally, Sharma et al. (2019) and Shivaraj et al. (2019) have discussed molecular mechanisms and crosstalk of NO and H 2 S in metal stress tolerance. Research articles have covered diverse new roles of H 2 S and NO in regulating abiotic stress in plants. Kushwaha and Singh (2019) and Ahmad et al. (2019) have reported various mechanisms through which H 2 S regulates chromium toxicity in crop plants. Regulatory roles of NO and H 2 S were reported for salt and drought stress, as well as iron deficiency in plants (Batista et al. 2019, Gohari et al. 2019, Jahan et al. 2019, Kaya et al. 2019a). The role of NO and H 2 S along with that of Si was evaluated for the regulation of cadmium stress in plants (Kaya et al. 2019b). Muñoz-Vargas et al. (2019) have noticed inhibition of NADP-malic enzyme activity by H 2 S and NO in sweet pepper. Furthermore, the role of H 2 S was examined in regulating photosynthesis under overnight frost and daytime high light in avocado (Joshi et al. 2019). Finally, Kataria et al. (2019) have reported crucial role of nitrate reductase-dependent production of NO in regulating magnetopriming-induced salt tolerance in soybean.All together, this collection of articles pres...

“…Further NO was seen to affect major metabolic pathways in plants, particularly of nutrient assimilation. Our recent research on NO suggests that salt stress effects on the photosynthetic performance are mitigated effectively when NO was applied along with the split application of both N and S, and the photosynthetic activity was stimulated through increased N and S assimilation and antioxidant system conferring tolerance against salt stress (Jahan et al, 2020). Similarly.…”

Phytotoxicity of metals significantly contributes to the major loss in agricultural productivity. Among all the metals, copper (Cu) is one of essential metals, where it exhibits toxicity only at its supra-optimal level. Elevated Cu levels affect plants developmental processes from initiation of seed germination to the senescence, photosynthetic functions, growth and productivity. The use of plant growth regulators/phytohormones and other signaling molecules is one of major approaches for reversing Cu-toxicity in plants. Nitric oxide (NO) is a versatile and bioactive gaseous signaling molecule, involved in major physiological and molecular processes in plants. NO modulates responses of plants grown under optimal conditions or to multiple stress factors including elevated Cu levels. The available literature in this context is centered mainly on the role of NO in combating Cu stress with partial discussion on underlying mechanisms. Considering the recent reports, this paper: (a) overviews Cu uptake and transport; (b) highlights the major aspects of Cu-toxicity on germination, photosynthesis, growth, phenotypic changes and nutrient-use-efficiency; (c) updates on NO as a major signaling molecule; and (d) critically appraises the Cu-significance and mechanisms underlying NO-mediated alleviation of Cu-phytotoxicity. The outcome of the discussion may provide important clues for future research on NO-mediated mitigation of Cu-phytotoxicity.

“…It causes losses of about USD 27.5 billion and affects an area of approximately 936 Mha yearly nationwide [ 3 , 4 ]. Salt stress induces different physio-biochemical abnormalities, toxic ion uptake as sodium (Na + ) and chloride (Cl − ),imbalances of essential nutrients, and dual hyperosmotic effects and disturbs the homeostasis of water, reducing plant growth rates and yield productivity [ 5 , 6 ]. Additionally, salt stress damages cellular membranes through reactive oxygen species (ROS) accumulation.…”

“…To lessen the damaging effects of salt stress, plants have developed several processes that involve antioxidant defense systems, compartmentation of ions, and osmolyte accumulation [ 5 , 6 ]. The enhancement of antioxidant enzymes works as an observable defense strategy under stress that interacts with ROS detoxification [ 5 , 8 , 11 ].…”

In the present study, the potential of ethylene as ethephon (an ethylene source) was investigated individually and in combination with split doses of nitrogen (N) and sulfur (S) soil treatments for removal of the damaging effects of salt stress (100 mM NaCl) in mustard (Brassica juncea L.). Plants were grown with 50 mg N plus 50 mg S kg−1 soil at sowing time and an equivalent dose at 20 days after sowing [N50 + S50]0d and 20d. Ethephon at 200 μL L‒1 was applied to combined split doses of N and S with or without NaCl. Plants subjected to NaCl showed a decrease in growth and photosynthetic characteristics as well as N and S assimilation, whereas proline metabolism and antioxidants increased. The application of ethephon to plants grown with split N and S doses significantly enhanced photosynthetic efficiency by increasing the assimilation of N and S, improving the concentration of proline and induction of the antioxidant system with or without NaCl. The regulation of ethylene and/or split forms of N and S application may be potential tools for not just overcoming salt stress effects in this species and in related Brassicaceae but also enhancing their photosynthesis and growth potential through increased nutrient assimilation.
