TABLE 2.
E. coli W3110 was the NCBI reference strain (accession no. NC_007779.1). Δ, the mutation site is absent within a larger deleted region. Percent scores indicate breseq calls of less than 100%. Background colors designate strains. Mutation annotations: red, changed base pairs; green, synonymous mutation; blue, missense mutation; purple, IS-mediated deletion; *, nonsense mutation. Mutations present in our laboratory stock strain W3110-D13 compared to the NCBI reference strain (see Table S2 in the supplemental material) are omitted.
