Almost all extant plant species have doubled their genomes at least once in their
evolutionary histories, resulting in polyploidy which provided a rich genomic resource for …

Polyploidy is a common mode of speciation that can have far‐reaching consequences for
plant ecology and evolution. Because polyploidy can induce an array of phenotypic …

In 1950, G. Ledyard Stebbins devoted two chapters of his book Variation and Evolution in
Plants (Columbia Univ. Press, New York) to polyploidy, one on occurrence and nature and …

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 …

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

Highlights•Many recent and ancient allopolyploids exhibit subgenome
dominance.•Extensive homoeologous exchanges complicate accurate subgenome …

Polyploidy is an important force shaping plant genomes. All flowering plants are
descendants of an ancestral polyploid species, and up to 70% of extant vascular plant …

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 …

The occurrence of polyploidy in land plant evolution has led to an acceleration of genome
modifications relative to other crown eukaryotes and is correlated with key innovations in …

Allopolyploidization (hybridization and whole-genome duplication) is a common
phenomenon in plant evolution with immediate saltational effects on genome structure and …
