Figure 6. Relative expression of selected swimming motility related genes.
Total RNA was extracted from the wild-type and △wzxC1 mutant grown in LB and NB medium. flgA, motA, motB, cheA and cheB expression was analyzed by quantitative RT-PCR. Average fold changes in gene expression in the mutant at each culture condition compared with those of the wild-type are shown. recA was used as an internal control. Errol bars indicate standard deviations. Stars indicate that the fold-changes in gene expression were significantly different (p-value, 0.05).
