| PubMed Abstract |
Copy numbers of sequences homologous to the Drosophila melanogaster retrotransposable element 412, their distribution between
the chromosome arms and the chromocenter, and whether they contain full-size copies were analyzed for 55 species of the Drosophila
genus. Element 412 insertion sites were detected on the chromosome arms of D. melanogaster, Drosophila simulans, and a few
species of the obscura group, but the chromocenter was labeled in almost all species. The presence of element 412 sequences
in the majority of species shows that this element has a long evolutionary history in Drosophilidae, although it may have
recently invaded the chromosomes in some species, such as D. simulans. Differences in copy number between species may be due
to population size or specific endogenous or environmental factors and may follow the worldwide invasion of the species. Putative
full-length copies were detected in the chromocenters of some species with no copies on the chromosome arms, suggesting that
the chromocenter may be a shelter for such copies and not only for deleted ones.
