Congratulations to @rpianezza.bsky.social @rokofler.bsky.social, Matt Beaumont and Sarah Saadain! We found an endogenous retro virus currently invading D. melanogaster!

The ongoing invasion of the endogenous retrovirus Kuruka in natural Drosophila melanogaster populations - Nature Communications
Transposable elements are mobile DNA sequences that can copy themselves and spread between species. This study finds that Kuruka, a retrovirus-like transposon, invaded Drosophila melanogaster within t...

The History of Transposable Element Invasions in Drosophila melanogaster
As a fundamental biological principle, genomic information is typically transmitted vertically from parent to offspring. Occasionally, however, genetic material is transferred horizontally between spe...

First day at #EMBOMobileGenome So many great talks! Toby’s on fungal genome evolution was a highlight: exciting results and inspiring questions ahead

We discovered an endogenous retrovirus that's still spreading in natural D. melanogaster populations! It was horizontally transferred from D. erecta in Central Africa, so we named it "Kuruka", which means "jump" in Swahili. Read its cool story here: www.biorxiv.org/content/10.1...

Germline defence from TEs largely relies on piRNAs. Yet, @divyaselvaraju.bsky.social and I monitored a P-element invasion in Drosophila that was stopped by an internally deleted copy, no host intervention required! doi.org/10.1371/jour...

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,...

The work on TE invasions in D. melanogaster continues! We found three more recent invasions, one of which occurred in ~3 years worldwide. Another great collaboration with @rpianezza.bsky.social @rokofler.bsky.social and others

Spatio-temporal tracking of three novel transposable element invasions in Drosophila melanogaster over the last 30 years
Abstract. Transposable elements (TEs) are repetitive sequences capable of mobilizing within genomes, exerting a sigfinificant influence on evolution throug

Our new preprint is out! We explored the biogeographic origins of TEs in the D. melanogaster genome. Most TEs were recently acquired via horizontal transfer, mainly from Afrotropical Drosophila species. Surprisingly, all African drosophilids share some of these TEs! www.biorxiv.org/content/10.1...

Biogeography shapes the TE landscape of Drosophila melanogaster
The abundance and composition of transposable elements (TEs) varies widely across species, yet the evolutionary forces shaping this diversity remain poorly understood. Using 285 recently published gen...
