This study identifies retrotransposon proliferation as a driver of genome size expansion in Pseudocercospora species, with species-specific TE families and ongoing activity in some strains.

The paper identifies transposable elements and repeat-induced point mutation as triggers of chromosomal instability and degeneration in a fungal pathogen through experimental progeny analysis.

The paper identifies Starships as vectors for horizontal transfer of transposable elements (TEs) in fungi, showing their role in TE bursts and genome structural changes.

The paper examines TE expression dynamics in a fungal pathogen, finding that TE activity influences trait variation and adaptation.

The paper identifies recent transposable element bursts in Zymoseptoria tritici genomes triggered by insertions near genes and GC-rich niches, revealing how genomic features influence TE proliferation.

The paper tracks transposable element (TE) expansion in Zymoseptoria tritici populations, showing that demographic factors and relaxed selection drive genome size increases.

The paper analyzes TE activity in Parastagonospora nodorum using population genomics, finding recent TE activation despite RIP defenses and purifying selection maintaining low insertion frequencies.

The paper constructs a high-quality pangenome for Zymoseptoria tritici using 19 genomes, revealing extensive gene presence-absence variation and its functional implications.

The paper analyzes gene cluster diversity in Fusarium fungi, identifying processes like horizontal transfer and transposable element-driven rearrangements that shape specialized metabolite production.

The paper investigates how different stress conditions affect transposable element (TE) expression in the fungal pathogen Zymoseptoria tritici, revealing distinct TE de-repression patterns and the influence of genetic background and genomic context.
