Malvaceae comprise some 4,225 species in 243 genera and nine subfamilies and include
economically important species, such as cacao, cotton, durian, and jute, with cotton an …

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

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 …

The importance of whole-genome multiplication (WGM) in plant evolution has long been
recognized. In flowering plants, WGM is both ubiquitous and in many lineages cyclical, each …

Domestication in the cotton genus is remarkable in that it has occurred independently four
different times at two different ploidy levels. Relatively little is known about genome evolution …

Multiple cotton genomes (diploid and tetraploid) have been assembled. However, genomic
variations between cultivars of allotetraploid upland cotton (Gossypium hirsutum L.), the …

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 …

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 …

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