How consistent are signatures of #adaptation between independent yet related pops? 🧬
Our new study in Mol Ecol uses #topography to explain genomic var in 4 alpine pops of Arabis alpina at local and regional extents for #SNPs & #TEs πŸŒ±β›°οΈ

A systematic screen for genetic factors underpinning transposon defense systems across the fungal kingdom Fungal genome sizes exhibit more than a 100-fold variation, largely driven by the expansion of repetitive sequences such as transposable elements (TEs). Genomic defenses have evolved to counteract TE ...

Summary slide showing how the giant transposon "Chrysaor" (Centre) confers resistance to high concentrations of formalin in both Paecilomyces variotii (bottom right) and Aspergillus fumigatus (Bottom left). Phylogenies (Top left) and whole genome comparisons (Top right) indicate that Chrysaor has been horizontally transferred between these species.

The final version of our latest Starship manuscript is out!πŸš€We study the evolution of a gene cluster for formaldehyde resistance to show that #HGT mediated by giant Starship #transposons is a recurrent force in #fungal adaptation.

Representing Swiss Research in beautiful Perth πŸ‡¨πŸ‡­πŸ‡¦πŸ‡Ί
Shared our journey exploring centromeric transposable elements at #AusEvol2024! 🌿

Our research unveils the interplay between specialized centromeric TEs and how their "escape" across chromosomes reshapes the functional genome.

Paper coming soon πŸ€“
