The first paper of my PhD is now available as a preprint! 🎉

Transposable elements (TEs) don't just jump within fungal genomes, they also move extensively between species. In this study, we screened over 1,300 fungal genomes and found a conservative estimate of 5,500+ horizontal transfer events.

Excited to share the first PhD preprint of @iglavincheska.bsky.social — now on bioRxiv!
We explored the 3D genome of Zymo and found:
🧬 Rabl-like conformation
🧩 Accessory chr tethered to core centromeres
🏰 Self-interacting domains and boundaries with insulator motifs

ℹ️ Deadline is set to May 23rd.

🔥 Many slots are still available.

And shoutout to the other members of the organising committee @oggenfussursula.bsky.social and @danielcroll.bsky.social

🔥 The event will bring together molecular biologists, evolutionary geneticists, and bioinformaticians to explore RIP’s role in transposable element control, genome integrity, and fungal adaptation.

Looking forward to seeing you in Neuchâtel! 🏔️ #RIPM2025 #FungalGenomics #EvolutionaryBiology

🔥 Exciting news! The first Symposium on Repeat-Induced Point mutations is happening June 30 – July 1 at the University of Neuchâtel🇨🇭!

@guidopuccetti.bsky.social, Gabriel Scalliet and I are excited to share our latest work.

Resistance in agriculture emerges fast, but we fail to grasp how the myriad mutations in pathogen populations contribute to this.

Please check out and share our latest preprint: www.biorxiv.org/content/10.1...

We did it! We caught Starship #transposons moving between #fungal species in the lab, including between species separated by ~100my. We think Starships are a mediator of HGT in fungi, akin to conjugative elements in bacteria. Check out the preprint. www.biorxiv.org/content/10.1...

Great talk @iglavincheska.bsky.social, exploring the impact of DNA methylation variation on the 3D genome structure of Zymoseptoria tritici!

Interested in #fungal accessory chromosomes or toxin/antidote genes? Check out our new preprint! We show that the Spok gene family in Fusarium include active toxin/antidote genes. We present a model for how these genes influence the evolution of fungal genomes. www.biorxiv.org/content/10.1...

This looks a fascinating read!

TEs at work.
Very interesting results.

@tbadet.bsky.social and I have a preprint out on transposon silencing in fungi!

Genome size evolution is fascinating and showcases the dynamic nature of transposon activation.

What we understand less are the dynamics of transposon defense systems encoded by the genomes.
