Asymmetric subgenome selection and cis -regulatory divergence during cotton domestication

Xianlong Zhang, Keith Lindsey and colleagues report a population genomic analysis of Upland cotton (Gossypium hirsutum) that identifies 93 potential domestication-sweep regions and 19 candidate loci for fiber-quality-related traits. Their analysis provides evidence for asymmetric subgenome selection for long white fibers in cultivated cotton.
