  1. Note: 26 organisms were selected for in silico prediction of TALEN candidate editable genes and promoter regions. Promoter regions are defined as the 2 kb region upstream and downstream of genes. A N20-NGG sequence pattern is used to identify the CRISPR/Cas9 target sits. Then, these target sites are BLAST against both gene and promoter regions to eliminate off-target sites using strict criteria, where a candidate editable site is defined when only the seed region (12 bps adjacent to PAM) is unique.
  2. BLAST, Basic Local Alignment Search Tool; CRISPR, Clustered Regularly Interspaced Short Palindromic Repeats; PAM, protospacer adjacent motif; TALEN, Transcription Activator-Like Effector Nuclease.
