Efficient genome editing using endogenous U6 snRNA promoter-driven CRISPR/Cas9 sgRNA in

We previously reported on a CRISPR-Cas9 genome editing system for the necrotrophic fungal plant pathogen Sclerotinia sclerotiorum. This system (the TrpC-sgRNA system), based on an RNA polymerase II (RNA Pol II) promoter (TrpC) to drive sgRNA transcription in vivo, was successful in creating gene ins...

520			\|a We previously reported on a CRISPR-Cas9 genome editing system for the necrotrophic fungal plant pathogen Sclerotinia sclerotiorum. This system (the TrpC-sgRNA system), based on an RNA polymerase II (RNA Pol II) promoter (TrpC) to drive sgRNA transcription in vivo, was successful in creating gene insertion mutants. However, relatively low efficiency targeted gene editing hampered the application of this method for functional genomic research in S. sclerotiorum. To further optimize the CRISPR-Cas9 system, a plasmid-free Cas9 protein/sgRNA ribonucleoprotein (RNP)-mediated system (the RNP system) and a plasmid-based RNA polymerase III promoter (U6)-driven sgRNA transcription system (the U6-sgRNA system) were established and evaluated. The previously characterized oxaloacetate acetylhydrolase (Ssoah1) locus and a new locus encoding polyketide synthase12 (Sspks12) were targeted in this study to create loss-of-function mutants. The RNP system, similar to the TrpC-sgRNA system we previously reported, creates mutations at the Ssoah1 gene locus with comparable efficiency. However, neither system successfully generated mutations at the Sspks12 gene locus. The U6-sgRNA system exhibited a significantly higher efficiency of genemutation at both loci. This technology provides a simple and efficient strategy for targeted gene mutation and thereby will accelerating the pace of research of pathogenicity and development in this economically important plant pathogen.

This system (the TrpC-sgRNA system), based on an RNA polymerase II (RNA Pol II) promoter (TrpC) to drive sgRNA transcription in vivo, was successful in creating gene insertion mutants. However, relatively low efficiency targeted gene editing hampered the application of this method for functional genomic research in S. sclerotiorum. To further optimize the CRISPR-Cas9 system, a plasmid-free Cas9 protein/sgRNA ribonucleoprotein (RNP)-mediated system (the RNP system) and a plasmid-based RNA polymerase III promoter (U6)-driven sgRNA transcription system (the U6-sgRNA system) were established and evaluated. The previously characterized oxaloacetate acetylhydrolase (Ssoah1) locus and a new locus encoding polyketide synthase12 (Sspks12) were targeted in this study to create loss-of-function mutants. The RNP system, similar to the TrpC-sgRNA system we previously reported, creates mutations at the Ssoah1 gene locus with comparable efficiency. However, neither system successfully generated mutations at the Sspks12 gene locus. The U6-sgRNA system exhibited a significantly higher efficiency of genemutation at both loci. This technology provides a simple and efficient strategy for targeted gene mutation and thereby will accelerating the pace of research of pathogenicity and development in this economically important plant pathogen.

abstract	We previously reported on a CRISPR-Cas9 genome editing system for the necrotrophic fungal plant pathogen Sclerotinia sclerotiorum. This system (the TrpC-sgRNA system), based on an RNA polymerase II (RNA Pol II) promoter (TrpC) to drive sgRNA transcription in vivo, was successful in creating gene insertion mutants. However, relatively low efficiency targeted gene editing hampered the application of this method for functional genomic research in S. sclerotiorum. To further optimize the CRISPR-Cas9 system, a plasmid-free Cas9 protein/sgRNA ribonucleoprotein (RNP)-mediated system (the RNP system) and a plasmid-based RNA polymerase III promoter (U6)-driven sgRNA transcription system (the U6-sgRNA system) were established and evaluated. The previously characterized oxaloacetate acetylhydrolase (Ssoah1) locus and a new locus encoding polyketide synthase12 (Sspks12) were targeted in this study to create loss-of-function mutants. The RNP system, similar to the TrpC-sgRNA system we previously reported, creates mutations at the Ssoah1 gene locus with comparable efficiency. However, neither system successfully generated mutations at the Sspks12 gene locus. The U6-sgRNA system exhibited a significantly higher efficiency of genemutation at both loci. This technology provides a simple and efficient strategy for targeted gene mutation and thereby will accelerating the pace of research of pathogenicity and development in this economically important plant pathogen.
