New preprint reveals bacteria can't just collect all resistance genes like Pokemon cards.
We found mutually exclusive evolutionary pathways to multidrug resistance in E. coli & P. aeruginosa - some resistance mechanisms actively prevent others from coexisting www.biorxiv.org/content/10.1...

Genomic constraints shape the evolution of alternative routes to drug resistance in prokaryotes
Background Variation within the prokaryotic pangenome is not random, and natural selection that favours particular combinations of genes appears to dominate over random drift. What is less clear is wh...

Happy to share our latest preprint! We show that two Z. tritici effectors trigger necrosis in Nicotiana, and that ROS modulation by some effectors depends on the presence of a signal peptide. These findings highlight that effector function can go beyond predictions based only on expression profiles.

Exciting day travelling to Wageningen to examine the very impressive work of Anouk C. van Westerhoven, co-supervised by Gert H. J. Kema and @mfseidl.bsky.social!
Also, looking forward to get again dressed fancy in some borrowed gown 🎓😉

One week ago, I successfully defended my Ph.D. dissertation! I'm deeply grateful to my advisors, mentors, and all the amazing scientists whose insights and support shaped this journey. And of course, thanks to Zymoseptoria—such a fascinating fungus to study! ☺️

Very excited with @tobybarilbio.bsky.social to share this preprint about his latest work on TEs!
We knew that TEs were very pretty active in this global fungal pathogen of wheat.
Now with nearly 2000 Illumina genomes available, we could finally ask questions about historic TE activation waves.

Excited to share the latest issue of InterConnections from IS-MPMI, where I interview Dr. Achal Rastogi, who I met during my internship at Corteva. I learned a lot from his perspective and advice for the young scientists.

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...

HI old friends! Finally took the leap here to say I have several open positions going in my lab at the moment (and more to come).
1) PhD studentship in collaboration with the Royal Horticultural Society (genomics)
2) Biochemistry Postdoc to understand how Starships move
