Genome-wide gene relationships among five allotetraploid cottons, along with noted key fiber development genes. The results indicate remarkably high overall sequence similarity yet drastically different fiber morphology between domesticated (Gossypium hirsutum, G. barbadense) and wild (G. mustelinum, G. tomentosum, G. darwinii) species.
