Second, in a genome scan we show that although most polymorphism is shared across ploidies, there is strong ploidy-associated allelic differentiation in 44 genes with discrete, mostly single-gene peaks of sharply elevated differentiation. Among these are eight meiosis genes encoding proteins that ...
Pervasive population genomic consequences of genome duplication in Arabidopsis arenosaEvolutionary geneticsPlant evolutionPopulation geneticsPloidy-variable species allow direct inference of the effects of chromosome copy number on fundamental evolutionary processes. While an abundance of theoretical work suggests ...

arenosa showed that the genome-wide proportion of non-synonymous polymorphisms fixed by directional selection was higher in tetraploids than in diploids, suggesting increased adaptive variation in natural autopolyploids8. However, it remains unclear whether such variation reflects increased input of novel...
Arabidopsis arenosa (L.) Lawalrée — sand rock cress A. arenosa subsp. arenosa (Europe: native in Austria, Belarus, Bosnia Herzegovina,Bulgaria, Croatia, Czech Republic, NE France,Germany,Hungary, N Italy,Latvia, Lithuania, Macedonia,Poland,Romania, Slovakia, Slovenia,Switzerland, and Ukraine;...
Here, we use transcriptome sequencing, genome resequencing scans for selection, and stress tolerance assays to study a weedy population of the otherwise nonweedy Arabidopsis arenosa, an obligately outbreeding relative of Arabidopsis thaliana Although weedy A. arenosa is widespread, a single genetic ...
genome size estimated by flow cytometry andk-mer analysis, respectively; see Extended Data Fig.1and Methods). Contigs were placed into scaffolds using chromatin conformation capture (Hi-C) data and using the reference genomes ofA. thalianaandArabidopsis lyrata(as substitute forA. arenosa) as ...
Arabidopsis is widely used as a model species for a series of obvious reasons: small physical size, short generation time, straightforward genetics, large number of offspring, and small genome size (Goodman et al., 1995). In addition, its full genomic sequence has been fully determined, and ...
Genome scans based on outlier analyses have revolutionized detection of genes involved in adaptive processes, but reports of some forms of selection, such as balancing selection, are still limited. It is unclear whether high throughput genotyping approaches for identification of single nucleotide polymorph...
