Varying importance of postzygotic isolation in polyploid speciation? A survey of the triploid block strength, its causal mechanisms, and evolutionary consequences

This study surveys variation in triploid block strength across angiosperms and finds no significant impact of assessed factors on triploid seed viability, suggesting mixed roles in interspecies gene flow.

Different resource partitioning explains plant species richness patterns in tropical alpine ecosystems

The paper compares resource partitioning strategies in two tropical alpine ecosystems to explain differences in species richness.

Impact of whole-genome duplications on structural variant evolution in the plant genus Cochlearia

This study examines how whole-genome duplications in Cochlearia plants increase structural variant diversity and its impact on adaptation to environmental changes.

Kinetochore and ionomic adaptation to whole genome duplication

This study identifies genetic adaptations to whole genome duplication in Cochlearia species, highlighting kinetochore and ion transport gene changes across multiple WGD events.

Novel reassortments of variation underlie repeated adaptation to whole genome duplication in two outcrossing Arabidopsis species

The paper identifies repeated selection signals in genes related to adaptation to whole genome duplication in two Arabidopsis species, showing that tetraploid-specific haplotype blocks arise from diverse allelic sources.

Inbreeding depression in polyploid species: a meta-analysis

This study investigates how polyploidy affects inbreeding depression in angiosperms, finding that its impact varies with the time since polyploidization.

Genomic basis and phenotypic manifestation of (non-)parallel serpentine adaptation in Arabidopsis arenosa

This study investigates parallel adaptation in Arabidopsis arenosa on serpentine soils, finding phenotypic parallelism but limited genomic parallelism, suggesting genetic redundancy in adaptation.

Niche differentiation following whole-genome duplication? The importance of considering the intricate evolutionary history of polyploids when assessing climatic niche evolution

This study investigates how niche differentiation in autopolyploids of Arabidopsis arenosa is influenced by evolutionary history, finding that niche shifts are driven by post-WGD processes rather than genome duplication alone.

Genomic signatures of sexual selection on pollen-expressed genes in Arabis alpina

The paper analyzes genomic signatures of sexual selection on pollen-expressed genes in Arabis alpina, finding stronger purifying selection in outbred populations.

Homozygosity at its Limit: Inbreeding Depression in Wild Arabidopsis arenosa Populations

The paper investigates inbreeding depression in wild Arabidopsis arenosa populations by analyzing hybrid plants and finds that increased homozygosity, rather than outbreeding depression, is associated with deleterious phenotypes.

Parallel adaptation in autopolyploid Arabidopsis arenosa is dominated by repeated recruitment of shared alleles

The paper investigates adaptation in autopolyploid Arabidopsis arenosa, finding that parallel adaptation is driven by shared alleles and rare de novo mutations in ion homeostasis genes.

Genomic basis of parallel adaptation varies with divergence in Arabidopsis and its relatives

The paper investigates genomic parallelism in Arabidopsis species adapting to alpine environments, finding that parallel adaptation decreases with increasing genetic divergence between lineages.

Parallel alpine differentiation in Arabidopsis arenosa

This study investigates parallel evolution in Arabidopsis arenosa by testing genetic and phenotypic parallelism across alpine and foothill populations.

Genomic novelty versus convergence in the basis of adaptation to whole genome duplication

This paper compares genomic adaptation to whole genome duplication in two species, finding gene-level divergence but process-level convergence in meiosis and stress responses.

Pervasive population genomic consequences of genome duplication in Arabidopsis arenosa

This study investigates the population genomic effects of polyploidy in Arabidopsis arenosa, finding subtle yet widespread impacts on evolutionary processes.
