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

Hybridization is an evolutionary phenomenon that has fascinated biologists for centuries.
Prior to the advent of whole-genome sequencing, it was clear that hybridization had played …

Cultivated strawberry emerged from the hybridization of two wild octoploid species, both
descendants from the merger of four diploid progenitor species into a single nucleus more …

High oil and protein content make tetraploid peanut a leading oil and food legume. Here we
report a high-quality peanut genome sequence, comprising 2.54 Gb with 20 …

Ancient polyploidization events have had a lasting impact on vertebrate genome structure,
organization and function. Some key questions regarding the number of ancient …

Polyploidy (genome duplication) is a pivotal force in evolution. However, the interactions
between parental genomes in a polyploid nucleus, frequently involving subgenome …

Polyploidy is a key mechanism of genome evolution and speciation, particularly in plants.
Many aspects of polyploidy have been elucidated with the tools that have become available …

All natural plant species are evolved from ancient polyploids. Polyloidization plays an
important role in plant genome evolution, species divergence and crop domestication. We …

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

All extant core-eudicot plants share a common ancestral genome that has experienced
cyclic polyploidizations and (re) diploidizations. Reshuffling of the ancestral core-eudicot …
