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 …

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 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 …

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

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

The two cultivated allopolyploid cottons, Gossypium hirsutum and Gossypium barbadense,
represent a remarkable example of parallel independent domestication, both involving …

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 …

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 …

Allopolyploidization, resulting in divergent genomes in the same cell, is believed to trigger a
“genome shock”, leading to broad genetic and epigenetic changes. However, little is …

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