ABSTRACT
Gene editing technology can be used to modify the genome of Escherichia coli for the investigation of gene functions, or to change the metabolic pathways for the efficient production of high-value products in engineered strains with genetic stability. A variety of gene editing technologies have been applied in prokaryotes, such as λ-Red homologous recombination and CRISPR/Cas9. As a traditional gene editing technique, λ-Red recombination is widely used. However, it has a few shortcomings, such as the limited integration efficiency by the integrated fragment size, the cumbersome gene editing process, and the FRT scar in the genome after recombination. CRISPR/Cas9 is widely used for genome editing at specific sites, which requires specific DNA segments according to the editing site. As the understanding of the two technologies deepens, a variety of composite gene editing techniques have been developed, such as the application of λ-Red homologous recombination in combination with homing endonucleaseⅠ-SceⅠ or CRISPR/Cas9. In this review, we summarized the basic principles of common gene editing techniques and composite gene editing techniques, as well as their applications in Escherichia coli, which can provide a basis for the selection of gene editing methods in prokaryotes.
