Sequencing of transposon flanking genes
Transposon–flanking sequences were amplified by the Y-linker
method [46,90]. Oligonucleotide sequences (Y-linker, Tn5MOD)
are listed in Table 4. The Y-linker was prepared by the annealing of
two oligonucleotides, Y1 and Y2. Genomic DNA of the mutants in
aliquots of 1 mg was cut with 5 U NlaIII or SphI (New England
