Figure 2From: Plant genome editing made easy: targeted mutagenesis in model and crop plants using the CRISPR/Cas systemCas9 variants used for genome editing in plants. The Cas9 nuclease was expressed as a fusion protein with a tag (FLAG or GFP as indicated) under various constitutive promoters. Diagonal lines indicate an intron inserted into the Cas9 gene.
