In this study, an efficient CRISPR\/Cas9 genome\u2010editing system based on an autonomously replicating plasmid with an AMA1 sequence was constructed. Further, a precisely targeted gene deletion via homology\u2010directed repair was effectively introduced in\n                    <jats:italic>C. militaris<\/jats:italic>\n                    .

Plasmid loss was observed under non\u2010selective culture conditions, which could permit recycling of the selectable marker and avoid the adverse effects of the CRISPR\/Cas9 system on the fungus, which is beneficial for the generation of new cultivars.
