Figure 3.

The nucleotide substitution that occurs between Arabidopsis and A. lyrata in ARF10. The ARF10 binding site is portrayed 5′ → 3′, whereas the sequence for miR160, which targets ARF10, is presented 3′ → 5′. The variable position is colored gray and marked by a box. Complementary positions (i.e. nonmismatches or gaps) are depicted with black lines. G:U mismatch positions, which may contribute to miRNA-target binding, are marked with a black circle. Note pairing symbols are based on major allele states.
