The staff of the Laboratory of Molecular and Cellular Biology under the guidance of Anna Viktorovna Tsyganova in collaboration with Prof. Nicholas Bruin (Distinguished Fellow of the John Innes Center, Great Britain) published in the Journal of Plants the results of many years of research on the dynamics of localization of hydrogen peroxide in various zones of pea nodules. Several genotypes of peas were used in the work, as well as mutants blocked at various stages of symbiosis development. The results obtained are in good agreement with the previously proposed role of nepokcuga hydrogen in the growth of infectious filaments through its association with an increase in the stiffness of the wall of the infectious filament. The role of hydrogen peroxide in the maturation of the cell wall of infected cells during their differentiation has also been proposed. The revealed intensive accumulation of hydrogen peroxide in the nodules of symbiotic mutants of peas reflects the activation of protective reactions and oxidative stress during the development of ineffective symbiosis. The research was supported by the RNF grant 23-16-00090.
