| Outline of Final Research Achievements |
Regulation of DNA replication is essential for maintaining precise chromosomal copy number in all organisms. In yeast and animal cells, the mechanism of DNA replication initiation has been revealed, however the observation of that is very limited in algae and green plants. Cyanidioschyzon merolae is unicellular red algae, living under high temperature and strong acidity such as hot spring. C. merolae have simple cell structure and genome, thus this organism is suitable to study the basic principle of plant DNA replication initiation mechanism. In this study, we investigated DNA replication start sites in C. merolae by ChIP-seq and Repli-seq analysis and found several candidates. In addition, we constructed vector contains marker gene and centromere for the platform of artificial chromosome. Our study will contribute for not only understanding plant DNA replication but also developing algae genome biology.
