Table 2 Palindromes within sequences flanking the insertion site. We used the paldpl program to detect approximate palindromes of at least 3 bp with no more than 30% mismatches or indels. This analysis was done in native flanking sequences identified in plant genomes and their randomized (permutated) counterparts, to control for base content effects. We carried out a paired t-test for difference in calculated stem lengths of the native and randomized palindromes

From: Nested plant LTR retrotransposons target specific regions of other elements, while all LTR retrotransposons often target palindromes and nucleosome-occupied regions: in silico study
