Comparison between GT and ntcA-overexpressing strains of cyanobacteria [nitrogen-replete conditions]

NtcA regulates primary in a unicelluar cyanobacterium Synechocystis sp. PCC6803. We constructed an ntcA-overexpressing strain, named NOX10, by introducing the ntcA genes fusing psbAII promoter by homologous recombination. The transcript profiles of parental wild-type strain GT and NOX10 were compared by microarray CyanoChip (Takrara bio.). Experiments were performed three times with biologically independent RNA. Total RNAs from three independent wild-type (GT) and three independent ntcA-overexpressing strains were differently labeled by Cy3 or Cy5, followed by hybridization on CyanoChip.
