Editor's Summary

Surviving Submergence
Although plants need water to survive, too much of a good thing can be devastating: Submergence in water limits the diffusion of oxygen and thereby aerobic metabolism and energy production. Therefore, flooding represents a potential disaster that can wipe out crops. Lee et al. investigated the mechanisms that allow rice seedlings to survive flooding and discovered that CIPK15 [calcineurin B–like (CBL)–interacting protein kinase]—a protein kinase previously implicated in mediating various stress responses—integrates the response to hypoxia with that to sugar depletion to regulate anaerobic carbohydrate metabolism under flooded conditions. Thus, rice seedlings survive—and continue to grow—even when submerged in water.
