“…Research has shown that the synthesis of these metabolites or external application to plants can reduce the stress level [32]. At the molecular level, upon perceiving salt stress, specific genes are activated or repressed, leading to the synthesis of stress-responsive proteins, which play a vital role in protecting plants against the harmful effects of salt stress [33]. One of the key transcription factors involved in the response to salt stress is DREB1A.…”

Due to being sessile, plants develop a broad range of defense pathways when they face abiotic or biotic stress factors. Although plants are subjected to more than one type of stress at a time in nature, the combined effects of either multiple stresses of one kind (abiotic or biotic) or more kinds (abiotic and biotic) have now been realized in agricultural lands due to increases in global warming and environmental pollution, along with population increases. Soil-borne pathogens, or pathogens infecting aerial parts, can have devastating effects on plants when combined with other stressors. Obtaining yields or crops from sensitive or moderately resistant plants could be impossible, and it could be very difficult from resistant plants. The mechanisms of combined stress in many plants have previously been studied and elucidated. Recent studies proposed new defense pathways and mechanisms through signaling cascades. In light of these mechanisms, it is now time to develop appropriate strategies for crop protection under multiple stress conditions. This may involve using disease-resistant or stress-tolerant plant varieties, implementing proper irrigation and drainage practices, and improving soil quality. However, generation of both stress-tolerant and disease-resistant crop plants is of crucial importance. The establishment of a database and understanding of the defense mechanisms under combined stress conditions would be meaningful for the development of resistant and tolerant plants. It is clear that leaf pathogens show great tolerance to salinity stress and result in pathogenicity in crop plants. We noticed that regulation of the stomata through biochemical applications and some effort with the upregulation of the minor gene expressions indirectly involved with the defense mechanisms could be a great way to increase the defense metabolites without interfering with quality parameters. In this review, we selected wheat as a model plant and Zymoseptoria tritici as a model leaf pathogen to evaluate the defense mechanisms under saline conditions through physiological, biochemical, and molecular pathways and suggested various ways to generate tolerant and resistant cereal plants.

Plant glutathione peroxidases (GPXs) consist of non-heme thiol peroxidases that are vital in maintaining hydrogen peroxide homeostasis and regulating plant environmental stress responses. A comparative genomic analysis of the GPX gene family in Ipomoea trifida and I. triloba using their respective genomes was performed. Six GPX genes were identified in each species, which were unevenly located in 4 of the 15 chromosomes of the closest ancestors of the sweet potato genomes (I. trifida and I. triloba). The presence of gene duplications and positive selection were highlighted, suggesting the evolutionary significance of the GPX genes in these species. Based on the phylogenetic analysis, the GPX genes of I. trifida, I. triloba, Arabidopsis thaliana and Oryza sativa can be classified into four groups (I, II, III and IV). The in silico expression analysis in different tissues and development stages revealed tissue-specific expression patterns, hinting at specialized roles for the GPX genes in different plant organs. Nonetheless, the ItfGPX5 and ItbGPX5 genes were highly expressed in most the studied tissues.
