Mutations in the genes pgi, pfkA, and ptsG resulted in a maltose Blu phenotype in Escherichia coli K-12, bringing the number of known Blu alleles to six. The Blu phenotype, as visualized by staining with iodine vapor, is a convenient mutant isolation technique.
基因pgi、pfkA和ptsG中的突变导致大肠杆菌K-12出现麦芽糖Blu表型,使已知的Blu等位基因数量增加到6个。通过碘蒸气染色观察到的Blu表型是一种便捷的突变体分离技术。
