Outline of Final Research Achievements

In order to get information on the mechanism of plant tolerance to ozone, we carried out genetic and physiological analyses on the isolated Arabidopsis ozone-sensitive mutant. We obtained results that the gene responsible for the mutant's ozone sensitivity encodes a photorespiratory enzyme, glycolate oxidase, and the ozone sensitivity was due to the reduced enzyme activity. This mutant also exhibited high sensitivity against sulfur dioxide and a long-term high-intensity light. Two mutant lines that have defects in other photorespiratory enzymes also exhibited high ozone sensitivities. These results suggest that intact photorespiratory flow is neccessary for the plant tolerance to ozone as well as other stress factors.
