Circadian transcriptional profile of Synechococcus without KaiC phosphorylation cycling

ABSTRACT: In the unicellular cyanobacterium, Synechococcus elongatus PCC 7942, essentially all promoter activities are under the control of the circadian clock in continuous light (LL) conditions. Here, we employed high-density oligonucleotide arrays to investigate comprehensive profiles of genome-wide Synechococcus gene expression in the kaiCEE mutant strains in which the KaiC phosphorylation cycling is abolished under LL.. In the kaiCEE mutant strain more than 23% of transcripts significantly oscillated with a period of about 48 h. 409 cyclic genes were shared with the wild type strains. kaiCEE mutant strain was analyzed under continuous light (LL) using Affymetrix high-density oligonucleotide microarrays (GeneChip CustomExpress Arrays) representing predicted 2,515 protein-coding genes on the geno
