Unraveling hydrogen peroxide signaling in Arabidopsis thaliana

Sandy Vanderauwera UGent (2007)
abstract
Reactive oxygen species (ROS) are toxic molecules that, at high concentrations, result in non-controlled oxidation of a variety of cellular structures, which ultimately lead to disruption of metabolism and destruction of cellular structures. Because plant cells are continuously generating ROS as products of normal aerobic metabolism, it is not surprising that plants also possess a range of antioxidant mechanisms to prevent ROS from reaching destructive levels. However, ROS are far more important to plant biology than simply as toxic by-products and agents of cellular damage. At low concentrations, they are key signaling molecules that regulate growth and development and coordinate responses to biotic and abiotic stress. At the beginning of my PhD, evidence on the importance of ROS as cellular regulators was starting to emerge and the primary objective of the work presented here was to extend this knowledge by means of large-scale identification of H2O2-responsive transcripts in catalase-deficient Arabidopsis thaliana. Similar to catalase-deficient tobacco plants, these plants are an ideal tool to modulate H2O2 levels in planta. Not only were these large-scale transcriptome analyses designed to provide a comprehensive inventory, but also to reveal specific biological processes in which H2O2 is involved. Moreover, they aimed to elucidate interesting candidates for further molecular-genetic characterization.
