Abstract
The dynamics of changes in activities of the enzymes pyruvate kinase (PK-ase, EC 2.7.1.40), NAD-malate dehydrogenase (NAD-MDH, EC 1.1.1.37), and oxaloacetate decarboxylase (OAD-ase, EC 4.1.1.3) have been studied in the initial development phases of the common bean (Phaseolus vulgaris L.) plant leaves exposed to the combined effect of various radiation doses (5, 10, 50 Gy) and salt concentrations (1, 5, 10, 50 mM NaCl). It has been found that the combined effect of radiation (50 Gy) and salt (10-50 mM NaCl) causes a more active stimulating effect on common bean plants. At the intersection of energy exchange pathways, this effect forms inductive mechanisms that connect these pathways with substrates and intermediate metabolites and coordinate their functions mainly at the level of intermediate metabolites, proteins, pigments, activities of PK-ase, NAD-MDH, OAD-ase, and the H+-pump. Inductive mechanisms arising under stress conditions cause temporary or permanent adaptive traits in the common bean plant.
