FIG. 2.

Schematic representations of chromosomal loci of ArgR-regulated genes. Only new genes of the ArgR regulon identified and subjected to further analysis in this study are shown as black arrows, and genes in their flanking regions are shown as gray arrows. The DNA fragments used in the construction of translational fusions of lacZ (white arrows) or in gel retardation assays are depicted as filled bars. The nomenclature and genetic organization of these genes are based on the current version of the Pseudomonas Genome Project (www.pseudomonas.com).
