Fast Fission Yeast Genome Editing by CRISPR/Cas9 Using Gap Repair and Fluoride Selection.

We present a protocol to perform CRISPR/Cas9-mediated genome editing in the fission yeast Schizosaccharomyces pombe that does not require cloning and uses the fluoride exporter channel Fex1 as the selection marker. Transformation is typically carried out on the same day of PCR primer arrival and successfully edited strains are selected 5 days after transformation. We expect the adoption of this protocol to further accelerate the throughput of genome editing in S. pombe.
