Cotton's domestication story is written in its genes — and understanding which wild relatives carry untapped traits could help breeders develop varieties that need less water, fewer pesticides, or thrive in hotter climates.
Scientists looked at the DNA of many different cotton plants to figure out where cotton came from and how humans gradually changed it over thousands of years of farming. By comparing wild and domesticated types, they can see which genes were selected during that process. This kind of map helps plant breeders find useful traits that were lost during domestication and potentially bring them back.
Key Findings
The study examined genomic diversity across cotton species to reconstruct the domestication timeline
Domestication narrowed the genetic diversity of cultivated cotton compared to wild relatives
Wild cotton relatives retain genetic variation that could be valuable for improving modern crop varieties

Cotton is a soft, fluffy staple fiber that grows in a boll, or protective case, around the seeds of the cotton plants of the genus Gossypium in the mallow family Malvaceae. The fiber is almost pure cellulose and may contain minor percentages of waxes, fats, pectins, and water. Under natural condi...
