Technical Abstract: A new area of disease physiology has emerged reporting the involvement of active oxygen (AO) species in plant pathogenesis. As in any new field there has been a flurry of initial reports linking AO species with key events in plant/pathogen interactions including signal transduction, antimicrobial effects, membrane lipoxidation, cell wall modification, induced resistance, and hypersensitive cell death. Because of the extraordinary potential impact of AO on several aspects of plant/pathogen interactions it is important that we be aware of its existence as well as to better understand the cellular mechamisms that govern its metabolism. The purpose of this chapter is to provide a critical review and update on some of the current hypotheses regarding the production and role of AO during plant/pathogen interactions and to comment on the future direction and needs to AO research. In order to accomplish this, a brief overview of AO metabolism and detection will be covered along with an updated description of its production during plant/pathogen interactions. We have broken AO involvement in pathogenesis into 3 phases: recognition, resistance, and senescente.
