Are you interested in learning how genomes of weird fungi and protists evolve and are you looking for an exciting PhD opportunity? Jolien van Hooff and I are looking for an enthusiasic PhD candidate at Wageningen University: www.wur.nl/en/vacancy/p... #TEworldwide #Fungi #Protists #Genome

PhD position in genome evolution and architecture in unicellular eukaryotes
Are you fascinated by how eukaryotic genomes evolve? Do you want to look beyond model organisms and point mutations to uncover the complexity of genome evolution?

The narrowing prokaryote–eukaryote divide reveals a complexity spectrum
Cellular organisms can be divided into two basic types of cells: the prokaryotic cells of Bacteria and Archaea and the eukaryotic cells. The rapidly expanding knowledge of the diversity and ultrastructure of prokaryotic cells has revealed cellular intricacies that warrant a critical reappraisal of the profundity of the prokaryote–eukaryote divide.

I am happy to share that my NWO Veni project was awarded 🍄🧬🔻! In this project, I will study how transposons shape genome folding, evolution, and adaptation in a fungal salamander pathogen. I am incredibly thankful for all the support and look forward to this next chapter #fungi #transposons #TEsky
A sketch of two salamander species, with a zoomed in picture of a fungal fruit body releasing spores, leading to a small stretch of DNA which ends in a folded chromosome with many green triangles indicating transposon insertions

Our paper "Gene ancestries reveal diverse microbial associations during eukaryogenesis.” is finally out in Nature. Eukaryogenesis was likely a gradual process shaped by multiple microbial partners and virus-mediated gene transfer, rather than a single binary symbiosis. doi.org/10.1038/s415...
