Registration Date 19-01-2026 Organization Plant Breeding and Genetics Institute - National Center of Seed and Cultivar Investigation popup.description1 To determine the role of biochemical indicators (protective proteins, redox components of the signal) in the formation of plant resistance to biotic and abiotic stresses (moisture deficiency, extreme temperatures, fungal and viral diseases), identification of biochemical markers of resistance of major crops (wheat, barley, corn, legumes, sunflower) popup.description2 Our research has shown that damage to cereals plants (wheat, barley, corn), legume crops (soybean, peas, chickpeas) and sunflower by viral (Wheat stripe mosaic virus, Barley yellow dwarf virus, Wheat dwarf virus, Soybean mosaic virus) and fungal diseases(powdery mildew, leaf, stem rusts, septoria leaf blotch et al.), the impact of abiotic stressors (water deficit, hyper-hypothermia) caused, on the one hand, a decrease in yield characteristics, changes in the functioning of the photosynthetic apparatus, and on the other hand, restructuring of cell metabolic processes associated with a violation of oxidative homeostasis, changes in the metabolism of peroxisomes, which participate in reactions that regulate the redox balance of the cell and determine the coupling of processes occurring in different cellular compartments, redox signaling reactions, which leads to further induction of protective mechanisms, in particular components of antioxidant defense, protective proteins. The uneven nature of oxidative homeostasis maintenance due to different activities and features of the isoenzyme composition of antioxidant enzymes and the number of non-enzymatic antioxidants, differences in the level of peroxisome proliferation, features of the generation of signaling mediators, and accumulation and changes in the component composition of protective proteins in wheat and soybean plants, affected by viral and fungal phytopathogens, exposed to abiotic stressors, which depended on the stress factor (phytopathogen, abiotic stressor), the degree of plant damage, and the genotype's resistance to diseases and abiotic stressors has been established. Induction of protective reactions cereals plants using biologically active substances (salicylic and jasmonic acids, lectins, flavonoids) has been shown.
