OsDUF2488 acts synergistically with OsPrx1.1, regulates ROS metabolism and promotes dehydration tolerance in rice.

ABSTRACT: Stress-mediated regulation of energy metabolism and its relation to plant adaptation remain largely unknown. Mitochondrial redox potential is greatly influenced by stress-induced reactive oxygen species (ROS); therefore, we mapped the dehydration-induced alterations in the mitochondrial proteome of a resilient rice cultivar, Rasi, generating a proteome map representing the largest inventory of dehydration-responsive mitochondrial proteins from any plant species. Quantitative proteomic analysis led to the identification of an array of dehydration-responsive proteins (DRPs), associated with various cellular functions, conceivably impinging on the molecular mechanism of adaptation. One DRP identified in the mitochondrial proteome was yeast cadmium factor 54 (YCF54-like), also known as DUF (do
