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

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 …

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 …

For nearly a century, biologists, and botanists in particular, have been interested in the
determination and documentation of chromosome numbers for extant taxa (reviewed in …

Deciphering the global distribution of polyploid plants is fundamental for understanding
plant evolution and ecology. Many factors have been hypothesized to affect the uneven …

Polyploidy is a major force in plant evolution and speciation. In newly formed allopolyploids,
pairing between related chromosomes from different subgenomes (homoeologous …

Domesticated food crops are derived from a phylogenetically diverse assemblage of wild
ancestors through artificial selection for different traits. Our understanding of domestication …

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

Hybridization has many and varied impacts on the process of speciation. Hybridization may
slow or reverse differentiation by allowing gene flow and recombination. It may accelerate …

Background Biological invasions are a major ecological and socio-economic problem in
many parts of the world. Despite an explosion of research in recent decades, much remains …
