Highlights•Polyploidy is a common evolutionary feature in all eukaryotes especially in
plants.•Ploidy and intergenomic hybridization induce genetic and epigenetic changes.•DNA …

Plant genomes vary in size and complexity, fueled in part by processes of whole-genome
duplication (WGD; polyploidy) and subsequent genome evolution. Despite repeated …

The finding that even the smallest of plant genomes has incurred multiple genome-wide
chromatin duplication events, some of which may predate the origins of the angiosperms …

To study the evolutionary effects of polyploidy on plant gene functions, we analyzed
functional genomics data for a large number of duplicated gene pairs formed by ancient …

Polyploidy has been hypothesized to be both an evolutionary dead-end and a source for
evolutionary innovation and species diversification. Although polyploid organisms …

The occurrence of polyploidy in land plant evolution has led to an acceleration of genome
modifications relative to other crown eukaryotes and is correlated with key innovations in …

Volumes of flow sorted nuclei were analyzed from two highly endopolyploid (diploids with
endopolyploid tissues) species (Arabidopsis thaliana and Barbarea stricta), from a less …

Polyploidy or whole genome duplication (WGD) provides raw genetic materials for
sequence and expression evolution of duplicate genes. However, the mode and tempo of …

Structural variation is a major source of genetic diversity and an important substrate for
selection. In allopolyploids, homoeologous exchanges (ie between the constituent …

Polyploidy has long been recognized as a prominent force shaping the evolution of
eukaryotes, especially flowering plants. New phenotypes often arise with polyploid formation …
