Tiivistelmä

Reactive oxygen species (ROS) carry out vital functions in determining
appropriate stress reactions in plants, but the molecular mechanisms
underlying the sensing, signaling and response to ROS as signaling
molecules are not yet fully understood. Recent studies have underscored
the role of Protein Phosphatase 2A (PP2A) in ROS-dependent responses
involved in light acclimation and pathogenesis responses in Arabidopsis
thaliana. Genetic, proteomic and metabolomic studies have demonstrated
that trimeric PP2A phosphatases control metabolic changes and cell death
elicited by intracellular and extracellular ROS signals. Associated
with this, PP2A subunits contribute to transcriptional and
post-translational regulation of pro-oxidant and antioxidant enzymes.
This review highlights the emerging role of PP2A phosphatases in the
regulatory ROS signaling networks in plants.
