Fig. 4: Verification of homozygous deletion mutant lines.

a Primer sets were used to amplify the editing regions between two DSBs in AP1, SVP, and TFL1 separately. b–d Agarose gel electrophoresis of the fragments of targeted genes. The absence of all three fragments indicated plants with homozygous deletions. WT wild type. e Efficiencies of targeted deletion with different mutation types in T1 plants
