Characterization of pyridoxine auxotrophs of Escherichia coli: chromosomal position of linkage group I |
|
| Authors: | W B Dempsey |
| Abstract: | The chromosomal location of Group I pyridoxine mutations in Escherichia coli is shown to be adjacent to dsdA,aroC, and purF (old purC) in E. coli B x K-12 hybrids. All mutants previously classified into Group I by nutrition tests and transduction frequency tests are shown to be linked to dsdA. |
