title: [Active oxygen species in pea seedlings during the interactions with symbiotic and pathogenic microorganisms].
abstract: The level of active oxygen species (AOS)--superoxide anion radical (O2*-) and hydrogen peroxide (H2O2)--in pea (Pisum sativum L.) cultivar Marat seedlings was studied upon their inoculation with symbiotic (Rhizobium leguminosarum bv. viceae strain CIAM 1026) and pathogenic (Pseudomonas syringae pv. pisi Sackett) microorganisms. Different patterns of the changes in AOS in pea seedlings during the interactions with the symbiont and the phytopathogen were recorded. It is assumed that O2*- and H2O2 are involved in the defense and regulatory mechanisms of the host plant.
