Structural homology reveals cerato-platanins as conserved antimicrobials repeatedly co-opted for fungal host colonization

Anton Kraege, Valentina Wolf, Fantin Mesny…·Bart P. H. J. Thomma

This study identifies antimicrobial activity as the conserved core function of fungal cerato-platanins, showing how these proteins evolved from ancient antimicrobials to manipulate host interactions.

A fungal pathogen effector that shapes host plant microbiota kills bacteria through lipoteichoic acid binding and membrane disruption

Gabriella C. Petti, Nick C. Snelders, Ashok Rout…·Bart P. H. J. Thomma

This paper identifies VdAve1, an antimicrobial effector from the fungal pathogen Verticillium dahliae, and shows it kills bacteria by binding lipoteichoic acid and disrupting plasma membranes.

A gnotobiotic system reveals multifunctional effector roles in plant-fungal pathogen dynamics

Wilko Punt, Jiyeun Park, Hanna Rövenich…·Bart P. H. J. Thomma

The paper develops a gnotobiotic system to study plant-fungal pathogen interactions, showing that specific effector proteins influence virulence and microbiota manipulation.
