Dynamics of Hydrogen Peroxide Accumulation During Tip Growth of Infection Thread in Nodules and Cell Differentiation in Pea (<i>Pisum sativum</i> L.) Symbiotic Nodules.

ABSTRACT: Hydrogen peroxide (H₂O₂) in plants is produced in relatively large amounts and plays a universal role in plant defense and physiological responses, including the regulation of growth and development. In the Rhizobium-legume symbiosis, hydrogen peroxide plays an important signaling role throughout the development of this interaction. In the functioning nodule, H₂O₂ has been shown to be involved in bacterial differentiation into the symbiotic form and in nodule senescence. In this study, the pattern of H₂O₂ accumulation in pea (Pisum sativum L.) wild-type and mutant nodules blocked at different stages of the infection process was analyzed using a cytochemical reaction with cerium chloride. The observed dynamics o
