“…This is particularly true for S as drought stress results in low SO 4 2− absorption and its subsequent translocation to leaves that also limits NO 3 − translocation, consequently reducing nitrogen use efficiency 39 . Similarly, S-deprivation influences K accumulation in shoots providing evidence that K + acts as counter-cation in the absence of SO 4 2− in leaf tissue 24,40 .

Restriction in nutrient acquisition is one of the primary causes for reduced growth and yield in water deficient soils. Sulfur (S) is an important secondary macronutrient that interacts with several stress metabolites to improve performance of food crops under various environmental stresses including drought. Increased S supply influences uptake and distribution of essential nutrients to confer nutritional homeostasis in plants exposed to limited water conditions. The regulation of S metabolism in plants, resulting in synthesis of numerous S-containing compounds, is crucial to the acclimation response to drought stress. Two different experiments were laid out in semi-controlled conditions to investigate the effects of different S sources on physiological and biochemical mechanisms of maize (Zea mays L. cv. P1574). Initially, the rate of S application in maize was optimized in terms of improved biomass and nutrient uptake. The maize seedlings were grown in sandy loam soil fertigated with various doses (0, 15, 30 and 45 kg ha −1) of different S fertilizers viz. K 2 So 4 , feSo 4 , cuSo 4 and na 2 So 4. The optimized S dose of each fertilizer was later tested in second experiment to determine its role in improving drought tolerance of maize plants. A marked effect of S fertilization was observed on biomass accumulation and nutrients uptake in maize. In addition, the optimized doses significantly increased the gas exchange characteristics and activity of antioxidant enzymes to improve yield of maize. Among various S sources, application of K 2 So 4 resulted in maximum photosynthetic rate (43%), stomatal conductance (98%), transpiration rate (61%) and sub-stomatal conductance (127%) compared to no S supply. Moreover, it also increased catalase, guaiacol peroxidase and superoxide dismutase activities by 55, 87 and 65%, respectively that ultimately improved maize yield by 33% with respect to control under water deficit conditions. These results highlight the importance of S fertilizers that would likely be helpful for farmers to get better yield in water deficient soils. Maize (Zea mays L.) is one of the major cereal crops that provide food for humans and feed for livestock. The demand for maize seed has increased significantly during past few decades due to its consumption in poultry feed and wet milling industry. The importance of maize as a food crop is well recognized and is used as a staple food in many parts of the world 1. Maize seed is an abundant source of energy as 100 g seed provides 365 kilocalories of energy 2. However, it is an extensive nutrient crop and excessive use of fertilizers to obtain high yield has resulted in the depletion of nutrients particularly sulfur (S) in soils 3. Moreover, water shortage due to climate change may induce further losses in maize production in future. Adaptation of maize to limited water conditions has received great interest from farmers, researchers and policy makers considering its importance in nutritional food security. Since maize requires large quantities of water to...

Plants often face a variety of abiotic stresses, which affects them negatively and lead to yield loss. The antioxidant system efficiently removes excessive reactive oxygen species and maintains redox homeostasis in plants. With better understanding of these protective mechanisms, recently the concept of hydrogen sulfide (H2S) and its role in cell signaling has become the center of attention. H2S has been recognized as a third gasotransmitter and a potent regulator of growth and development processes such as germination, maturation, senescence and defense mechanism in plants. Because of its gaseous nature, H2S can diffuse to different part of the cells and balance the antioxidant pools by supplying sulfur to cells. H2S showed tolerance against a plethora of adverse environmental conditions like drought, salt, high temperature, cold, heavy metals and flood via changing in level of osmolytes, malonaldialdehyde, Na+/K+ uptake, activities of H2S biosynthesis and antioxidative enzymes. It also promotes cross adaptation through persulfidation. H2S along with calcium, methylglyoxal and nitric oxide, and their cross talk induces the expression of mitogen activated protein kinases as well as other genes in response to stress. Therefore, it is sensible to evaluate and explore the stress responsive genes involved in H2S regulated homeostasis and stress tolerance. The current article is aimed to summarize the recent updates on H2S‐mediated gene regulation in special reference to abiotic stress tolerance mechanism, and cross adaptation in plants. Moreover, new insights into the H2S‐associated signal transduction pathway have also been explored.

“…Li et al (, b) reported that H 2 S functions not only downstream of NO signaling, but also acts downstream of salicylic acid‐induced heat tolerance signaling pathways (Li et al ). Post‐harvest ripening and senescence in banana could be alleviated by H 2 S by countering oxidative stress along with the antagonizing effect of ethylene signaling (Ge et al , Hasanuzzaman et al ). On the other hand, H 2 S was found to act upstream of NADPH oxidase (RBOH1) and H 2 O 2 accumulation, governing the tomato root morphogenesis (Mei et al ).…”

Plants are exposed to a plethora of abiotic stresses such as drought, salinity, heavy metal and temperature stresses at different stages of their life cycle, from germination to seedling till the reproductive phase. As protective mechanisms, plants release signaling molecules that initiate a cascade of stress‐signaling events, leading either to programmed cell death or plant acclimation. Hydrogen sulfide (H2S) and nitric oxide (NO) are considered as new ‘gasotransmitter’ molecules that play key roles in regulating gene expression, posttranslational modification (PTM), as well as cross‐talk with other hormones. Although the exact role of NO in plants remains unclear and is species dependent, various studies have suggested a positive correlation between NO accumulation and environmental stress in plants. These molecules are also involved in a large array of stress responses and act synergistically or antagonistically as signaling components, depending on their respective concentration. This study provides a comprehensive update on the signaling interplay between H2S and NO in the regulation of various physiological processes under multiple abiotic stresses, modes of action and effects of exogenous application of these two molecules under drought, salt, heat and heavy metal stresses. However, the complete picture of the signaling cascades mediated by H2S and NO is still elusive. Recent researches indicate that during certain plant processes, such as stomatal closure, H2S could act upstream of NO signaling or downstream of NO in response to abiotic stresses by improving antioxidant activity in most plant species. In addition, PTMs of antioxidative pathways by these two molecules are also discussed.
