Proteome-wide mapping of early events connected to oxidative stress in Arabidopsis

Changes in environmental conditions are associated with the fast accumulation of reactive oxygen species, which may rapidly generate an oxidative environment. For efficient survival, plants respond by rapid changes in protein turnover, gene expression and posttranslational protein modifications. For this reason, the regulation of ROS levels requires rapid protective mechanisms including of antioxidant defense. Here, we aimed to delineate the early events associated with the response of Arabidopsis to methyl viologen on proteome level.
