Application of CRISPR/CasΦ2 System for Genome Editing in Plants.

Abstract excerpt

CRISPR/Cas system has developed a new technology to modify target genes. In this study, CasΦ2 is a newly Cas protein that we used for genome modification in Arabidopsis and tobacco. PDS and BRI1 of marker genes were chosen for targeting. CasΦ2 has the function to cleave pre-crRNA. In the presence of 10 mM Mg2+ irons concentration, sgRNA3 type guided CasΦ2 to edit target gene and generate mutation, and a mutant...
