About Gossypium raimondii

Gossypium raimondii is a species of cotton plant endemic to northern Peru. The Gossypium genus is ideal for investigating emergent consequences of polyploidy. A-genome diploids native to Africa and Mexican D-genome diploids diverged ∼5--10 Myr ago. They were reunited ∼1--2 Myr ago by trans-oceanic dispersal of a maternal A-genome propagule resembling G. herbaceum to the New World, hybridisation with a native D-genome species resembling G. raimondii, and chromosome doubling. The nascent AtDt allopolyploid spread throughout the American tropics and subtropics, diverging into at least five species; two of these species (G. hirsutum and G. barbadense) were independently domesticated to spawn one of the world's largest industries (textiles) and become a major oilseed.
