Historic transposon mobilisation waves create distinct pools of adaptive variants in a major crop pathogen - Nature Communications In this study, the authors analysed a large genomic dataset to trace how jumping genes shaped the global spread of a major wheat pathogen and reveal bursts of activity over decades that drove adaptati...

TEs aren’t just genomic parasites, they’re also engines of genomic novelty.

Our new study with ~2,000 Z. tritici genomes shows repeated TE mobilization waves during global expansion.

Thanks a lot Isa @isabelmonte.bsky.social👩‍🔬for accepting our invitation🤩. Such a terrific talk, opening up new research lines hand-in-hand with #Trichoderma. MPMI in its purest state!!! Special thanks to @agrienvironcyl.bsky.social for funding the visit, and many more yet to come. 🌿🧫🦠🧬

Dual recognition of structurally unrelated mildew effectors underlies the broad-spectrum resistance of Pm3e in wheat Broad-spectrum resistance genes are highly valuable for sustainable crop protection, yet the molecular basis of their activity is often unknown. The Pm3 allelic series in wheat encodes NLR receptors t...

Just back from #2025ISMPMI and #SEFIMEC2025, where we shared first results from the @cienciagob.bsky.social -funded TANGO project PID2022-142651OA-I00 . Great discussions, fresh insights and exciting new ideas! 🌱🔬🧪Kudos to David Encalada Bustamante...and none of it possible w/o @vwidrig.bsky.social

Thrilled to share our latest preprint! This work started during my PhD and was finished together with @jmadhuprakash.bsky.social. We found a Phytophthora infestans L-shaped effector that bridges a host TOL protein to activated NLRs to suppress immunity!

Virulence on Pm4 kinase-based resistance is determined by two divergent wheat powdery mildew effectors The wheat resistance gene Pm4 encodes a kinase fusion protein and has gained particular attention as it confers race-specific resistance against two major wheat pathogens: powdery mildew and blast.

Fungal phylogeny highlighting genome size changes

Summary of genome size variation among groups

@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.
