Project description:In order to explore the effect of introducing the ectoine synthesis module in Synechococcus elongatus PCC 7942 on the global regulation of the strain under high-salt environment. The ectoine synthesis module was introduced at the Synpcc7942_0808 locus to obtain the Syn7942/Δsps-ect strain that lacked sucrose synthesis and could synthesize ectoine. Comparative transcriptomic analysis was performed on WT and Syn7942/Δsps-ect under 0 mM and 300 mM NaCl conditions.

Project description: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 kaiA-overexpressor (Ptrc::[GTG]kaiA) strains under LL. KaiC has been proposed to globally activate gene expression, our analysis revealed that dawn expressing genes were downregulated by kaiA-overexpression, such that the clock was arrested at subjective dawn. IPTG-inducible kaiA-overexpressor (oxA) S. elongatus PCC 7942 strains were analyzed under continuous light (LL) using Affymetrix high-density oligonucleotide microarrays (GeneChip CustomExpress Arrays) representing predicted 2,515 protein-coding genes on the genome of Synechococcus elongatus PCC 6301, which can be used also to the almost homologous strain, S. elongatus PCC 7942: a single experiment in oxA under LL in the presence or absence of an inducer, IPTG, from hour 24 to 48 in LL timecourse data (24~48 hours under continuous light) from Synechococcus elongatus PCC 7942 (inducible kaiA-overexpressor) strains

Project description: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 genome of Synechococcus elongatus PCC 6301, which can be used also to the almost homologous strain, S. elongatus PCC 7942: a single experiment in kaiCEE mutant under LL from hour 8 to 96 in LL timecourse data (8~96 hours under continuous light) from Synechococcus elongatus PCC 7942 (kaiCEE mutant) strains

Project description:In the unicellular cyanobacterium, Synechococcus elongatus PCC 7942, most of genes are downregulated in the dark, while 10% of genes are upregulated. Here, we employed high-density oligonucleotide arrays to explore comprehensive profiles of genome-wide Synechococcus gene expression in wild type and kaiABC-null strains under continuous dark (DD) conditions. We found that expression profile of a subset of genes on the genome in DD was dramatically affected by kaiABC-nullification, and the magnitude of dark-induction was dependent on time when cells were transferred from light to DD Keywords: timecourse data (0-12 h) under continuous darkness after dark:light cycles from Synechococcus elongatus PCC 7942 wild type and kaiABC-null strains Wild type (WT) and kaiABC-null (DkaiABC) S. elongatus PCC 7942 strains were analyzed under continuous dark (DD) conditions after two 12h:12h light:dark (LD) cycles using Affymetrix high-density oligonucleotide microarrays (GeneChip CustomExpress Arrays) representing predicted 2,515 protein-coding genes on the genome of Synechococcus elongatus PCC 6301, which can be used also to the almost homologous strain, S. elongatus PCC 7942: Two independent experiments in WT and Dkai strains under DD (hours 0, 0.5, 1, 2, 4, 8 and 12).

Project description:In the unicellular cyanobacteriuIn the cyanobacterium, Synechococcus elongatus PCC 7942, most genes show rhythmic expression controlled by the Kai-based clock under continuous light conditions (LL). Overexpression of clpX led to a decrease in kaiBC promoter activity, disruption of circadian rhythm, and eventually cell death. We found that overexpression of clpX upregulated mRNA levels of ribosomal protein subunits, after which expression of other genes containing the clock genes was decreased. Wild type (WT) and inducible clpX-overexpressor (ox-clpX) S. elongatus PCC 7942 strains were analyzed under continuous light (LL) using Affymetrix high-density oligonucleotide microarrays (GeneChip CustomExpress Arrays) representing predicted 2,515 protein-coding genes on the genome of Synechococcus elongatus PCC 6301, which can be used also to the almost homologous strain, S. elongatus PCC 7942: WT at hours 16 in LL (IPTG-free): WT under LL 20 in LL (addition of 100 µM IPTG for 4 hours): ox-clpX cells at hours 16 in LL (IPTG-free): ox-clpX cells at hours 20 in LL (addition of 100 µM IPTG for 4 hours)
