Ethylene and hydrogen peroxide are involved in hypoxia signaling that modulates AtERF73/HRE1 expression

Figures & data

Figure 1. Model for the involvement of AtERF73/HRE1 and ADH1 transcripts in hypoxia and ethylene-H₂O₂ mediated pathways. Hypoxia triggers ethylene and H₂O₂ production, which increases the accumulation of AtERF73/HRE1 transcripts through (I) an ethylene-dependent pathway, (II) an ethylene-independent/H₂O₂-dependent pathway, and (III) an ethylene/H₂O₂-independent pathway. AtERF73/HRE1 positively regulates ADH1 genes and negatively regulates a set of peroxidase and cytochrome P450 genes in hypoxia signaling.
