Sequence homology between the apple transposon and other plant transposons. (A) The apple transposon (dem1) has a primer-binding site and polypurine tract similar to that of transposon in rice (rire3) and Lilium henryi (del1). (B) dem1 shears significant homology to the amino acid sequences in the reverse transcriptase domain of retrotransposons of pineapple (dea1) and L. henryi (del1). Eight stop codons were detected (shown as asterisks) in the apple transposon. The numbers indicate amino acid positions for dea1 (GenBank accession no. Y12432) and del1 (accession no. X13886) as previously published and nucleotide positions for dem1 as the sequence submitted to GenBank (accession no. AJ291492).
