Oligonucleotide Recombination Enabled Site-Specific Mutagenesis in Bacteria

Recombineering refers to a strategy for engineering DNA sequences using a specialized mode of homologous recombination. This technology can be used for rapidly constructing precise changes in bacterial genome sequences in vivo. Oligonucleotide recombination is one type of recombineering that uses ssDNA oligonucleotides to direct chromosomal mutations. Oligo recombination occurs without addition of any exogenous functions, making this approach potentially useful in many different bacteria. Here we describe the basic technique for constructing a site-specific genomic mutation in Pseudomonas syringae.
