@article {73673, title = {Tos17 rice element: incomplete but effective.}, journal = {Mobile DNA}, volume = {5}, year = {2014}, month = {2014}, pages = {10}, abstract = {BACKGROUND: Tos17 was the first LTR retrotransposon (Copia) described as active in cultivated rice, and is present in two copies in the genome of the sequenced Nipponbare variety. Only the chromosome 7 copy is active and able to retrotranspose, at least during in vitro culture, and this ability was widely used in insertional mutagenesis assays. RESULTS: Here the structure of the active Tos17 was thoroughly annotated using a set of bioinformatic analyses. CONCLUSIONS: Unexpectedly, Tos17 appears to be a non-autonomous LTR retrotransposon, lacking the gag sequence and thus unable to transpose by itself.}, issn = {1759-8753}, doi = {10.1186/1759-8753-5-10}, author = {Sabot, Fran{\c c}ois} }
