Still time to apply: Postdoc position in our lab together with @meauxjuliette.bsky.social to combine Ecological models with quantitative genetics. Become part of a great community of Ecological Genetics. jobportal.uni-koeln.de/ausschreibun...

Now online in #GENETICS with @genetics-gsa.bsky.social : 'Adaptive Dynamics of Quantitative Traits in a Steadily Changing Environment'. Integrating theory and forward-in-time simulations to understand quantitative trait evolution. Was inspiring to collaborate with my awesome physics colleagues.

Was seed color in early crops really chosen for aesthetics? White seeds evolved repeatedly-not because humans preferred them, but because losing pigmentation reduced seed dormancy. Ecology, not intention, may have driven domestication. www.biorxiv.org/content/10.6... #PlantScience #Domestication

New preprint from the lab! Ella Ludwig assembled the first pangenome for grain amaranth and Tom mapped the genetic control of flowering time. Together it looks a lot like an insertion changing flowering time. If you are at #PAG don't miss Ella's talk on this! www.biorxiv.org/content/10.6...

The grain amaranth pangenome reveals domestication-associated changes in diversity and function of structural variationBackground: Grain amaranth is a nutritious pseudocereal from the Americas that was independently domesticated three times from a common wild ancestor. The three domesticated grain amaranths, their wil...www.biorxiv.org

TWO positions open in our group. 1 postdoc and 1 PhD position. Join us for some exciting evolutionary plant biology! #PlantSciJobs #PlantSciJob

Now out in its final version: 'Domestication shaped the chromatin landscape of grain amaranth' www.nature.com/articles/s41...

Domestication shaped the chromatin landscape of grain amaranth - Nature CommunicationsThe interplay between the chromatin landscape and plant domestication remains unclear. Here, the authors report the genome assembly and chromatin landscape map of amaranth and reveal the association b...www.nature.com

Sad to miss #ESEB2025, but check out work from our lab. The poster of Tom Winkler (P01.272) on repeated evolution under ecological selection during domestication tonight. And the talk of Margarita Takou on the detection of polygenic selection from time series data on Tuesday 15:30.

If you’re at #SMBE2025 and want to know how polygenic adaptation to different environmental change scenarios proceeds, go see PhD student Yuna Zhang from my lab presenting today 17:10-17:15 in Symposium 22 #quantgen

How can climate distribution models help to harness crop diversity? We look at recent advances in grain amaranth genomics and breeding to suggest how leveraging genetic diversity of underutilized crops could contribute to resilient and sustainable cropping systems. link.springer.com/article/10.1...

Assessing and mining grain amaranth diversity for sustainable cropping systems - Theoretical and Applied GeneticsGlobal challenges and new demands require adaptation of cropping systems. Plant genetic diversity can contribute to adapt and improve crops and create more sustainable agricultural systems. In order t...link.springer.com

Now published. Led by Dr. Akanksha Singh, we studied what happened to grain amaranth once it arrived to India. Surprisingly differentiation stayed high and populations adapted individually. No gene flow, high diversity.

Domestication shaped the chromatin landscape of grain amaranthPlant domestication has had profound impacts on the morphology and genetic diversity of crops. Beyond sequence diversity, changes in chromatin structure can play an important role in plant adaptation....www.biorxiv.org

I’m very happy to share that I will start as associate professor for plant ecological genomics at the University of Cologne in January 2024. Huge thanks to my great team, mentors, collaborators and everyone who helped to make this happen!
