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

Plant genomes vary in size and complexity, fueled in part by processes of whole-genome
duplication (WGD; polyploidy) and subsequent genome evolution. Despite repeated …

Polyploidy, or whole genome multiplication, is ubiquitous among angiosperms. Many crop
species are relatively recent allopolyploids, resulting from interspecific hybridization and …

Nascent allohexaploid wheat may represent the initial genetic state of common wheat
(Triticum aestivum), which arose as a hybrid between Triticum turgidum (AABB) and …

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 …

Perilla is a young allotetraploid Lamiaceae species widely used in East Asia as herb and oil
plant. Here, we report the high-quality, chromosome-scale genomes of the tetraploid (Perilla …

Polyploidy (whole‐genome duplication, WGD) is an integral feature of eukaryotic evolution
with two main forms typically recognized, autopolyploidy and allopolyploidy. In plants, a …

In recent years, wheat yield per hectare appears to have reached a plateau, leading to
concerns for future food security with an increasing world population. Since its invention …

Polyploids, which arise from whole-genome duplication events, have contributed to genome
evolution throughout eukaryotes. Among plants, novel features of neopolyploids include …
