  1. Relative expression (log2(fold-change) [log2FC]) of genes encoding for quinone biosynthesis and oxido-reductases of the respiratory chains of Kp13 for bacterial growth in polymyxin (PB) versus control condition (non-induced). Criteria for significance: FDR≤0.01. log2FC values in bold, positive denotes up-regulation in PB and log2FC in bold, negative denotes down-regulation in polymyxin. log2FC in italic font are not significant based on FDR. bThese comparisons gave significant differentially expressed genes at a FDR of ≤0.05
