Figure 3.

Overview of sources of genomic variation in crop plants. The simplified gene models depict observed variation among individual crop species. Comparison of inherent/standing (genotypes X and Y) and induced variation (by chemicals and irradiation) with the reference genome shows a range of intended and unintended mutations, including SNPs, small indels, transposon insertions/movement, or a large segmental deletion. However, the intended edit induced via a SDN occurs at the target site. Note that the diagram is not drawn to scale and that intergenic variation is not shown.
