1. Location is given based on the MG1655 genome (GenBank accession # U00096.2) 2. Detected differences were reported by Nimblegen as Single Nucleotide Polymorphisms (SNPs) or in non-called Regions Of Interest (ROIs). Most differences detected in ROIs were reported by multiple nearby probes, but were reported in only one probe in cases as noted. 3. This column indicates whether the sequence difference is present in the published genome sequence of W3110.
