Abstract

Importance: Cas9-based gene editing tools have revolutionized bacterial genetics, yet, their application to non-model gut bacteria is frequently hampered by various limitations. We utilized a two-plasmid Cas9-based system designed for gene deletion in and demonstrate after optimization its utility for gene editing in three members of the species complex (KoSC) namely , , and . We then adapted a recently developed protocol for functional complementation based on universal "bookmark" targets applicable to all tested species. In summary, species-specific adaptation of state-of-the-art genetic tools allows efficient gene deletion and complementation in type strains as well as natural isolates of KoSC members to study microbial interactions.
