Background Polyploidy or whole-genome duplication is now recognized as being present in
almost all lineages of higher plants, with multiple rounds of polyploidy occurring in most …

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

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 …

Genome sequence data are now being routinely obtained from many nonmodel organisms.
These data contain a wealth of information about the demographic history of the populations …

We consider the rapidly advancing discipline of plant evolutionary genomics, with a focus on
the evolution of polyploid genomes. In many lineages, polyploidy is followed by 'biased …

Teff (Eragrostis tef) is a cornerstone of food security in the Horn of Africa, where it is prized
for stress resilience, grain nutrition, and market value. Here, we report a chromosome-scale …

During evolution successful allopolyploids must overcome 'genome shock'between
hybridizing species but the underlying process remains elusive. Here, we report concerted …

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

Gene duplication is an important mechanism for adding to genomic novelty. Hence, which
genes undergo duplication and are preserved following duplication is an important question …

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