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

▪ Abstract Polyploidy is widely acknowledged as a major mechanism of adaptation and
speciation in plants. The stages in polyploid evolution include frequent fertility bottlenecks …

Advances in recent years have revolutionized our understanding of both the context and
occurrence of polyploidy in plants. Molecular phylogenetics has vastly improved our …

Genome doubling, or polyploidy, is a major factor accounting for duplicate genes found in
most eukaryotic genomes. Polyploidy has considerable effects on duplicate gene …

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 …

Highlights•Post-polyploid diploidization (PPD) in angiosperms usually operates by
descending dysploidy.•PPD is acting with differing intensities and rates.•Multiple base …

Polyploidy or whole genome duplication (WGD) occurs throughout the evolutionary history
of many plants and some animals, including crops such as wheat, cotton, and sugarcane …

An essay on how modern flowering plant genomes are derived from processes of repeated,
episodic whole-genome doubling, or polyploidy, is presented. Topics discussed include …

The importance of hybridization in plant speciation and evolution has been debated for
decades, with opposing views of hybridization as either a creative evolutionary force or …

Polyploidy has long been considered a major force in plant evolution. G. Ledyard Stebbins,
Jr., an architect of the Modern Synthesis, elegantly addressed a broad range of topics, from …
