In the past decade, advances in genome sequencing have allowed researchers to uncover
the history of hybridization in diverse groups of species, including our own. Although the …

Main conclusion This article provides an up-to-date review concerning from basic issues of
polyploidy to aspects regarding the relevance and role of both natural and artificial …

Like many other crops, the cultivated peanut (Arachis hypogaea L.) is of hybrid origin and
has a polyploid genome that contains essentially complete sets of chromosomes from two …

Polyploidy is a key mechanism of genome evolution and speciation, particularly in plants.
Many aspects of polyploidy have been elucidated with the tools that have become available …

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

The importance of hybridization in plant speciation and evolution has been debated for
decades, with opposing views of hybridization as either a creative evolutionary force or …

Many organisms are currently polyploid, or have a polyploid ancestry and now have
secondarily'diploidized'genomes. This finding is surprising because retained whole-genome …

Speciation, that is, the evolution of reproductive barriers eventually leading to complete
isolation, is a crucial process generating biodiversity. Recent work has contributed much to …

Botanists have long believed that hybrid speciation is important, especially after
chromosomal doubling (allopolyploidy). Until recently, hybridization was not thought to play …

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