Just as low-oxygen levels stress plants that are exposed to flooding, so does post-flooding reoxygenation and the associated burst of reactive oxygen species. Work @nature, shows that in both cases, the same molecular players mediate plants’ stress response.

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.
