Stress-driven transposable element de-repression dynamics and virulence evolution in a fungal pathogen
Transposable elements (TEs) are drivers of genome evolution and affect the expression
landscape of the host genome. Stress is a major factor inducing TE activity; however, the …

Complex Evolutionary Origins of Specialized Metabolite Gene Cluster Diversity among the Plant Pathogenic Fungi of the Fusarium graminearum Species Complex
Fungal genomes encode highly organized gene clusters that underlie the production of
specialized (or secondary) metabolites. Gene clusters encode key functions to exploit plant hosts …

[HTML][HTML] A 19-isolate reference-quality global pangenome for the fungal wheat pathogen Zymoseptoria tritici
Background The gene content of a species largely governs its ecological interactions and
adaptive potential. A species is therefore defined by both core genes shared between all …

A devil's bargain with transposable elements in plant pathogens
Transposable elements (TEs) spread in genomes through self-copying mechanisms and are
a major cause of genome expansions. Plant pathogens have finely tuned the expression of …

A population-level invasion by transposable elements triggers genome expansion in a fungal pathogen
Genome evolution is driven by the activity of transposable elements (TEs). The spread of
TEs can have deleterious effects including the destabilization of genome integrity and …

The population genetics of adaptation through copy number variation in a fungal plant pathogen
Microbial pathogens can adapt rapidly to changing environments such as the application of
pesticides or host resistance. Copy number variations (CNVs) are a major source of adaptive …
