Abstract

CRISPR/Cas9-based genome editing technology has been an important tool to study the gene function and genomic modification. Directed by a guide RNA, Cas9 protein can cleavage the genomic DNA at the target site, and produce mutations, including deletion, insertion, substitution and fragment deletion, by DNA double strand break (DSB) repair mechanism. In this protocol, we introduce the method to use CRISPR/Cas9 system to increase the efficiency of genomic DNA fragment deletion with microhomology-mediated end joining, especially the details in target design and detection of mutant plants.
