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 …

Cotton (Gossypium spp.) is one of the most important economic crops in the world and also
a major source of natural fiber, oil, and protein. The morphology of cotton species varies …

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

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 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 …

Background Tetraploid cotton contains two sets of homologous chromosomes, the At-and Dt-
subgenomes. Consequently, many markers in cotton were mapped to multiple positions …

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

Genome duplication is thought to be central to the evolution of morphological complexity,
and some polyploids enjoy a variety of capabilities that transgress those of their diploid …

Both ancient and recent polyploidy, together with post-polyploidization loss of many
duplicated gene copies, complicates angiosperm comparative genomics. To explore an …

We present an overview of Gossypium genome evolution and the implications of this
understanding for targeted breeding objectives. The cotton genus (Gossypium) contains …
