Ethylene-mediated nitric oxide depletion pre-adapts plants to hypoxia stress

Ethylene-mediated nitric oxide depletion pre-adapts plants to hypoxia stress

Plant hypoxia responses are controlled by oxygen and nitric oxide (NO)-dependent proteolysis of ERFVII transcription factors. Here Hartman et al. show that passive ethylene entrapment during root submergence enhances NO-scavenger PHYTOGLOBIN1, ERFVII stability and promotes subsequent hypoxia toleran...

Description
Résumé:Plant hypoxia responses are controlled by oxygen and nitric oxide (NO)-dependent proteolysis of ERFVII transcription factors. Here Hartman et al. show that passive ethylene entrapment during root submergence enhances NO-scavenger PHYTOGLOBIN1, ERFVII stability and promotes subsequent hypoxia tolerance.
