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

Assessing and mining grain amaranth diversity for sustainable cropping systems - Theoretical and Applied Genetics Global 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...

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.

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.

Talking Biotech 459 - where did the key domestication mutations in corn come from? Were they present in resident gene pools waiting to be selected, or new mutations? I discuss with @jrossibarra and his student Regina Fairbanks.

Domestication had profound impacts on plant traits. But how about the shape of DNA? We find that more chromatin opened than closed during domestication and that selection signals overlap with chromatin changes.

Local Selection Shaped the Diversity of European Maize Landraces The introduction of populations to novel environments can lead to a loss of genetic diversity and the accumulation of deleterious mutations due to selection and demographic changes. We investigate ho...

Our work on selection and how it shaped the diversity of European maize landraces is now published. Read for diversity changes not following expansion routes but climatic gradients, & genetic load accumulation.
