By redirecting the editing enzymes from the cytoplasm to the nucleus, off-target editing is reduced without compromising the on-target editing efficiency.

WebbThe use of a Cas9 nickase will minimize off-target damage. The Cas9 nickases only cut one strand but can still target a genome edit. However, an off-target nick, relative to a double-stranded break, is easier to accurately repair. There are also modified Cas9 proteins that offer higher specificity than wild type. The terminology is confusing. WebbCRISPR-Cas-based genome editing allows for precise and targeted genetic modification of plants. Nevertheless, unintended off-target edits can arise that might confer risks when present in gene-edited food crops. Through an extensive literature review we gathered information on CRISPR-Cas off-target edits in plants.
