Retrotransposons in the flanking regions of normal plant genes: a role for copia-like elements in the evolution of gene structure and expression.
Open accessAbstract
The wx-K mutation results from the insertion of a copia-like retrotransposon into exon 12 of the maize waxy gene. This retrotransposon, named Hopscotch, has one long open reading frame encoding all of the domains required for transposition. Computer-assisted database searches using Hopscotch and other plant copia-like retroelements as query sequences have revealed that ancient, degenerate retrotransposon insertions are found in close proximity to 21 previously sequenced plant genes. The data suggest that these elements may be involved in gene duplication and the regulation of gene expression. Similar searches using the Drosophila retrotransposon copia did not reveal any retrotransposon-like sequences in the flanking regions of animal genes. These results, together with the recent finding that reverse-transcriptase sequences characteristic of copia-like elements are ubiquitous and diverse in plants, suggest that copia-like retrotransposons are an ancient component of plant genomes.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
