| Outline of Final Research Achievements |
For phototrophic microorganisms, it is important to inhabit under suitable light environment for phototaxis. Previously, we found that Chlamydomonas reinhardtii, a model organism to study photo-behavioral responses, shows positive phototaxis when cell is oxidized, and negative phototaxis when it is reduced. We came up with the idea to use this phenomenon as a new criterion for screening of novel-type photosynthesis mutants. In this research, we isolated three types of phototaxis-sign mutants, and one of them shows significantly high photosynthetic activity.
