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 …

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 …

For several years allopolyploid cottons have been the subject of evolutionary investigations
into the genomic mysteries of polyploidy. An array of genomic interactions have been …

Allotetraploid plant species originate when the genomes of diploid species are brought
together in hybrids and then duplicated, a process apparently initiated by fertilization …

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 …

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 …

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 …

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 …

Gossypium (cotton) has been developed as a particularly useful system for examining how
gene expression patterns and levels change after polyploidy. Recent studies have provided …

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 …
