Abstract

We previously showed that nuclear DNA replication (NDR) is regulated by a checkpoint monitoring the occurrence of organelle DNA replication (ODR) in a unicellular red alga Cyanidioschyzon merolae. These analyses depended on the use of chemical CDK inhibitors such as CDK2 inhibitor II and roscovitine, but subsequent analyses yielded conflicting results depending on the experimental conditions. In the present study, we identified significantly short half-lives of the used chemicals in the sulfur acidic cultivation medium, which reconciles the discrepancy among these results.
