  1. 1Strong constitutive (Ubi promoter) or heat-shock (HS) expression
  2. 2 < 15 bp indel at the target without the loss of sequences immediately adjacent to the nuclease target
  3. 350–200 bp insertion or deletion
  4. 4No amplicons obtained in PCR
  5. 5No DSB-repair as indicated by PCR and/or sequencing
