Stress-driven transposable element de-repression dynamics and virulence evolution in a fungal pathogen

S Fouché, T Badet, U Oggenfuss… - Molecular biology …, 2020 - academic.oup.com
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

SM Tralamazza, LO Rocha, U Oggenfuss… - Genome biology and …, 2019 - academic.oup.com
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

T Badet, U Oggenfuss, L Abraham, BA McDonald… - BMC biology, 2020 - Springer
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 …

[HTML][HTML] Genome evolution in fungal plant pathogens: looking beyond the two-speed genome model

DE Torres, U Oggenfuss, D Croll, MF Seidl - Fungal Biology Reviews, 2020 - Elsevier
The interaction of pathogens with their hosts creates strong reciprocal selection pressures.
Pathogens often deploy an arsenal of small proteins called effectors that manipulate the plant …

[HTML][HTML] Recent transposable element bursts are associated with the proximity to genes in a fungal plant pathogen

U Oggenfuss, D Croll - PLoS Pathogens, 2023 - journals.plos.org
The activity of transposable elements (TEs) contributes significantly to pathogen genome
evolution. TEs often destabilize genome integrity but may also confer adaptive variation in …

A devil's bargain with transposable elements in plant pathogens

S Fouché, U Oggenfuss, E Chanclud, D Croll - Trends in Genetics, 2022 - cell.com
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

U Oggenfuss, T Badet, T Wicker, FE Hartmann… - Elife, 2021 - elifesciences.org
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

L Stalder, U Oggenfuss, N Mohd‐Assaad… - Molecular …, 2023 - Wiley Online Library
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 …

Population-level transposable element expression dynamics influence trait evolution in a fungal crop pathogen

LN Abraham, U Oggenfuss, D Croll - Mbio, 2024 - Am Soc Microbiol
The rapid adaptive evolution of microbes is driven by strong selection pressure acting on
genetic variation. How adaptive genetic variation is generated within species and how such …

[HTML][HTML] Population genomics of transposable element activation in the highly repressive genome of an agricultural pathogen

D Pereira, U Oggenfuss, BA McDonald… - Microbial …, 2021 - microbiologyresearch.org
The activity of transposable elements (TEs) can be an important driver of genetic diversity
with TE-mediated mutations having a wide range of fitness consequences. To avoid …
