*subTIR of D. mojavensis is from the 5' side; the 3' subTIR has a single mismatch (Figure 2). ^†Number of hits found by BLAST search using block A consensus of DINE-1 of each species. Only hits > 100 bp in length were included. ^‡Means (and standard deviations (STD) in parentheses) of percentage identity between the DINE-1 consensus to all BLAST hits of block A.
