A new circadian class 2 gene, opcA, whose product is important for reductant production at night in Synechococcus elongatus PCC 7942.

Abstract excerpt

Gene expression in the cyanobacterium Synechococcus elongatus PCC 7942 is under the control of a circadian oscillator, such that peaks and troughs of expression recur with a periodicity of about 24 h in the absence of environmental cues. This can be monitored easily as light production from luciferase gene fusions to S. elongatus promoters. All promoters seem to exhibit circadian oscillation of expression, but...
