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...

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.

TEtrimmer: a tool to automate the manual curation of transposable elements - Nature Communications Transposons are repetitive DNA sequences that are hard to identify and map accurately. TEtrimmer automates key manual steps, enabling faster and more reliable annotation of transposable elements in any genome.

Some highlights:
- fully sequenced and annotated genomes of two species, including transposon space using #TEtrimmer for the first time in newly sequenced genomes www.nature.com/articles/s41...
- cultured Arachnopeziza in vitro
- confirmed selective fungicides
- expressed hygromycin resistance +RFP

Saprotrophic Arachnopeziza Species as New Resources to Study the Obligate Biotrophic Lifestyle of Powdery Mildew Fungi Obligate biotrophic plant pathogens like the powdery mildew fungi commit to a closely dependent relationship with their plant hosts and have lost the ability to grow and reproduce independently. Thus....

Genetic modification of obligate biotrophic pathogens like #powderymildew is often not possible, in part because they cannot be grown without a host.

We took a detour and established Arachnopeziza, closest extant relative of powdery mildew, as substitute!

Thrilled to share that our TEtrimmer paper has just been published in Nature Communications! A big thank you to all collaborators — the article is now online ;)
