Transcriptional regulation by iron of genes for siderophore biosynthesis and transport.

∧Pf-5 genes that contain Fur binding motifs upstream [35]. *Values are statistically different as determined using MeV software with P-value <0.01. NS means not significant when analyzed with SAM at FDR <1% in this study. Numbers in bold denote fold changes that surpass the significant differential expression threshold defined in this study, i.e. equal to or exceeding 2-fold change for transcript levels.
