Autopolyploidy exacerbates dominance masking under negative frequency-dependent selection: evidence from sporophytic self-incompatibility in Arabidopsis arenosa and A. lyrata

The paper shows autopolyploidy reduces heterozygosity at self-incompatibility loci under dominance masking, using Arabidopsis species data.

A Global Genomic Resource for Outcrossing Arabidopsis lyrata and Arabidopsis arenosa

The paper presents a genomic resource with 1018 A. lyrata and 736 A. arenosa genomes, enabling studies of adaptation and genetic diversity through a searchable database and GWAS analysis of latitudinal clines.

Whole-genome duplication reshapes adaptation: autotetraploid Arabidopsis arenosa leverages its high genetic variation to compensate for selection constraints.

This study compares genomic adaptation in diploid and autotetraploid Arabidopsis arenosa populations, finding that tetraploids retain more genetic variation and use it to compensate for selection constraints.

Whole-genome duplication increases genetic diversity and load in outcrossing Arabidopsis

This study examines how whole-genome duplication affects genetic diversity and mutation load in Arabidopsis arenosa, showing increased diversity but modest load increases.
