The Nature of Centromeric Repeat Turnovers in the genus Arabidopsis

This study identifies centromeric repeat turnovers in Arabidopsis species, revealing evolutionary mechanisms and the role of genetic drift and centromere drive in repeat replacement.

Copy Number Variation: A Substrate for Plant Adaptation and Stress Response in Arabidopsis

The paper identifies rapidly evolving gene families and environmentally associated CNVs in Arabidopsis species, showing their role in adaptation and stress response.

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.

Diploid origins and early genome stabilization in the allotetraploid Arabidopsis suecica

This study investigates the origin and early genome evolution of Arabidopsis suecica, identifying de novo adaptation and functional compensation between homeologous genes.

Life-history trade-offs explain local adaptation in Arabidopsis thaliana

This study shows that local adaptation in Arabidopsis thaliana involves strong and variable selection on multiple traits, with trade-offs and life-history strategies affecting fitness.

Multiple polyploidizations in Arabidopsis lyrata stabilized by long-range adaptive introgression across Eurasia

The paper identifies multiple origins of autotetraploidy in Arabidopsis lyrata across Eurasia and shows how adaptive introgression stabilizes these polyploid forms.

Inference of polyploid origin and inheritance mode from population genomic data

This paper presents two bioinformatics methods to infer polyploid origin and inheritance modes from short-read sequencing data by analyzing allelic read depth and phased haplotypes.

Unstable inheritance of 45S rRNA genes in Arabidopsis thaliana

The paper shows that rRNA gene copy number variation in Arabidopsis thaliana is heritable but unstably inherited, explaining why GWAS failed to identify the NORs as the source.
