Cover Story: CRISPR is dramatically accelerating strain construction to enhance product discovery, cell factory development, and our understanding of fungal biology. Importantly, the use of CRISPR/Cas9 has been troubled by intellectual property issues in industrial and pharmaceutical sectors. With the aim of introducing new avenues for commercial fungal strain engineering, we show here that the IP-friendly CRISPR nuclease Mad7 can be used as an efficient alternative to Cas9 for genetic engineering of filamentous fungi. Specifically, we show that Mad7-induced DNA breaks can be used to introduce undefined and template-directed defined mutations into a specific site. Moreover, we show that Mad7 can be used for deleting a specific gene or to insert a gene of interest into a defined expression site.
