Highly Efficient CRISPR-Associated Protein 9 Ribonucleoprotein-Based Genome Editing in Euglena gracilis

Genome editing in maize directed by CRISPR–Cas9 ribonucleoprotein complexes

Targeted DNA double-strand breaks have been shown to significantly increase the frequency and precision of genome editing. In the past two decades, several double-strand break technologies have been developed. CRISPR-Cas9 has quickly become the technology of choice for genome editing due to its simplicity, efficiency and versatility. Currently, genome editing in plants primarily relies on deliv...

Efficient Mitochondrial Genome Editing by CRISPR/Cas9

The Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)/Cas9 system has been widely used for nuclear DNA editing to generate mutations or correct specific disease alleles. Despite its flexible application, it has not been determined if CRISPR/Cas9, originally identified as a bacterial defense system against virus, can be targeted to mitochondria for mtDNA editing. Here, we show t...

Efficient DNA-free genome editing of bread wheat using CRISPR/Cas9 ribonucleoprotein complexes

Substantial efforts are being made to optimize the CRISPR/Cas9 system for precision crop breeding. The avoidance of transgene integration and reduction of off-target mutations are the most important targets for optimization. Here, we describe an efficient genome editing method for bread wheat using CRISPR/Cas9 ribonucleoproteins (RNPs). Starting from RNP preparation, the whole protocol takes on...

Selection of highly efficient sgRNAs for CRISPR/Cas9-based plant genome editing.

The CRISPR/Cas9-sgRNA system has been developed to mediate genome editing and become a powerful tool for biological research. Employing the CRISPR/Cas9-sgRNA system for genome editing and manipulation has accelerated research and expanded researchers' ability to generate genetic models. However, the method evaluating the efficiency of sgRNAs is lacking in plants. Based on the nucleotide composi...
