Характеристика морфогенной линии каллуса, устойчивой к действию ингибитора каталазы

Abstract

It was shown that callus line 1–8 AT is resistant to the action of a specific inhibitor of catalase — 3-aminotriazole (AT), but catalase in this line is sensitive to this inhibitor. At the same time suppressing the activity of catalase not cause increase in the content of H2O2 in the cells, which may indicate a compensatory operation of another mechanism contributing to the destruction of H2O2 or reducing its formation in the 1–8 AT line. Since the resistance to AT remained in the medium without inhibitor for 45 passages, it may indicate the mutant nature of the selected line.
