Abstract excerpt
While bacteriophage applications benefit from effective phage engineering, selecting the desired genotype after subtle modifications remains challenging. Here, we describe a two-phase endogenous CRISPR-Cas-based phage engineering approach that enables selection of small defined edits in Pectobacterium carotovorum phage ZF40. We designed plasmids containing sequences homologous to ZF40 and a mini-CRISPR array. The...
