† C600 lines obtained from different sources give different results. The original strain and that obtained from the E. coli Genetic Stock Center (Yale University) are McrA+; derivatives traceable to the Brenner laboratory are McrA (18).

†† No isolates of these strains tested showed pleiotropic phenotypes attributed to lon (i.e. were not mucoid, formed turbid λ plaques, grew well on rich media

The designation R(...) means Rearrangement by analogy with IN(...) for INversion (19). Thus, "R(xxx::Tn10--TetS)" signifies the former presence of a Tn10 insertion. For insertions of wild-type Tn10, the rearrangement was presumably Tn10 promoted, since 99% of TetS derivatives of Tn10-containing strains have acquired transposon-promoted rearrangements (20, 21, 22) that spare one or both IS10 elements.
