Abstract

Chemically inducible chromosomal evolution (CIChE) was developed for stable multicopy chromosomal integration of heterologous genes. In this technique, flanking an antibiotic selection marker and a gene of interest with identical regions of homology permits gene duplication via recA mediated homologous recombination. A strong selective pressure for gene duplication can be applied by increasing antibiotic concentration, and in a week’s time one can create a set of strains with a wide range of cassette copy numbers (upward of 20×), which can be made stable by deletion of recA. Herein, we describe a generalized workflow for this methodology.
