Polyploidy is an important force in the evolution of flowering plants. Genomic merger and
doubling induce an extensive array of genomic effects, including immediate and long-term …

Background Polyploidy has played a prominent role in shaping the genomic architecture of
the angiosperms. Through allopolyploidization, several modern Gossypium (cotton) species …

Most eukaryotes have genomes that exhibit high levels of gene redundancy, much of which
seems to have arisen from one or more cycles of genome doubling. Polyploidy has been …

Allopolyploidy is an evolutionary and mechanistically intriguing process, in that it entails the
reconciliation of two or more sets of diverged genomes and regulatory interactions. In this …

Background Modern allotetraploid cotton contains an “A” and “D” genome from an ancestral
polyploidy event that occurred approximately 1–2 million years ago. Diploid A-and D …

Polyploidy is an important driver of eukaryotic evolution, evident in many animals, fungi, and
plants. One consequence of polyploidy is subfunctionalization, in which the ancestral …

Of the many processes that generate gene duplications, polyploidy is unique in that entire
genomes are duplicated. This process has been important in the evolution of many …

A putative advantage of allopolyploidy is the possibility of differential selection of duplicated
(homeologous) genes originating from two different progenitor genomes. In this note we …

Background Allopolyploid speciation requires rapid evolutionary reconciliation of two
diverged genomes and gene regulatory networks. Here we describe global patterns of gene …

Polyploid formation and processes that create partial genomic duplication generate
redundant genomic information, whose fate is of particular interest to evolutionary biologists …
