Pathogen infection leads to induction of defense responses which includes modulation of gene expression and changes in metabolism plants. Despite of extensive research little is information known about the role of respiration and photosynthesis during pathogen infection in plants. Limited methods are available to measure oxygen dynamics in response to pathogen infection. Here by using an oxygen microsensor we measured oxygen changes in tomato plants infected with avirulent Pseudomonas syringae pv. tomato DC3000. In this method plant is placed in a closed chamber and change in oxygen levels can be measured by an oxygen sensor.
