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

Comparative population genomics offers an excellent opportunity for unraveling the genetic
history of crop domestication. Upland cotton (Gossypium hirsutum) has long been an …

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

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 …

Phenotypic diversity and evolutionary innovation ultimately trace to variation in genomic
sequence and rewiring of regulatory networks. Here, we constructed a pan-genome of the …

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

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 …

Large-scale genomic surveys of crop germplasm are important for understanding the
genetic architecture of favorable traits. The genomic basis of geographic differentiation and …

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 …

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 …
