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

Polyploidy, defined as the coexistence of three or more complete sets of chromosomes in an
organism's cells, is considered as a pivotal moving force in the evolutionary history of …

The importance of whole-genome duplication (WGD) for evolution is controversial. Whereas
some view WGD mainly as detrimental and an evolutionary dead end, there is growing …

It has long been recognized that hybridization and polyploidy are prominent processes in
plant evolution. Although classically recognized as significant in speciation and adaptation …

With advanced sequencing technology, dozens of complex polyploid plant genomes have
been characterized. However, for many polyploid species, their diploid ancestors are …

Whole-genome duplication (WGD), which leads to polyploidy, is implicated in adaptation
and speciation. But what are the immediate effects of WGD and how do newly polyploid …

The majority of the crops and vegetables of today were domesticated from their wild
progenitors within the past 12 000 years. Considerable research effort has been expended …

Biological invasions impose ecological and economic problems on a global scale, but also
provide extraordinary opportunities for studying contemporary evolution. It is critical to …

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

Angiosperms show a remarkable range in genome size (GS), yet most species have small
genomes, despite the frequency of polyploidy and repeat amplification in the ancestries of …
