Abstract: | Ty3/gypsy-type LTR-retrotransposons have been found only in lily and maize but not in cryptogam. In fernAdiantum, we recently found a full-lengthTy3/gypsy-type LTR-retrotransposon (ARET-1; 8284 bp). This retrotransposon has both 5′ and 3′ LTRs (1.2 kb), a primer binding site, a polypurine tract, and an RNA binding
motif and its domain arrangement in thepol region is the same as that ofTy3/gypsy-type retrotransposon. These results suggest thatTy3/gypsy-type retrotransposons are widespread among vascular plants.
The nucleotide sequence data reported will appear in the EMBL, DDBJ and GenBank Nucleotide Sequence Databases under the accession
number AB003364. |
