要旨

Due to their biotechnological relevance as well as their importance as disease agents, filamentous fungi and oomycetes have been prime candidates for genetic selection and in vitro manipulation for decades. With the advent of new genome editing technologies such manipulations have reached a new level of speed and sophistication. The CRISPR-Cas9 genome editing technology in particular has revolutionized the ways how desired mutations can be introduced. To date, the CRISPR-Cas9 genome editing system has been established in more than 40 different species of filamentous fungi and oomycetes. In this review we describe the various approaches taken to assure expression of the components necessary for editing and describe the varying strategies used to achieve gene disruptions, gene replacements and precise editing. We discuss potential problems faced when establishing the system, propose ways to circumvent them and suggest future approaches not yet realized in filamentous fungi or oomycetes.
