[Oxidation processes at initial stages of interaction of root nodule bacteria (Rhizobium leguminosarum) and pea (Pisum sativum L.): a review].

A possible physiological mechanism of legume-Rhizobium symbiosis, consisting in regulation of the intensity of oxidation processes by the microsymbiont in response to infection with Rhizobium, was analyzed using our own and published data. The results used in the analysis included data on the content of reactive oxygen species (O2*-, and H2O2), activity of antioxidant enzymes (superoxide dismutase, catalase, and peroxidase), and intensity of lipid peroxidation proceeding with the involvement of lipophilic phenolic compounds of the microsymbiont.
