Insertion site sequences. (A) Target sequence logos. Arrow indicates the position of 3' insertion site. Sample numbers are represented at upper right. As insertions with 20-bp target site duplications (TSDs) are not included, the sums of sample numbers are not equal to those in Tables 2 and 3. (B) An example of short TSDs that were likely to be parts of long TSDs including substitution. TSDs are underlined and identical sequences in TSDs are shaded in black.
