Figure 1. Gene expression analysis in logarithmically growing cultures of parA null, parB null strains versus WT P. aeruginosa.

Figure 1

(A) Quality analysis of three biological replicates of studied strains parA null, parB null and WT of PAO1161 P. aeruginosa by principle component analysis (PCA) of data obtained from expression microarray analysis. The first principle component (PC#1) accounted for 68% and the second principle component PC#2 for 19.7% of the total variation in the dataset. The plot indicates that the transcriptome data are of high quality as the samples cluster together according to the strain: green - WT, red - parA null, blue - parB null. (B) and (C) Cluster analysis of the normalized gene expression for genes that were differentially regulated in parA null and parB null strains as compared to the WT, respectively.
