[Hydrogen peroxide content and catalase activity at inoculation with root tubercle bacteria of pea seedlings with the various nodulation ability].
Hydrogen peroxide (H2O2) content and catalase activity were studied in pea (Pisum sativum L.) seedlings with normal (cultivar Marat) and disrupted (pea mutants) process of nodulation, which were inoculated with the nitrogen-fixing bacterium Rhizobium leguminosarum strain CIAM 1026. Differences in hydrogen peroxide content and catalase activity in pea seedlings with different ability for nodulation, which were inoculated with rhizobia, were found. It was assumed that H2O2 and catalase are involved in defensive and regulatory mechanisms in the host plant.
