An RpaA-Dependent Sigma Factor Cascade Sets the Timing of Circadian Transcriptional Rhythms in Synechococcus elongatus

Summary: The circadian clock of the cyanobacterium Synechococcus elongatus PCC 7942 drives oscillations in global mRNA abundances with 24-hr periodicity under constant light conditions. The circadian clock-regulated transcription factor RpaA controls the timing of circadian gene expression, but the...
