Popis: In this communication, we report the adaptation of the CRISPR-Cas9 technology in Ustilago trichophora prototrophic wild-type isolate obtained from its natural host Echinochloa crus-galli. The established CRISPR vector and method enable a rapid and marker-free introduction of Cas9-induced non-homologous end-joining (NHEJ) dependent mutation at the targeted gene. Moreover, the method allows a specific modification of the chromosomal DNA sequence by Cas9-induced homologous recombination using short DNA repair templates. The results demonstrate the applicability of the CRISPR-Cas9 technology in U. trichophora for both gene knock-out by the NHEJ pathway and specific gene modification by templated genome editing, paving the way for rapid metabolic engineering of this Ustilago species for industrial applications.
