In modeling experiment the specificity of glutathione-dependent enzymes activation and reduced glutathione pool enhancing in apical meristem and growth zone of roots of maize (Zea mays L.) seedlings under cadmium and higher temperature action was found. The functioning of independent modes for regulation of metabolic glutathione cycle in cells from different zones of seedlings roots under abiotic stressors action was discussed.
