Polyploidy, a state in which the chromosome complement has undergone an increase, is a
major force in evolution. Understanding the consequences of polyploidy has received much …

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

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 …

Here, we describe the evolution of gene expression among a diversified cohort of five
allopolyploid species in the cotton genus (Gossypium). Using this phylogenetic framework …

The merger of evolutionarily diverged genomes to form a new polyploid genetic system can
involve extensive remodeling of gene regulation. A recent paper in BMC Biology provides …

Polyploidization events such as whole-genome duplication and inter-species hybridization
are major evolutionary forces that shape genomes. Although long-term effects of …

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

Polyploidization has occurred often in the evolutionary history of eukaryotes, yet we are only
now learning about the genetic and epigenetic events that occur in newly formed polyploids …

Polyploidy can be classified as autopolyploidy (whole‐genome duplication within a species)
and allopolyploidy (duplication of genomes between species). While changes in …

Polyploidy is a major evolutionary process in eukaryotes—particularly in plants and, to a
less extent, in animals, wherein several past and recent whole-genome duplication events …
