e0“Changes in the concentrations of hydrogen peroxide and cyclic adenosine monophosphate (cAMP) in the roots of seedlings of pea cv. Rondo and its supernodulating mutant Nod3 and anodulating K14 were studied during infection with Rhizobium leguminosarum bv. vicea (strain RCAM 1022) or Pseudomonas syringae pv. pisi (strain 1845)”
e6“It is assumed that hydrogen peroxide and cAMP may be involved in the formation of supernodulating and nodulating phenotypes of mutants”
e7“as well as in the formation of resistance to a specific pathogen, Pseudomonas syringae pv. pisi”

Other claims from this paper (9)
- Intervention effect In Rondo pea seedlings, endogenous hydrogen peroxide level slightly differed from the control 360 min after infection.
- Intervention effect In Nod3 pea roots, hydrogen peroxide level significantly decreased after infection with P. syringae strain 1845.
- Intervention effect In K14 pea roots, hydrogen peroxide level significantly increased after infection with P. syringae strain 1845.
- Intervention effect In K14 pea roots, hydrogen peroxide level remained unchanged after exposure to Rhizobium leguminosarum strain RCAM 1022.
- Intervention effect Strain 1845 had no effect on hydrogen peroxide in young root hairs of Rondo pea seedlings.
- Intervention effect Neither bacterial type changed cAMP concentration in Nod3 pea roots.
- Intervention effect In K14 pea seedlings, RCAM 1022 almost doubled the cAMP level.
- Intervention effect In K14 pea seedlings, strain 1845 decreased the cAMP level.
- Mechanism Hydrogen peroxide and cAMP may be involved in forming the supernodulating and nodulating phenotypes of the mutants.
