Dictyostelium discoideum is an exceptionally powerful eukaryotic model to study many aspects of growth, development, and fundamental cellular processes. Its small-sized, haploid genome allows highly efficient targeted homologous recombination for gene disruption and knock-in epitope tagging. We previously described a robust system for the generation of multiple gene mutations in Dictyostelium by recycling the Blasticidin S selectable marker after transient expression of the Cre recombinase. We have now further optimized the system for higher efficiency and, additionally, coupled it to both, knock-out and knock-in gene targeting, allowing the characterization of multiple and cooperative gene functions in a single cell line.
