Transposable elements drive much of naturally occurring genetic lethality in Drosophila melanogaster Recessive lethal mutations are widespread across studied species, with estimates suggesting that each individual carries at least one. Numerous lethal alleles persist in wild populations at higher fre...

Rapid emergence of non-autonomous elements may stop P-element invasions in the absence of a piRNA-based host defence Author summary Transposable elements (TEs) are short, self-replicating DNA sequences found in nearly all genomes. While they can be harmful to their hosts, many organisms have evolved defence systems,...

Adaptive P-element insertions in a long non-coding RNA are associated with unique silencing properties Transposable elements are genetic parasites whose mobilization throughout the genome is a major source of deleterious mutations. However, some TE insertions are beneficial because they improve host fi...

Rapid emergence of hyperparasitic elements may stop P-element invasions in the absence of a piRNA-based host defence Transposable element (TE) invasions pose risks to both the TE and the host. All copies of a TE may be lost via genetic drift, or host populations may suffer fitness declines, potentially leading to ex...

Here, we demonstrate that Starships, a newly discovered group of cargo-mobilizing transposable elements, are active vectors of horizontally transferred DNA among eukaryotic species.
