Coordinated responses to oxygen and sugar deficiency allow rice seedlings to tolerate flooding.

Abstract excerpt

Flooding is a widespread natural disaster that leads to oxygen (O(2)) and energy deficiency in terrestrial plants, thereby reducing their productivity. Rice is unusually tolerant to flooding, but the underlying mechanism for this tolerance has remained elusive. Here, we show that protein kinase CIPK15 [calcineurin B-like (CBL)-interacting protein kinase] plays a key role in O(2)-deficiency tolerance in rice....
