Figure 1

Schematic drawing illustrating examples of genome editing assays in plants. The CRISPR/Cas9 technology was successfully applied in model plants (Nicotiana benthamiana, Arabidopsis thaliana) and crops (rice, wheat). The Cas9 nuclease and the sgRNA matching the gene of interest are co-expressed using Agrobacterium tumefaciens as a vector in N. benthamiana leaves or transfected into protoplasts from Arabidopsis, wheat or rice. Then, the genomic DNA is extracted from the leaf tissues or protoplasts and subject to PCR-amplification with primers flanking the target site. The presence of Cas9/sgRNA-induced mutations can be easily detected using the restriction enzyme (RE) site loss method. The RE-resistant band (lane 3) can be cloned. The exact nature of the mutations is then revealed by sequencing individual clones.
