| Research Abstract |
The redox state of higher plant chloroplast varies greatly under light and dark conditions. Many proteins, including enzymes related to photosynthesis, are activated depending on its redox state. However, its mechanism remains to be fully elucidated. In this project, we focused on thioredoxins, which act as regulator of proteins in chloroplast stroma. Arabidopsis mutants defective in accumulation of thioredoxins were obtained and analyzed, which revealed that thioredoxins are important for photosynthesis and photoprotection.
