Outline of Final Research Achievements

Acaryochloris marina is the cyanobacterium that can utilize far-red light for photosynthesis, whereas most other oxygenic photosynthetic organisms cannot use the light. However, the lack of molecular genetic techniques for A. marina prevented us from studying this organism deeply. In this project, we aimed to develop the molecular genetic techniques for A. marina in order to elucidate the adaptation mechanism of A. marina to far-red light utilization. In the result of this study, we succeeded in introducing a foreign gene into A. marina using an expression vector. We also succeeded in producing transposon-tagged mutants of A. marina by transposon tagging.
