Any point mutation can be introduced in vivo with the help of the CRISPR-CAS9 system into the genome of a model organism. Here, in the CRISPR-CAS9, the CAS9 is the nuclease which is used to cleave the DNA. The experiment results showed that the mutation rate is 72.73% in the T 0 transgenic lines (Table 1), the data indicated that the CRISPR/Cas9 system efficiently induced DSB in the ALC locus with CRISPR/Cas9-based site-directed mutagenesis in vivo was achieved using either the Cauliflower mosaic virus 35S or M. polymorpha EF1α promoter to express Cas9.

Crispr cas site directed mutagenesis

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%.
