… Here, we sampled and resequenced genomes of foothill (growing in elevations 460 to 980
m asl) as well as adjacent alpine (1,625 to 2,270 m asl) populations from all known foothill–…

Supergenes govern multi-trait-balanced polymorphisms in a wide range of systems;
however, our understanding of their origins and evolution remains incomplete. The reciprocal …

Why species have geographically restricted distributions is an unresolved question in ecology
and evolutionary biology. Here, we test a new explanation that mutation accumulation due …

Sequencing pooled DNA of multiple individuals from a population instead of sequencing
individuals separately has become popular due to its cost-effectiveness and simple wet-lab …

… Genomic data suggest divergence between these lineages is low and that some amount
of gene flow has occurred in the recent past (Fracassetti and Willi unpubl.). Crosses between …

Fertilization in angiosperms involves the germination of pollen on the stigma, followed by the
extrusion of a pollen tube that elongates through the style and delivers two sperm cells to …

A crucial step in the transition from outcrossing to self‐fertilization is the loss of genetic self‐incompatibility
( SI ). In the Brassicaceae, SI involves the interaction of female and male …

The Arctic is one of the most extreme terrestrial environments on the planet. Here, we present
the first chromosome‐scale genome assembly of a plant adapted to the high Arctic, Draba …

Demography determines the strength of genetic drift, which generally reduces genetic
variation and the efficacy of selection. Here, we disentangled the importance of demographic …

Polyploidy, or whole-genome duplication, is a common speciation mechanism in plants. An
important barrier to polyploid establishment is a lack of compatible mates. Because self-…
