The correct integration of the detoxification processes in a risk assessment model for ozone damage on plants remains challenging. In particular, the intracellular compartmentation of antioxidant metabolites could play a role, since each compartment presents its own sensitivity to ROS and metabolite set. For each compartment, we tried to provide both qualitative and quantitative information on the metabolites present as well as the putative transporters implied. When they are known, the modifications caused by O3 or oxidative stress are presented. Clearly, under O3 exposure, integrative data which would allow to improve predictive models for O3 risk assessment are missing.
