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.
在大肠杆菌B与K-12杂交菌株中,I组吡哆醇突变在染色体上的位置显示与dsdA、aroC和purF(旧称purC)相邻。所有先前通过营养测试和转导频率测试归类为I组的突变体都显示与dsdA连锁。
