P transposable elements are one of the best‐studied eukaryotic mobile DNA elements in
metazoans. These elements were initially discovered in the late 1960's because they cause …

▪ Abstract Transposable elements propagate by inserting into new locations in the genomes
of the hosts they inhabit. Their transposition might thus negatively affect the fitness of the …

There is strong inferential evidence for recent horizontal gene transfer of the P (mobile)
element to Drosophila melanogaster from a species of the Drosophila willistoni group. One …

Molecular and genetic analysis has revealed a specific P factor deletion derivative (the KP
element) which is able to repress P‐induced hybrid dysgenesis. All naturally occurring …

In a classic example of the invasion of a species by a selfish genetic element, the P-element
was horizontally transferred from a distantly related species into Drosophila melanogaster …

Drosophila P transposable elements encode two proteins, an 67 kd transposase proteln and
a 66 kd protein that has been hypothesized to repress transposition. We have made …

Two P elements, inserted at the cytological site 1A on an X chromosome from an Drosophila
melanogaster natural population (Lerik, USSR), were isolated by genetic methods to …

Transposable elements (TEs) are repeated DNA sequences that can constitute a substantial
part of genomes. Studying TEs' activity, interactions, and accumulation dynamics is thus of …

Transposable elements (TEs) are virtually ubiquitous components of genomes, yet they
often impose significant fitness consequences on their hosts. In addition to producing …

The Tc1 transposable element family of the nematode Caenorhabditis elegans consists
primarily of 1.6-kb size elements. This uniformity of size is in contrast to P in Drosophila and …
