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

Most land plants are now known to be ancient polyploids that have rediploidized.
Diploidization involves many changes in genome organization that ultimately restore …

Common oat (Avena sativa) is an important cereal crop serving as a valuable source of
forage and human food. Although reference genomes of many important crops have been …

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

Background Despite the prevalence and recurrence of polyploidization in the speciation of
flowering plants, its impacts on crop intraspecific genome diversification are largely …

The fruits of diploid and octoploid strawberry (Fragaria spp) show substantial natural
variation in color due to distinct anthocyanin accumulation and distribution patterns …

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

Most diploid organisms have polyploid ancestors. The evolutionary process of
polyploidization is poorly understood but has frequently been conjectured to involve some …

Cultivated strawberry (Fragaria× ananassa) is one of our youngest domesticates, originating
in early eighteenth-century Europe from spontaneous hybrids between wild allo-octoploid …

Teleost fishes, which are the largest and most diverse group of living vertebrates, have a rich
history of ancient and recent polyploidy. Previous studies of allotetraploid common carp and …
