According to the fact that a paddy rice BADH2 gene is designed based on a sgRNA sequence of CRISPR/Cas9, a DNA fragment with the sgRNA sequence coded is connected to a carrier carrying CRISPR/Cas, and paddy rice is transformed, thereby achieving site-directed mutagenesis … 2020-8-17 · It shows superior editing efficiencies compared to existing CRISPR/Cas protocols for filamentous fungi, and leads to a very low number of additional off-target mutations. To demonstrate the performance of our protocol, we conducted for the first time a site-directed, random mutagenesis in a gene encoding an important fungicide target. The CRISPR/Cas system has been applied in genome editing across multiple plant species, including model plants (see, e.g. Jiang et al. , Li et Site‐directed mutagenesis; In this Opinion, a molecular biology method that is used to make specific and intentional changes (insertions, deletions and substitutions) to a genomic locus 2019-4-30 · Butt and colleagues designed a CRISPR/Cas-directed evolution platform in which a library of all possible sgRNAs for a target gene was used. Rice Splicing Factor 3b subunit 1 (OsSF3B1) was chosen as a target gene for directed evolution because it is conserved among eukaryotes and is essential for RNA splicing.In human, SF3B1 is targeted by splicing inhibitors such as herboxidiene (GEX1A) and 2020-12-29 · Site directed single nucleotide mutagenesis still has good utility and compares favorably to CRISPR/Cas9 for very small edits, but it is rather impractical from a time, resources and cost perspective for larger edits.

Key message Site-directed mutagenesis of nitrate reductase genes using direct delivery of purified Cas9 protein preassembled with guide RNA produces mutations efficiently in Petunia × hybrida protoplast system. Abstract The clustered, regularly interspaced, short palindromic repeat (CRISPR)-CRISPR associated endonuclease 9 (CRISPR/Cas9) system has been recently announced as a powerful The generation of genetic mutants in Caenorhabditis elegans has long relied on the selection of mutations in large-scale screens. Directed mutagenesis of specific loci in the genome would greatly speed up analysis of gene function. Here, we adapt the CRISPR/Cas9 system to generate mutations at specific sites in the C. elegans genome. Here we describe a method for robust directed evolution using mutagenesis of large sequence spaces in their genomic contexts. The method employs error-prone PCR and Cas9-mediated genome integration of mutant libraries of large-sized donor variants into single or multiple genomic sites with efficiencies reaching 98–99%.
