| Research Abstract |
Photosynthetic organisms are known to perceive environmental changes as changes in redox state of photosynthetic electron transport chain to start transcriptional regulation. However, information on transcriptional regulators working on the process has been very limited. In this study, we established the new screening system to detect interaction between a transcriptional regulator and the redox-dependent regulatory protein, thioredoxin. We successfully identified five transcriptional regulators as new targets of thioredoxin using this screening system. By characterizing these regulators, the mechanism of photosynthetic electron transport-dependent transcriptional regulation will be elucidated.
