Analyzing the Function of Catalase and the Ascorbate-Glutathione Pathway in H

Plant stress involves redox signaling linked to reactive oxygen species such as hydrogen peroxide (H We discuss several implications of the modeled results, in particular the following. (i) CAT and ascorbate peroxidase can share the load in H Important future questions include the roles of other antioxidative systems in interacting with CAT and the ascorbate-glutathione pathway as well as the nature and significance of processes that achieve redox exchange between different subcellular compartments. Progress in these areas is likely to be favored by integrating kinetic modeling analyses into experimentally based programs, allowing each approach to inform the other.
