FIG. 5.
Definition of HilA-independent pathways to invasion gene expression. Squares, expression of the indicated transcriptional fusions in the wild-type background; diamonds, expression in the hilA::kan background; circles, expression in the hilA::kan-plus-plasmid background. (A) Overexpression of sirC from pCJ20. (B) Overexpression of sirA from pCJ13d. Error bars represent the standard deviation; the absence of bars indicates that the standard deviation is insignificant. OD600, optical density at 600 nm.
