Fig. 5From: Overproduction of the Flv3B flavodiiron, enhances the photobiological hydrogen production by the nitrogen-fixing cyanobacterium Nostoc PCC 7120hoxE, F genes transcription analysis. Quantitative RT-PCR analysis of hoxE and hoxF gene transcription. RNA were collected form wild type (a, b) or WT/patB-fvl3B (c, d) at different times after the onset of the nitrogen depletion step. Each sample was measured in triplicate and the standard deviation is indicated by error bars. Values were normalized to the rnpB transcriptBack to article page
