Comparative Genomics of Unicellular Eukaryotes (San Feliu, Spain): Abstract submission is open, with a short deadline! comparativegenomics2026.com Join us as we explore the most diverse, surprising, and still largely uncharted branches of the eukaryotic tree.

I've seen fossils in some remarkable places, but this takes the prize: the benthic foram Nummulites in the base of the Great Pyramid of Giza. These massive blocks were quarried from the Eocene Mokkatam Formation when a relictual population of woolly mammoths still lived on Wrangel Island.

New preprint out! Using ~75k environmental OTUs + 77 fossil calibrations, we reconstructed a Proterozoic timeline of eukaryote evolution. Our results show crown eukaryotes were already diversifying >1.6 Ga, long before the first undisputed fossils (~1.05 Ga). 🔗 DOI: www.biorxiv.org/content/10.6...

Extensive horizontal transfer of transposable elements shapes fungal mobilomes

Romeijn et al. reveal that horizontal transposon transfer is widespread in fungi, contributing up to 70% of transposon content in some taxa. The authors uncover thousands of events across diverse line...

Josje Romeijn@jromeijn.bsky.social · last yr.

The first paper of my PhD is now available as a preprint! 🎉 Transposable elements (TEs) don't just jump within fungal genomes, they also move extensively between species. In this study, we screened over 1,300 fungal genomes and found a conservative estimate of 5,500+ horizontal transfer events.

Those interested in performing maximum likelihood phylogenomic analysis on data sets made up of eukaryotic nuclear genes using site heterogeneous mixture models like C60, I suggest you use the ELM model in IQ-TREE instead of the LG model /1
