Class-1 hemoglobin and antioxidant metabolism in alfalfa roots

In the course of nitric oxide (NO) scavenging, hemoglobin (Hb) turnover is linked to antioxidant metabolism and affects the cellular redox level. The influence of Hb presence on the ascorbate-glutathione cycle enzymes and the levels of H2O2 and ascorbate was investigated in alfalfa root cultures tra...
