The genetic architecture of repeated local adaptation to climate in distantly related plants
Closely related species often use the same genes to adapt to similar environments.
However, we know little about why such genes possess increased adaptive potential and …

The plant model system Arabidopsis set in an evolutionary, systematic, and spatio-temporal context
MA Koch - Journal of Experimental Botany, 2019 - academic.oup.com
Arabidopsis thaliana is one of the prevailing plant model systems used for most facets of
plant molecular, cell, and evolutionary biology. There are good reasons for that, such as …

Parallel adaptation in autopolyploid Arabidopsis arenosa is dominated by repeated recruitment of shared alleles
Relative contributions of pre-existing vs de novo genomic variation to adaptation are poorly
understood, especially in polyploid organisms. We assess this in high resolution using …

Genomic Patterns of Local Adaptation under Gene Flow in Arabidopsis lyrata
T Hämälä, O Savolainen - Molecular Biology and Evolution, 2019 - academic.oup.com
Short-scale local adaptation is a complex process involving selection, migration, and drift.
The expected effects on the genome are well grounded in theory but examining these on an …

Transposable elements maintain genome-wide heterozygosity in inbred populations
Elevated levels of inbreeding increase the risk of inbreeding depression and extinction, yet
many inbred species are widespread, suggesting that inbreeding has little impact on …

Local adaptation and ecological differentiation under selection, migration, and drift in Arabidopsis lyrata
How the balance between selection, migration, and drift influences the evolution of local
adaptation has been under intense theoretical scrutiny. Yet, empirical studies that relate …

Polyploids broadly generate novel haplotypes from trans-specific variation in Arabidopsis arenosa and Arabidopsis lyrata
M Bohutínská, E Petříková, TR Booker… - PLoS …, 2024 - journals.plos.org
Polyploidy, the result of whole genome duplication (WGD), is widespread across the tree of
life and is often associated with speciation and adaptability. It is thought that adaptation in …

Environmental response in gene expression and DNA methylation reveals factors influencing the adaptive potential of Arabidopsis lyrata
Understanding what factors influence plastic and genetic variation is valuable for predicting
how organisms respond to changes in the selective environment. Here, using gene …

Maintenance of adaptive dynamics and no detectable load in a range-edge outcrossing plant population
During range expansion, edge populations are expected to face increased genetic drift,
which in turn can alter and potentially compromise adaptive dynamics, preventing the …

Biased Gene Conversion Constrains Adaptation in Arabidopsis thaliana
Reduction of fitness due to deleterious mutations imposes a limit to adaptive evolution. By
characterizing features that influence this genetic load we may better understand constraints …
