Figure 7From: Electrochemical selection and characterization of a high current-generating Shewanella oneidensis mutant with altered cell-surface morphology and biofilm-related gene expression qRT-PCR analyses of the metR , metE , and luxS genes in WT, EC-2, and ∆SO_1860 cells. Results are expressed as log2-fold changes (FC) relative to expression levels in WT cells. The error bars represent the standard deviation calculated from at least four measurements. Asterisks indicate a statistically significant difference (P < 0.05) between expression levels in the three strains.Back to article page
