Figure 5.
Microarray deletion map of deletions found in strains Δ20-1 and Δ20-4. Each dot represents the log ratio of normalized signal intensities for a particular ORF from the deletion strain to its control strain counterpart. Deletion regions were determined by consecutive signal ratios of E. coli ORFs below 1 andP-values <0.05. These hybridization results were plotted against base pair location for comparison with a NotI restriction map (Heath et al. 1992).
