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

Allopolyploidy is an important process during plant evolution that results in the reunion of
two divergent genomes into a common nucleus. Many of the immediate as well as longer …

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 …

We present an overview of the cotton genus (Gossypium) as a model for the study of
polyploidy. A synopsis of the origin and evolution of polyploid cotton is provided, offering an …

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 …

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 …

Recent work has demonstrated that allopolyploid speciation in plants may be associated
with non-Mendelian genomic changes in the early generations following polyploid …

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 …

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 …

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