| Research Abstract |
We demonstrated in Synechococcus the presence of circadian transcriptional regulation even without de novo transcription/translation of clock genes in the dark conditions. Moreover, we identified a response regulator gene, rpaB, as an important regulator of clock gene expression. In the multicellular cyanobacterium, Anabaena sp. PCC 7120, we described basic circadian transcriptomic profiles and revealed the presence of circadian transcription rhythms in heterocysts.
