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 in populations of well-differentiated plant species is now widely recognized (1, 2).
Most reports, however, are limited to a few individuals from one or several populations and …

Hybridization and polyploidy have been considered as significant evolutionary forces in
adaptation and speciation, especially among plants. Interspecific gene flow generates novel …

In this chapter some of the salient features of polyploidy in plants, including a brief
description of its prevalence and modes of formation are discussed. Several model systems …

Polyploid organisms carry more than two copies of each chromosome, a condition rarely
tolerated in animals but which occurs relatively frequently in the plant kingdom. One of the …

The finding that even the smallest of plant genomes has incurred multiple genome-wide
chromatin duplication events, some of which may predate the origins of the angiosperms …

Allopolyploidy is a prominent mode of speciation in higher plants. Due to the coexistence of
closely related genomes, a successful allopolyploid must have the ability to invoke and …

Highlights•Polyploidy is a common evolutionary feature in all eukaryotes especially in
plants.•Ploidy and intergenomic hybridization induce genetic and epigenetic changes.•DNA …

Polyploidy, or whole genome multiplication, is ubiquitous among angiosperms. Many crop
species are relatively recent allopolyploids, resulting from interspecific hybridization and …

Polyploidy is a mutation with profound phenotypic consequences and thus hypothesized to
have transformative effects in plant ecology. This is most often considered in the context of …
