Evolution of piRNA-guided defense against transposable elements
Transposable elements (TEs) shape every aspect of genome biology, influencing genome
stability, size, and organismal fitness. Following the 2007 discovery of the piRNA defense …

Double trouble: two retrotransposons triggered a cascade of invasions in Drosophila species within the last 50 years
Horizontal transfer of genetic material in eukaryotes has rarely been documented over short
evolutionary timescales. Here, we show that two retrotransposons, Shellder and Spoink …

GenomeDelta: detecting recent transposable element invasions without repeat library
We present GenomeDelta, a novel tool for identifying sample-specific sequences, such as
recent transposable element (TE) invasions, without requiring a repeat library. GenomeDelta …

Spoink, a LTR retrotransposon, invaded D. melanogaster populations in the 1990s
During the last few centuries D. melanogaster populations were invaded by several
transposable elements, the most recent of which was thought to be the P-element between …

Rapid evolution of promoters from germline-specifically expressed genes including transposon silencing factors
Background The piRNA pathway in animal gonads functions as an 'RNA-based immune
system', serving to silence transposable elements and prevent inheritance of novel invaders …

Traffic Jam activates the Flamenco piRNA cluster locus and the Piwi pathway to ensure transposon silencing and Drosophila fertility.
Flamenco (Flam) is the most prominent piRNA cluster locus expressed in Drosophila
ovarian follicle cells, and it is required for female fertility to silence gypsy/mdg4 transposons …

Unistrand piRNA clusters are an evolutionarily conserved mechanism to suppress endogenous retroviruses across the Drosophila genus
Abstract The PIWI-interacting RNA (piRNA) pathway prevents endogenous genomic
parasites, ie transposable elements, from damaging the genetic material of animal gonadal …
