Genomic offset analyses suggest that most populations are already well matched to projected future climates. Together, our results show how niche tracking and polygenic adaptation can promote persistence under environmental change. @molecology.bsky.social @novonordisk.bsky.social

We found environmental adaptation to be highly polygenic, with thousands of genomic regions associated with climatic, edaphic and agricultural variables. We also found limited environmental pleiotropy, suggesting a largely modular architecture of adaptation.

Combining 200 years of occurrence records with whole-genome data from contemporary populations across Europe, we show that blackgrass has largely maintained its historical niche, expanding primarily by tracking environments analogous to those occupied in the past.

New paper out! 🎉🎉 How does one of Europe's most damaging agricultural weeds respond to climate change? onlinelibrary.wiley.com/doi/10.1111/me… Over 200 years, blackgrass successfully tracked environmental change while maintaining the genomic variation needed to persist under future climates.

Latest in #GENETICS from @celianeto.bsky.social, @ahancock.bsky.social, and colleagues: A new panel of genetically diverse recombinant #Arabidopsis lines from the Cape Verde Islands uncovers genetic variants of adaptation that were difficult to map in this island population. 🌱 🏝️ 🔗 buff.ly/oOTp4hV

This new intercross population provides a complementary resource for dissecting the genetics of adaptation — in Cape Verde and potentially beyond. If you’re interested in trait architecture, island evolution, or multiparent populations, I hope you’ll find it useful. academic.oup.com/genetics/adv...

Uncovering adaptation with a new Arabidopsis thaliana multiparent intercross population

By recombining the two island lineages, we can now study adaptive alleles in a shared background and uncover their effects without the confounding structure of the natural populations. This gives us a clearer picture of how these populations adapted after colonizing Cape Verde.

We detected major functional variants: 🌼 FLC R3X and FRI K232X — strongly affecting flowering time 🧲 IRT1 G130X — influencing photosynthesis and plant size ➕ Evidence for epistasis Several of these variants are fixed on one island, so they had been elusive in previous mapping efforts.

We focused on traits likely shaped by Cape Verde’s short growing season and nutrient-poor volcanic soils: ⏱️ Flowering time 🍃 Rosette size 🌿 Photosystem II efficiency (ΦPSII) These traits connect directly to survival in a tough environment.

So, we developed a new multiparent intercross population to overcome this issue, mix island-specific variants and break up long-range LD —letting us map adaptive variants that natural GWAS panels couldn’t detect and giving us a clearer window into adaptation.

Cape Verde is a fascinating system: two island populations, isolated for thousands of years, each adapting independently to a very harsh environment. Scientifically this is great — but the extreme population structure means GWAS can’t detect many adaptive variants.

Excited to share our new paper on Arabidopsis adaptation in the Cape Verde Islands!! 🌱🌋 We developed a new multiparent intercross population to uncover genetic variants that were previously difficult to map. Here’s a quick overview 👇🧵 @GeneticsGSA academic.oup.com/genetics/adv...
