Expression of hexokinase (HK, A), 6-phosphofructokinase (PFK, B), pyruvate kinase (PK, C), isocitrate dehydrogenase (IDH, D), malate dehydrogenase (MDH, E) and succinate dehydrogenase (SDH, F) isozymes in cucumber roots exposed to one of three treatments for 3 d. These three treatments were normoxic conditions (Control), hypoxia treatment (Hypoxia) and hypoxia + 4 mM CaCl2 treatment (Hypoxia + Ca2+). Lines indicate the isozymes detected by staining.
