Evolutionary footprints of a cold relic in a rapidly warming world (2021)
Journal Article

With accelerating global warming, understanding the evolutionary dynamics of plant adaptation to environmental change is increasingly urgent. Here we reveal the enigmatic history of the genus Cochlearia (Brassicaceae), a Pleistocene relic that origin... Read More about Evolutionary footprints of a cold relic in a rapidly warming world.

Transposable element annotation in non‐model species: The benefits of species‐specific repeat libraries using semi‐automated EDTA and DeepTE de novo pipelines (2021)
Journal Article

Transposable elements (TEs) are significant genomic components which can be detected either through sequence homology against existing databases or de novo, with the latter potentially reducing the risk of underestimating TE abundance. Here, we descr... Read More about Transposable element annotation in non‐model species: The benefits of species‐specific repeat libraries using semi‐automated EDTA and DeepTE de novo pipelines.

Parallel adaptation in autopolyploid Arabidopsis arenosa is dominated by repeated recruitment of shared alleles (2021)
Journal Article

Relative contributions of pre-existing vs de novo genomic variation to adaptation are poorly understood, especially in polyploid organisms. We assess this in high resolution using autotetraploid Arabidopsis arenosa, which repeatedly adapted to toxic...

Polyploidy underlies co-option and diversification of biosynthetic triterpene pathways in the apple tribe (2021)
Journal Article

Whole-genome duplication (WGD) plays important roles in plant evolution and function, yet little is known about how WGD underlies metabolic diversification of natural products that bear significant medicinal properties, especially in nonmodel trees.... Read More about Polyploidy underlies co-option and diversification of biosynthetic triterpene pathways in the apple tribe.

Novelty and Convergence in Adaptation to Whole Genome Duplication (2021)
Journal Article

Whole genome duplication (WGD) can promote adaptation but is disruptive to conserved processes, especially meiosis. Studies in Arabidopsis arenosa revealed a coordinated evolutionary response to WGD involving interacting proteins controlling meiotic...

Population genomic and historical analysis suggests a global invasion by bridgehead processes in Mimulus guttatus (2021)
Journal Article

© 2021, The Author(s). Imperfect historical records and complex demographic histories present challenges for reconstructing the history of biological invasions. Here, we combine historical records, extensive worldwide and genome-wide sampling, and de...

Adaptive introgression: how polyploidy reshapes gene flow landscapes (2021)
Journal Article

© 2021 The Authors. New Phytologist © 2021 New Phytologist Foundation Rare yet accumulating evidence in both plants and animals shows that whole genome duplication (WGD, leading to polyploidy) can break down reproductive barriers, facilitating gene f...

De Novo Mutation and Rapid Protein (Co-)evolution during Meiotic Adaptation in Arabidopsis arenosa (2021)
Journal Article

A sudden shift in environment or cellular context necessitates rapid adaptation. A dramatic example is genome duplication, which leads to polyploidy. In such situations, the waiting time for new mutations might be prohibitive; theoretical and empiric...

Maintenance of Adaptive Dynamics and No Detectable Load in a Range-Edge Outcrossing Plant Population (2021)
Journal Article

During range expansion, edge populations are expected to face increased genetic drift, which in turn can alter and potentially compromise adaptive dynamics, preventing the removal of deleterious mutations and slowing down adaptation. Here, we contras... Read More about Maintenance of Adaptive Dynamics and No Detectable Load in a Range-Edge Outcrossing Plant Population.
