Undermining the cry for help: the phytopathogenic fungus Verticillium dahliae secretes an antimicrobial effector protein to undermine host recruitment of antagonistic Pseudomonas bacteria During pathogen attack, plants recruit beneficial microbes in a ‘cry for help’ to mitigate disease development. Simultaneously, pathogens secrete effectors to promote host colonisation through vario...

Plant-associated fungi co-opt ancient antimicrobials for host manipulation Evolutionary histories of effector proteins secreted by fungal pathogens to mediate plant colonization remain largely elusive. While most functionally characterized effectors modulate plant immunity, ...

📣 NEW PREPRINT 📝

We identified evolutionary origins of many fungal effectors!
We show that fungi secrete lots of antimicrobial proteins, and that some of them were repurposed by plant pathogens for host immune suppression.

Time to move on!

Heading to Zürich🇨🇭 where I will join the group of @mvanderheijden.bsky.social for my second post-doc.

I am very thankful for my time with @teamthomma.bsky.social at the University of Cologne. I learned a lot and cannot wait to share more of our findings soon.

So long Köln…

Starship giant transposons dominate plastic genomic regions in a fungal plant pathogen and drive virulence evolution Starships form a recently discovered superfamily of giant transposons in Pezizomycotina fungi, implicated in mediating horizontal transfer of diverse cargo genes between fungal genomes. Their elusive nature has long obscured their significance, and their impact on genome evolution remains poorly understood. Here, we reveal a surprising abundance and diversity of Starships in the phytopathogenic fungus Verticillium dahliae. Remarkably, Starships dominate the plastic genomic compartments involved in host colonization, are enriched in virulence-associated genes, and exhibit genetic and epigenetic characteristics associated with adaptive genome evolution. We further uncover extensive horizontal transfer of Starships between Verticillium species and, strikingly, from distantly related Fusarium fungi. Finally, we demonstrate how Starship activity facilitated the de novo formation of a novel virulence gene. Our findings illuminate the profound influence of Starship dynamics on fungal genome evolution and the development of virulence. ### Competing Interest Statement The authors have declared no competing interest.

📣New year, new preprint @biorxiv-microbiol.bsky.social 🎉! A study led by the brilliant @yukiyosato.bsky.social showing that Starship giant transposons dominate plastic genomic regions in the fungal plant pathogen Verticillium dahliae and drive virulence evolution. 🧵[1/12] doi.org/10.1101/2025...
