Differential expression of the ICEclc gene region from micro-array data in selected mutant ICEclc versus wild type in P. putida UWC1.
(A) Differential expression of the ICEclc region between stationary and exponential phase cells of wild type P. putida UWC1 (ICEclc). (B) Differential expression of the ICEclc region between the mfsR deletion mutant and wild-type, in exponentially growing cells. (C) Comparison of the tciR deletion mutant and wild-type, in stationary phase cells. (D) Comparison of the mfsR transposon insertion mutant versus wild-type, in stationary phase cells. Dots indicate the 2log-fold change of hybridization signal per microarray probe in the comparison, plotted at their distance along the ICEclc sequence (X-axis; in kb). Regions of interest on ICEclc are redrawn as grey boxes at the bottom of each section (+ or - indicate the DNA strand on which the region is encoded). Separate displays indicate expression differences on the plus- (open symbols) or the minus-strand (closed symbols). Grey bars in the background indicate the two-fold cut-off level.
