%X plants respond to pathogen infection and mechanical or herbivore-induced wounding by localized production of reactive oxygen species (ros), a phenomenon often referred to as the "oxidative burst". although some potential sources of ros in plant cells have been identified, it is still unclear which mechanisms predominate during plant-pathogen interactions. ros have a role in initiating the hypersensitive response, a form of programmed cell death induced by incompatible (avirulent) pathogens, and direct effects on the pathogen, increased oxidative cross-linking of cell wall polymers and induction of pathogen response gene expression. in this paper we focus on the chemistry and the role of these compounds during a plant-pathogen interaction.
