a pOF105 and pRF01 plasmid maps. b Knock-in strategy of gyrAam and rpsLam into the arsB gene locus by λ-red recombination and (c) genotyping of the arsB gene locus in KS40 and RF01. The small arrows above/below the genes in (b) indicate the primers used for genotyping by PCR, which is shown in (c). The chain lengths of amplicons derived from KS40 and RF01 genomic DNAs were 1115 and 8391 bp, respectively
