| Outline of Final Research Achievements |
When the cyanobacterium Synechocystis sp. PCC 6803 had acclimated to strong light, the intracellular level of translation factor EF-Tu rose. The increased amounts of EF-Tu protected protein synthesis from oxidative injury and enhanced the repair of photosystem II under strong light, with the resultant mitigation of photoinhibition of photosystem II. Similarly, the level of EF-Tu in the chloroplast of Arabidopsis thaliana rose in the plants that had acclimated to strong light, suggesting that a similar protective mechanism might be developed in Arabidopsis.
