General Information

General Information Comment Organism
physiological function ascorbate peroxidase (APS) is an important antoxidant enzyme responsible for the conversion of H2O2 to H2O and O2. Role of APX in the tolerance of the boreal cushion moss Dicranum scoparium to abiotic stress Dicranum scoparium
