Abstract Genetic studies leveraging natural variation in Arabidopsis species have improved our understanding of evolutionary genetic processes underlying ecologically important and adaptive traits. Integrating the thorough functional knowledge accumulated in A. thaliana with the extensive natural variation in outcrossing Arabidopsis species is …

Abstract Flow cytometry provides a reliable and fast method for estimating genome size and ploidy levels in plants. Until recently, most studies employed fresh tissues, which limits the use of the method with samples from remote areas or when an extremely high …

Abstract Regional seed sources are increasingly used in ecological restoration. Polyploid complexes, i.e. taxa comprising multiple ploidy levels, are often part of regional seed mixtures, where ploidy levels are often not distinguished. However, mixing ploidy levels may foster their hybridisation, severely reduce …

Whole-genome duplication (WGD), a widespread macromutation across eukaryotes, is predicted to affect the tempo and modes of evolutionary processes. By theory, the additional set(s) of chromosomes present in polyploid organisms may reduce the efficiency of selection while, simultaneously, increasing heterozygosity and buffering …

Background: Wild relatives in the genus Arabidopsis are recognized as useful model systems to study traits and evolutionary processes in outcrossing species, which are often difficult or even impossible to investigate in the selfing and annual Arabidopsis thaliana. However, Arabidopsis as a …
