We report a genetic analysis of a recessive chromosomal mutation of Escherichia coli K-12 that is responsibel for masking the sexual expression of an F factor that it carries. We call this new bacterial gene, which is closely linked to thr, fex, for F expression.
我们报道了对大肠杆菌K-12一种隐性染色体突变的遗传分析,该突变负责掩盖其所携带的F因子的性表达。我们将这个与苏氨酸、fex紧密连锁的新细菌基因称为fex,用于F表达。
