Despite intensive research, little is known about the origin of the angiosperms and their rise
to ecological dominance during the Early Cretaceous. Based on whole-genome analyses of …

Highlights•Polyploidy or whole-genome duplication (WGD) is a ubiquitous feature of plant
genomes.•Polyploidy is most frequent in angiosperms.•A complex pattern of polyploidy is …

Large-scale (segmental or whole) genome duplication has been recurring in angiosperm
evolution. Subsequent gene loss and rearrangements further affect gene copy numbers and …

Polyploidy has long been recognized as a major force in angiosperm evolution. Recent
genomic investigations not only indicate that polyploidy is ubiquitous among angiosperms …

Flowering plants, or angiosperms, consist of more than 300,000 species, far more than any
other land plant lineages. The accumulated evidence indicates that multiple ancient …

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

Background Although it is agreed that a major polyploidy event, gamma, occurred within the
eudicots, the phylogenetic placement of the event remains unclear. Results To determine …

Polyploidy is a common mode of speciation and evolution in angiosperms (flowering plants).
In contrast, there is little evidence to date that whole genome duplication (WGD) has played …

Biodiversity results from multiple evolutionary mechanisms, including genetic variation and
natural selection. Whole-genome duplications (WGDs), or polyploidizations, provide …

Gene duplications provide evolutionary potentials for generating novel functions, while
polyploidization or whole genome duplication (WGD) doubles the chromosomes initially and …
