Fig. 2.
Diagram of PAO1 iron-controlled genes enhanced or repressed by serum. The arrows with gene number indicate the orientation of the gene on the PAO1 chromosome (Pseudomonas Genome DatabaseV2; http://www.Pseudomonas.com; Winsor et al., 2009). Gene names, if known, are above the arrow, and the fold change is below the arrow. Brackets indicate that genes lie in operons; dashed brackets indicate putative operons. (a) Genes/operons enhanced by serum and directly or indirectly regulated by Fur; black square indicates Fur box (Table 2). (b) Genes/operons enhanced by serum and directly or indirectly regulated by PvdS; black oval indicates iron starvation box (Table 2). (c) Genes/operons repressed by serum. The upstream region of bfrB contains a Fur box-like sequence.
