^aInsertion site is defined as the number of base pairs from the closest end of the target element to the first nucleotide of the TIR of the insertion element.

^bElements that form trimers. The numbers in parentheses indicate the order of insertion. Element 1 is the first preexisting element; element 2 is the element that inserted into element 1; element 3 is the element that inserted into element 2.

^cRIL represents recombinant inbred lines from the B73 × Mo17 cross.
