• Premise of the study: Hybridization and polyploidization (allopolyploidy) are ubiquitous in
the evolution of plants, but tracing the origins and subsequent evolution of the constituent …

Although plant polyploidization is ubiquitous in nature, polyploidy has long been considered
an evolutionary dead end, precluding further species diversification. However, recent …

allopolyploids.•Duplicate gene loss in allopolyploids is often distinctly non …

Polyploidy has contributed to the divergence and domestication of plants; however,
estimation of the relative roles that different types of polyploidy have played during evolution …

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 …

Allopolyploid speciation is widespread in plants, yet the molecular requirements for
successful orchestration of coordinated gene expression for two divergent and reunited …

Highlights• A single subgenome in allopolyploids may contribute to the majority of the

Polyploidization is a well‐known speciation and adaptation mechanism. Traces of former
polyploidization events were discovered within many genomes, and especially in plants …

Polyploidy, or whole genome multiplication, is ubiquitous among angiosperms. Many crop
species are relatively recent allopolyploids, resulting from interspecific hybridization and …
