Influence of the processing of seeds with gamma rays before sowing on the activity of CO₂ metabolism enzymes in some plants

In natural medium, it has been comparatively studied the activities of the enzymes of carboanhydrase (CA, CF 4.2.1.1), phosphoenolpyruvate carboxylase (PEPC, CF 4.1.1.31) and ribulose 1.5-bisphosphate carboxylase (RBPC, CF 4.1.1.39) in the leaves during active growth of ontogenesis of plants of ordinary bean (Phaseolus vulgaris L.), eggplant (Solanum melongena L.), cucumber (Cucumis sativus L.) and tomato (Solanum lycopersicum L.), of which seeds irradiated at 1, 5, 10, 50, 100, 200, 300 and 400 Gy doses (irradiation rate was p=0.19 Gy/sec). It has been established that CA and RBPC enzymes in the studied plants exhibit similar activity under radiation exposure. The enzyme PEPC has a low catalytic activity due to the photosynthesis mechanism of the plants.
