Five mutants (called tnm) of Escherichia coli with impaired ability for transposition of Tn9 were isolated after treatment with ethyl methanesulfonate (EMS) or N-methyl-N'-nitro-N-nitrosoguanidine (NG). The map locations of the tnm mutations were determined by a combination of Hfr matings, F' episom
From a collection of 8,000 transposon-insertion mutants of Escherichia coli K12 we identified two mutations, trg-1::Tn5 and trg-2::Tn10, that simultaneously eliminate chemotactic response to ribose and galactose, two attractants recognized by independent receptors. We show that these transposon-inse
