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 …

Understanding the composition, evolution, and function of the Gossypium hirsutum (cotton)
genome is complicated by the joint presence of two genomes in its nucleus (AT and DT …

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 …

Allotetraploid cotton (Gossypium) species represents a model system for the study of plant
polyploidy, molecular evolution, and domestication. Here, chromosome-scale genome …

Polyploid formation and processes that create partial genomic duplication generate
redundant genomic information, whose fate is of particular interest to evolutionary biologists …

Polyploidy plays a major role in genome evolution, which corresponds to environmental
changes over millions of years. The mechanisms of genome evolution, particularly during …

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

Allotetraploid cotton species are a vital source of spinnable fiber for textiles. The polyploid
nature of the cotton genome raises many evolutionary questions as to the relationships …

Background SNPs are the most abundant polymorphism type, and have been explored in
many crop genomic studies, including rice and maize. SNP discovery in allotetraploid cotton …

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 …
