Research Abstract |
Effects of light illumination on algal cells were analyzed using unicellular red alga, Cyanidioschyzon merolae. During the cell cycle initiation, light is perceived by the light reaction system, and the signal is transferred through MAPK cascade to result in specific CDK activation and organelle DNA replication. In addition, tetrapyrrole signal from the chloroplast was found to inhibit degradation of G1 cyclin, which activates the nuclear DNA replication. In case of light activation of the nuclear transcription, the light reaction is also suggested to be the receptor, but the signal transduction pathway is likely diverged from the early step.
