Our latest work from led by the one and only @zoebernasconi.bsky.social reporting on a decoy-based pathogen recognition by wheat tandem kinases. Check it out! 🌱 🦠 🔬🧬
Check out our new pre-print! ✨
We cloned AvrWTK4, the first wheat powdery mildew effector recognised by a tandem kinase protein, and show that an HMA-like integrated domain in WTK4 acts as pathogen decoy. Discover the whole story on bioRxiv ⬇️

@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.
