Autopolyploidization presents a transient and potential-rich window of increased transcriptional plasticity in Arabidopsis arenosa. https://www.biorxiv.org/content/10.64898/2026.06.16.732565v1

@soniacelestini.bsky.social @lipanovaveronika.bsky.social J. Vlček & F. Kolář combined soil data with genomes of 76 populations of diploid–autotetraploid Arabidopsis arenosa to test adaptation to distinct soil types between ploidies. 🔗 doi.org/10.1093/molbev/msaf298 #evobio #molbio

Whole-Genome Duplication Reshapes Adaptation: Autotetraploid Arabidopsis arenosa Leverages its High Genetic Variation to Compensate for Selection Constraints

Abstract. Whole-genome duplication (WGD), a widespread macromutation across eukaryotes, is predicted to affect the tempo and modes of evolutionary processe

Coexisting With Humans: Genomic and Behavioral Consequences in a Small and Isolated Bear Population

Abstract. Climate and land use change have increased human–wildlife interactions, potentially reducing wild species density and prompting behavioral adapta

Colossal Bioscience did not revive dire wolves, despite a sensationalist Time Magazine cover story. Making genetically modified animals that are cosplaying as extinct species is not de-extinction.

Dire wolves were not close relatives of gray wolves. They last shared a common ancestor more than 5 million years ago. What Colossal has done is make something new and slapped a dire wolf sticker on it, as if an organism equals a hypothetical genome.

My preprint is finally out on bioRxiv! 🌿🧬 It’s the result of years of work and thinking about how whole-genome duplication shapes evolution. If you're into polyploidy and adaptation, have a look! ✨ #Polyploidy #EvolutionaryGenomics

Leaf cuticule traits evolved in alpine populations of Arabidopsis arenosa 🌱. Nice way to say hi to Bluesky 🦋 doi.org/10.1111/nph....

Repeated colonisation of alpine habitats by Arabidopsis arenosa involved parallel adjustments of leaf cuticle traits

Cuticle function can be pivotal to plant success in different environments. Yet, the occurrence of intraspecific adjustments in cuticle traits resulting from acclimation or adaptation to different h...
