Host-induced fungal CAZymes act as disease determinants and drive multihost compatibility.

To cause rice blast disease, the filamentous fungus Magnaporthe oryzae develops a specialised infection cell called an appressorium, which generates enormous turgor to breach the rice leaf cuticle. Al...

Fungal effectors may have evolved from ancient antimicrobials, shaping plant microbiota and immunity during infection.

Background Throughout their life cycle, plants associate with diverse and complex microbial communities collectively known as their microbiota. These microbiota contribute to plant performance and hea...

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...

Evolutionary histories of effector proteins secreted by fungal pathogens to mediate plant colonization remain largely elusive. While most functionally characterized effectors modulate plant immunity, ...

Plants host diverse microbiota that influence physiological processes and can enhance resilience against invading pathogens that, in turn, evolved effector proteins to manipulate host microbiota in th...

Lipids play crucial roles in plant–microbe interactions, functioning as structural components, signaling molecules, and microbe-associated molecular patterns (MAMPs). However, the mechanisms underly...

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.
