Cadmium intake in humans derives primarily from vegetable foods, yet the extent to which the chemical form and dose of cadmium in such foods influences the fate and toxicity of this metal is poorly understood. We have compared the fate in mice of trace levels--approximating that in agriculturally produced grain--and high levels of cadmium supplied as wheat(More)
The previously cloned DNA fragment which complements the behavioral defects of the che-1 and che-3 mutations of Rhizobium meliloti codes for two nearly identical (93%) flagellin genes. A wild-type copy of one of the two genes (flaA) but not the other (flaB) can complement the mutations. The behavior and flagellar morphology of newly isolated strains(More)
