Polyploidy and interspecific hybridization: partners for adaptation, speciation and evolution in plants
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, the nucleotype, and novelty: the impact of genome doubling on the biology of the cell
Polyploidy is a key mechanism of genome evolution and speciation, particularly in plants.

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

Nested radiations and the pulse of angiosperm diversification: increased diversification rates often follow whole genome duplications
Our growing understanding of the plant tree of life provides a novel opportunity to uncover
the major drivers of angiosperm diversity. Using a time‐calibrated phylogeny, we …

Allopolyploidy, diversification, and the Miocene grassland expansion
The role of polyploidy, particularly allopolyploidy, in plant diversification is a subject of
