Allopolyploids result from hybridization between different evolutionary lineages coupled with
genome doubling. Homoeologous chromosomes (chromosomes with common shared …

Polyploidy is a major force in plant evolution and speciation. In newly formed allopolyploids,
pairing between related chromosomes from different subgenomes (homoeologous …

Polyploidy is now recognized as a characteristic feature of all angiosperm genomes (Jiao et
al., 2011), and remains an important speciation process today (Wendel, 2000; Comai, 2005; …

Allopolyploidy is a prevalent process in plants, having important physiological, ecological
and evolutionary consequences. Transcriptomic responses to genomic merger and doubling …

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

Transposable elements (TEs) represent an important fraction of plant genomes and are
likely to play a pivotal role in fuelling genome reorganization and functional changes …

Autopolyploidy is more common in plants than traditionally assumed, but has received little
attention compared with allopolyploidy. Hence, the advantages and disadvantages of …

Polyploidy is an important force shaping plant genomes. All flowering plants are
descendants of an ancestral polyploid species, and up to 70% of extant vascular plant …

Enormous strides have been made in the study of polyploidy over the last 20 yr. Here, we
highlight some of these discoveries and note where our understanding of polyploid …

Polyploidization is an important mechanism for introducing diversity into a population and
promoting evolutionary change. It is believed that most, if not all, angiosperms have …
