| Outline of Final Research Achievements |
We have examined the regulatory loop in which the nucleus and the chloroplast of plant cells control each other, especially stressed in the genome transcription and replication. The experimental system was simplified by using the primitive red alga Cyanidioschyzon merolae, and it was shown that signals derived from the chloroplast as well as the mitochondrion were essential for both of the organelle and nuclear DNA replications. We have also made clear specificities of nuclear-encoded chloroplast sigma factors, and studied the signaling pathway from light-activated chloroplast to the nuclear genome transcription.
