“…The KEGG pathway enrichment analysis showed that MT could enhance the zeatin biosynthesis pathway ( Figure 3 D). Cytokinin is considered associated with plant development and salt stress response [ 86 , 87 , 88 , 89 ]. In grape berries and kiwifruits, the flavonoid content was increased after melatonin treatment and the related genes involved in flavonoids and anthocyanins were significantly up-regulated [ 90 , 91 ].…”

Melatonin (MT) can effectively reduce oxidative damage induced by abiotic stresses such as salt in plants. However, the effects of MT on physiological responses and molecular regulation during wheat germination remains largely elusive. In this study, the response of wheat seeds to MT under salt stress during germination was investigated at physiological and transcriptome levels. Our results revealed that application of MT significantly reduced the negative influence of salt stress on wheat seed germination. The oxidative load was reduced by inducing high activities of antioxidant enzymes. In parallel, the content of gibberellin A3 (GA3) and jasmonic acid (JA) increased in MT-treated seedling. RNA-seq analysis demonstrated that MT alters oxidoreductase activity and phytohormone-dependent signal transduction pathways under salt stress. Weighted correlation network analysis (WGCNA) revealed that MT participates in enhanced energy metabolism and protected seeds via maintained cell morphology under salt stress during wheat seed germination. Our findings provide a conceptual basis of the MT-mediated regulatory mechanism in plant adaptation to salt stress, and identify the potential candidate genes for salt-tolerant wheat molecular breeding.

“…Cytokinins (CKs) are plant hormones that are highly involved in the regulation of plant growth and development, but also in stress responses. Published data suggest that the role of CKs in salt stress can be contradictory and depends on plant species, applied salt concentration, and plant growth stage [63]. Reduced growth under salt stress is also associated with reduced gibberellic acid GA levels in plants [64].…”

Beneficial Microbes and Molecules for Mitigation of Soil Salinity in Brassica Species: A Review

Salt stress results from excessive salt accumulation in the soil can lead to a reduction in plant growth and yield. Due to climate change, in the future climatic pressures, changed precipitation cycles and increased temperature will increase the pressures on agriculture, including increasing severity of salt stress. Brassica species contains oilseed and vegetable crops with great economic importance. Advances in understanding the mechanisms of salt stress in Brassica plants have enabled the development of approaches to better induce plant defense mechanisms at the time of their occurrence through the use of beneficial microorganisms or molecules. Both endophytic and rhizospheric microbes contribute to the mitigation of abiotic stresses in Brassica plants by promoting the growth of their host under stress conditions. In this review we summarized so far reported microorganisms with beneficial effects on Brassica plants and their mode of action. Another approach in mitigating the harmful effect of soil salinity may involve the application of different molecules that are involved in the stress response of Brassica plants. We reviewed and summarized their potential mode of action, methods of application and pointed out further research directions.

“…Cytokinins (CKs) are also important plant hormones involved in cell growth and development and biosynthesis of chloroplast (Yu et al, 2021). CKs are major regulators in enhancing the defense system and protecting oxidase damage under salinity stress (Atanasova et al, 1996).…”

Salinity is considered a global threat to agriculture and causes a significant reduction in crop yield. In particular, salinity stress promotes reactive oxygen species (ROS) accumulation and ionic imbalance in cells, leading to oxidative stress and even cell death. A large number of genes which are involved in defense, hormone, carbohydrate and metabolic pathways are down-regulated under salinity stress. Plants respond to salinity stress through a series of physiological and molecular mechanisms including antioxidant enzymes, hormones, defense related genes and signaling pathway activation. Plant defense systems modulate the overproduction of ROS through the activation of stress responsive-genes such as superoxide dismutase (SOD), peroxidase (POD), catalase (CAT) and glutamine synthetase (GS) and transcription factors such as MYBs, WRKY, and ERF. The salt overly sensitive (SOS) pathway is potentially involved in salt stress tolerance. SOS1, SOS3 and SOS2 are required for the oxidative stress tolerance by reducing the uptakes, and inter-cellular and intra-cellular distribution of Na+ and Cl−. This review discusses the discovery of stress-responsive genes and signaling pathways, and summarizes the research progress on the regulatory mechanisms of salinity stress tolerance in plants, which will help accelerate breeding programs for salinity stress tolerance.
