Polyploidy has played a pivotal and recurring role in angiosperm evolution. Allotetraploids
arise from hybridization between species and possess duplicated gene copies (homeologs) …

Highlights•Genomic legacies of the ancestors may affect duplicate gene evolution in
allopolyploids.•Duplicate gene loss in allopolyploids is often distinctly non …

Polyploidy has occurred throughout the evolutionary history of all eukaryotes and is
extremely common in plants. Reunification of the evolutionarily divergent genomes in …

Polyploidy is an important evolutionary process throughout eukaryotes, particularly in
flowering plants. Duplicated gene pairs (homoeologs) in allopolyploids provide additional …

Background Allopolyploid speciation requires rapid evolutionary reconciliation of two
diverged genomes and gene regulatory networks. Here we describe global patterns of gene …

• 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 …

Polyploidization can have a significant ecological and evolutionary impact by providing
substantially more genetic material that may result in novel phenotypes upon which …

Highlights•Many recent and ancient allopolyploids exhibit subgenome
dominance.•Extensive homoeologous exchanges complicate accurate subgenome …

Whole-genome duplications (WGDs) are a prominent process of diversification in
eukaryotes. The genetic and evolutionary forces that WGD imposes on cytoplasmic …

Allopolyploidization (hybridization and whole-genome duplication) is a common
phenomenon in plant evolution with immediate saltational effects on genome structure and …
