CRISPR-Cas9 Genome Editing in Auxotrophic and Non-auxotrophic Fission Yeast Strains.

The CRISPR/Cas system is a very powerful genome-editing tool that has been developed over the past decade to optimize genome editing for many organisms. Here, we describe a rapid genome-editing method for fission yeast using the CRISPR-Cas9 system. It allows rapid generation of desired auxotrophic and non-auxotrophic strains without perturbing the local genome content by avoiding the insertion of selection markers at target loci.
