Hypoxia induces H2O2 production and activates antioxidant defence system in grapevine buds through mediation of H2O2 and ethylene

Paradoxically, in eukaryotic cells, hydrogen peroxide (H(2)O(2)) accumulates in response to oxygen deprivation (hypoxia). The source of H(2)O(2) under hypoxia varies according to the species, organs, and tissue. In non-photosynthetic tissues, H(2)O(2) is mainly produced by activation of NAD(P)H-oxid...
