Figure 2. Effect of XrpA on activation of comX and comS promoters.

Figure 2

Transcriptional activation assays using a fused-gfp reporter for (A) PcomX and (B) PcomS in wild-type (UA159 – green circles), comX::T162C (ΔxrpA – blue squares) or xrpA overexpression (184XrpA – orange diamonds) genetic backgrounds. Black lines represent growth (OD600, right axis) of each of the respective reporter strains during the assay. Each data point shown is the average of three independent biological replicates with four measured technical replicates.
