Abstract:
:Using two-step-PCR screening which consists of direct and priority-based PCR and inverse PCR, fungal gene-deletion mutants were selected quickly and accurately. It omits genomic DNA extraction and Southern blotting steps and prevents misinterpretations caused by PCR failure. It is anticipated to facilitate large-scale reverse genetic studies in fungi.
