Abstract:
... Fusarium wilt, caused by Fusarium oxysporum f. sp. vasinfectum, is a severe disease of cotton (Gossypium spp.). Strains of the wilt pathogen in the United States, such as race 1, require the presence of nematodes such as southern root-knot nematode (Meloidogyne incognita) to cause appreciable disease. The exception is the race 4 strain of the wilt pathogen, which can attack cotton without concomit ...

Abstract:
... Organic cotton (Gossypium hirsutum L.) production in the United States is steadily growing because of increased consumer demand, market premium prices, and regulatory shifts. As organic production expands in the United States, adventitious presence of genetically engineered (GE) traits caused by either pollen‐ or seed‐mediated gene flow from nonorganically grown sources of cotton raises concerns a ...

Abstract:
... Traditional breeding efforts dramatically transformed the cotton (Gossypium spp.) plant during the last century. In the coming decade, the high priority breeding objectives for production regions of the western US (far-western Texas, New Mexico, Arizona, and California) will involve morphologically complex traits controlled by many interacting genes. Although perennial concerns regarding yield, re ...
