Registration Date 14-01-2025 Organization Institute of Plant Physiology and Genetics of the National Academy of Sciences of Ukraine popup.description1 Investigation of physiological-biochemical and molecular-genetic features of formation and functioning of symbiotic systems of soybean and alfalfa with nodule bacteria under the action of biotic and abiotic external factors in order to create effective plant-microbial complexes to increase the productivity of legumes. popup.description2 Compounds with growth-regulating properties in low concentrations - methyl jasmonate (0.0075 mM) and salicylic acid (0.05 mM) can be used as additional components of Bradyrhizobium japonicum B1-20 culture medium to stimulate the growth of bacterial biomass, the use of which for the treatment of soybean seeds in vegetative and field conditions leads to an increase in the process of nitrogen fixation and seed productivity of soybeans. The use of salicylic acid (50 μM) or methyl jasmonate (0.75 μM) as components of the culture medium for rhizobia of the highly virulent strain 604k induces intensification of catalase activity in soybean roots in the early stages of ineffective symbiosis formation. The addition of salicylic acid (50 μM) to the culture medium of effective virulent rhizobia (Tn5 mutant B1-20) initiates the activation of the catalase enzyme complex, while the use of methyl jasmonate (0.75 μM) does not affect the activity of the enzyme in soybean roots during the formation of effective symbiotic systems.
