Construction and characterization of ΔlgtB and Δlex-1 mutants and complemented strains. (A) Parts 1–3 show the maps of the lgtB gene of wild-type SC096, the lgtB::KanR insertion mutant and its complemented strain. Parts 4–6 show the maps of the lex-1 gene of wild-type SC096, the lex-1::KanR insertion mutant and its complemented strain. (B) Part 1, Primers P1 and P4 were used to amplify upstream to downstream of lgtB from the ΔlgtB mutant strain (lane 1), the wild type SC096 (lane 2); Primers P5 and P8 were used to amplify upstream to downstream of lex-1 from the Δlex-1 mutant strain (lane 3), the wild type SC096 (lane 4). Part 2, Primers P11 and P15 were used to amplify lgtB and GmR from the ΔlgtB-c strain (lane 1), the wild type SC096 (lane 2); Primers P13 and P15 were used to amplify lex-1 and GmR from the Δlex-1-c strain (lane 3), the wild type SC096 (lane 4).
