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 …

Allopolyploidization is accompanied by changes in gene expression that are thought to
contribute to phenotypic diversification. Here we describe global changes in the single …

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 …

Polyploidy complicates transcriptional regulation and increases phenotypic diversity in
organisms. The dynamics of genetic regulation of gene expression between coresident …

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 …

Cis and trans regulatory divergence underlies phenotypic and evolutionary diversification.
Relatively little is understood about the complexity of regulatory evolution accompanying …

Pima cotton (G ossypium barbadense) is widely cultivated because of its long, strong seed
trichomes ('fibers') used for premium textiles. These agronomically advanced fibers were …

Polyploidy is an evolutionary innovation for many animals and all flowering plants, but its
impact on selection and domestication remains elusive. Here we analyze genome evolution …

Gossypium hirsutum L.(Upland cotton) has an evolutionary history involving inter-genomic
hybridization, polyploidization, and subsequent domestication. We analyzed the …

Background Cotton has been cultivated and used to make fabrics for at least 7000 years.
Two allotetraploid species of great commercial importance, Gossypium hirsutum and …
