The Mitochondrial Glutathione Peroxidase 3 (OsGPX3) regulates ABA responses in rice plants


ABSTRACT: We demonstrate that the mitochondrial isoform of rice GPX (OsGPX3) is involved in the responses to the phytohormone abscisic acid (ABA) and in epigenetic modifications. Silenced plants for OsGPX3 present important changes in the accumulation of proteins related to these processes.

Different environmental conditions can lead plants to a condition termed oxidative stress, which is characterized by a disruption in the equilibrium between the production of reactive oxygen species (ROS) and antioxidant defenses. Glutathione peroxidase (GPX), an enzyme that acts as a peroxide scavenger in different organisms, has been identified as an important component in the signaling pathway during the developmental process and in stress responses in plants and yeast. Here, we demonstrate t  ...[more]
