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

Polyploidy, or the duplication of entire genomes, has been observed in prokaryotic and
eukaryotic organisms, and in somatic and germ cells. The consequences of polyploidization …

Ancient whole-genome duplications (WGDs or polyploidy) are prevalent in plants, and some
WGDs occurred during the timing of severe global environmental changes. It has been …

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 …

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 …

Whole-genome duplication (WGD) is characteristic of almost all fundamental lineages of
land plants. Unfortunately, the timings of WGD events are loosely constrained and …

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

The prevalence of autopolyploids in angiosperms has long been a subject of debate.
Müntzing (1936) and Darlington (1937) concluded that autopolyploids were common and …

Polyploidy, the condition of possessing more than two complete genomes in a cell, has
intrigued biologists for almost a century. Polyploidy is found in many plants and some animal …

Polyploidy has long been considered a major force in plant evolution. G. Ledyard Stebbins,
Jr., an architect of the Modern Synthesis, elegantly addressed a broad range of topics, from …
