FIG 4.
Expression factors of the indicated genes in A. baumannii strains. Rifr5C and Rifr8C represent the complemented rifampin-resistant strains Rifr5 and Rifr8, respectively, carrying the vector pBAV1K-T5-gfp with the wild-type rpoB gene. The expression factor is the ratio of the mRNA concentration of each gene from the indicated strain with respect to the wild-type A. baumannii parental strain (ATCC 17978). The error bars represent the standard deviations of the mean of at least two independent experiments, each carried out in duplicate.
