Abstract

How plants sense oxygen shortage Tolerance of plants to flooding is an important factor for food security, particularly in the developing world. When plants are submerged in water they experience hypoxia, which triggers changes in gene transcription that promote anaerobic metabolism and sustain ATP production. Two complementary studies identify the mechanism that senses reduced oxygen levels in Arabidopsis. They report that the N-end rule pathway of targeted proteolysis regulates the stability of key hypoxia-response transcription factors. Enhanced stability of these proteins under low oxygen conditions improves plant survival, suggesting a target for possible genetic improvement of flooding-tolerance in crops.
