TEs aren’t just genomic parasites, they’re also engines of genomic novelty.
Our new study with ~2,000 Z. tritici genomes shows repeated TE mobilization waves during global expansion.

Historic transposon mobilisation waves create distinct pools of adaptive variants in a major crop pathogen - Nature Communications
In this study, the authors analysed a large genomic dataset to trace how jumping genes shaped the global spread of a major wheat pathogen and reveal bursts of activity over decades that drove adaptati...

1/ Ever needed to annotate TEs in a fungal genome, but didn't know where to start?
We have released #MycoMobilome, a community-focused non-redundant database of transposable element consensus sequences for the fungal kingdom, constructed from >4,000 fungal genomes!
