title: [Hypoxic stress and the transport systems of the peribacteroid membrane of bean root nodules].
abstract: When the roots of Vicia faba L. beans were subjected to hypoxic stress, the activity of H(+)-ATPase on the peribacteroid membrane, as well as the transport of dicarboxylates (malate and succinate) mediated by this enzyme, decreased. Since malate and succinate are the main carbon-containing metabolites involved in the energy supply to bacteroids, this caused a change of the relation type from mutualism to commensalism, and the domination of the eukaryote over the prokaryote consequently increased.
