H₂O₂ repurposes plant O₂ sensing to regulate post-hypoxia responses

Nature, Published online: 22 April 2026; doi:10.1038/s41586-026-10366-1

Experiments in Arabidopsis demonstrate that group VII ethylene response factors show differential responses to different stimuli, enabling plants in flood-prone environments to adapt to both submergence-induced hypoxia and reoxygenation upon desubmergence.
