Transcript analyses of genes involved in hydrogen metabolism (A) and photosynthesis pathway (B). RT-PCR using total RNA isolated from wild type and ∆hupS cells grown in BG110 medium without N-source for 12 h. The PCR amplification using cDNAs of respective genes were performed using specific primers. 23S rRNA was used as control when determining the relative level of the respective transcript and the intensities of the PCR generated DNA fragments were determined by using GeneTools program.
