Stress-induced ethylene production by soybean symbiotic systems depending on genetic characterization of Bradyrhizobium strains.

The production of ethylene by soybeans symbiotic systems associated with different Bradyrhizobium strains during the treatment of seeds with fludioxanil (fungicide) and exposure to drought was studied. It was found that the intensity of ethylene release by soybean plants during pre-sowing fungicide seed treatment and insufficient water supply primarily depends on the genetic characteristics and symbiotic properties of the of Bradyrhizobium strain. It is shown that the treatment of soybean seeds with a fungicide does not significantly change the dynamics of ethylene production by soybean plants in symbiosis with different strains of Bradyrhizobium japonicum under drought conditions. This proves the possibility of using seed inoculation with active rhizobia strains in combination with fungicide treatment for soybean cultivation in arid conditions. [ABSTRACT FROM AUTHOR]
