Figure 1

Target site preference of PIF and mPIF elements. (a) Six PIF elements inserted independently into exactly the same position in the second intron of the maize R gene (16). Triangles represent PIF TIRs and black rectangles represent exons 2 and 3 of R. (b) Consensus extended target site derived from a comparison of the sequences flanking 30 mPIF elements. (c) Consensus extended target site derived from a comparison of the sequences flanking 14 PIF elements. Gray rectangles indicate the trinucleotide duplicated on element insertion (the TSD). Numbers represent the percentage of times that a nucleotide appeared at that position.
