“…Jasmonic acid (JA) and methyl jasmonate (MJ) also impart salt tolerance in plants by reducing the concentration of Na + ions (Kang et al, 2005). SA and MJ imparted salt tolerance in strawberry by inducing changes in the antioxidant activity, Na + /K + ratio, and proline content (Faghih et al, 2019). Humic acid (HA) was reported to improve salinity tolerance in foxtail millet (Biswas et al, 2019).…”

The agriculture sector is vulnerable to various environmental stresses, which significantly affect plant growth, performance, and development. Abiotic stresses, such as salinity and drought, cause severe losses in crop productivity worldwide. Soil salinity is a major stress suppressing plant development through osmotic stress accompanied by ion toxicity, nutritional imbalance, and oxidative stress. Various defense mechanisms like osmolytes accumulations, activation of stress‐induced genes, and transcription factors, production of plant growth hormones, accumulation of antioxidants, and redox defense system in plants are responsible for combating salt stress. Nitric oxide (NO) and hydrogen sulphide (H2S) have emerged as novel bioactive gaseous signaling molecules that positively impact seed germination, homeostasis, plant metabolism, growth, and development, and are involved in several plant acclimation responses to impart stress tolerance in plants. NO and H2S trigger cell signaling by activating a cascade of biochemical events that result in plant tolerance to environmental stresses. NO‐ and H2S‐mediated signaling networks, interactions, and crosstalks facilitate stress tolerance in plants. Research on the roles and mechanisms of NO and H2S as challengers of salinity is entering an exponential exploration era. The present review focuses on the current knowledge of the mechanisms of stress tolerance in plants and the role of NO and H2S in adaptive plant responses to salt stress and provides an overview of the signaling mechanisms and interplay of NO and H2S in the regulation of growth and development as well as modulation of defense responses in plants and their long term priming effects for imparting salinity tolerance in plants.

“…Saline stress is mainly caused by neutral salt, while alkaline stress is mainly caused by alkaline salt [ 9 ]; saline stress generally causes ionic damage and osmotic stress in plants [ 10 ], and alkaline stress not only causes the above-mentioned damage to plants, but also increases the pH in plants [ 11 ]. Previous studies have found that the application of exogenous materials is one of the effective ways to regulate the responses of crops to saline stress and alkaline stress [ 12 , 13 ]. Chemical modification can be used to regulate the responses of crops to saline stress and alkaline stress through replacing Na + in soil by applying inorganic salts (e.g.…”

“…Gong, et al [ 12 ] found that melatonin regulated the enzyme activity and biosynthesis of polyamines and improved the tolerance of plants to alkaline stress. Faghih, et al [ 13 ] showed that spraying salicylic acid and methyl jasmonate on the leaves could improve the defense system and antioxidant capacity of strawberry under salt stress. Therefore, it is of great importance to study the effects of the application of exogenous materials on the responses of plants to saline stress and alkaline stress.…”

Background Soil salinization and alkalinization are the main factors that affect the agricultural productivity. Evaluating the persistence of the compound material applied in field soils is an important part of the regulation of the responses of cotton to saline and alkaline stresses. Result To determine the molecular effects of compound material on the cotton’s responses to saline stress and alkaline stress, cotton was planted in the salinized soil (NaCl 8 g kg− 1) and alkalized soil (Na2CO3 8 g kg− 1) after application of the compound material, and ion content, physiological characteristics, and transcription of new cotton leaves at flowering and boll-forming stage were analyzed. The results showed that compared with saline stress, alkaline stress increased the contents of Na+, K+, SOD, and MDA in leaves. The application of the compound material reduced the content of Na+ but increased the K+/Na+ ratio, the activities of SOD, POD, and CAT, and REC. Transcriptome analysis revealed that after the application of the compound material, the Na+/H+ exchanger gene in cotton leaves was down-regulated, while the K+ transporter, K+ channel, and POD genes were up-regulated. Besides, the down-regulation of genes related to lignin synthesis in phenylalanine biosynthesis pathway had a close relationship with the ion content and physiological characteristics in leaves. The quantitative analysis with PCR proved the reliability of the results of RNA sequencing. Conclusion These findings suggest that the compound material alleviated saline stress and alkaline stress on cotton leaves by regulating candidate genes in key biological pathways, which improves our understanding of the molecular mechanism of the compound material regulating the responses of cotton to saline stress and alkaline stress.

Background: Soil salinization and alkalinization are the main factors that affect the agricultural productivity. Evaluating the persistence of the compound material applied in field soils is an important part of the regulation of the responses of cotton to saline and alkaline stresses. Result: To determine the molecular effects of compound material on the cotton’s responses to saline stress and alkaline stress, cotton was planted in the salinized soil (NaCl 8g kg -1 ) and alkalized soil (Na 2 CO 3 8g kg -1 ) after application of the compound material, and ion content, physiological characteristics, and transcription of new cotton leaves at flowering and boll-forming stage were analyzed. The results showed that compared with saline stress, alkaline stress increased the contents of Na + , K + , SOD, and MDA in leaves. The application of the compound material reduced the content of Na + but increased the K + /Na + ratio , the activities of SOD, POD, and CAT, and REC. Transcriptome analysis revealed that after the application of the compound material, the Na + /H + exchanger gene in cotton leaves was down-regulated, while the K + transporter, K + channel, and POD genes were up-regulated. Besides, the down-regulation of genes related to lignin synthesis in phenylalanine biosynthesis pathway had a close relationship with the ion content and physiological characteristics in leaves.
