Saxa) [Elektronische Daten] [Andrea A. Wenzel, Horst Mehlhorn] In zinc-deficient bush beans (Phaseolus vulgaris L. cv. Saxa) ozone sensitivity was enhanced compared to plants sufficiently supplied with this nutrient. This was correlated with reduced levels of Cu/ZnSOD activity, but was unrelated to effects of zinc deficiency on transpiration, rates of ethylene formation, ascorbic acid content or levels of MnSOD and ascorbatedependent peroxidase activities. Thus, these results show that detoxification of superoxide anions by Cu/ZnSOD is important in plant resistance to ozone. Additionally, this also indicates the in vivo formation of superoxide anions when plants are exposed to ozone. © Oxford University Press Research Papers nationallicence Ethylene nationallicence ozone nationallicence ascorbate peroxidase nationallicence superoxide dismutase nationallicence zinc deficiency nationallicence Wenzel Andrea A.
