I am happy to announce the launch of a new Arabidopsis genomics resource! Check out arabidopsislyrata.org Now you can easily look at the natural genetic variation across the entire species range of A. lyrata and A. arenosa.

The genetic and geographic origin of Arabidopsis suecica.

Diploid origins and early genome stabilization in the allotetraploid Arabidopsis suecica

Multiple Autopolyploid Arabidopsis lyrata Populations Stabilized by Long-Range Adaptive Introgression Across Eurasia Abstract. Abundance of established polyploid lineages varies across lineages, evolutionary time, and geography, suggesting both genetics and environment pl

@alisondawnscott.bsky.social et al. use genome data from >400 Arabidopsis lyrata sampled across Eurasia to show it as the most polyploid-rich species complex in Arabidopsis, with multiple origins of autotetraploidy.

🚨 My first PhD preprint is out on bioRxiv!
We show how tiny mutations—point mutations and kb-level indels—can shape the massive structure of Arabidopsis centromeres.

Me presenting

Can’t believe that was my last PhD retreat. It was fun showing off my genomes — but finishing a PhD? I’m not ready.

Cologne Spring Meeting was so much fun. I was happy to see everyone and finally present some progress on North American Arabidopsis lyrata selfers.
