Abstract

A genetic marker responsible for the killing activity of PBSX, a defective phage carried by Bacillus subtilis 168, has been located on the bacterial chromosome. Two mutant strains of B. subtilis 168, which produced tailless phage particles upon mitomycin C induction, were shown to carry lesions, designated xtl-1 and xtl-2, which were linked by transformation and PBS1-mediated transduction to metC. The link-age relationship between xtl and adjacent auxotrophic markers was determined by three-factor PBS1 transduction, the suggested order of markers being argO 1 metA metC xtl.

摘要

一种由枯草芽孢杆菌168携带的缺陷噬菌体PBSX的杀伤活性相关遗传标记已定位在细菌染色体上。两株枯草芽孢杆菌168的突变株,在丝裂霉素C诱导下产生无尾噬菌体颗粒,被证明携带名为xtl-1和xtl-2的损伤,通过转化和PBS1介导的转导与metC相连。通过三因子PBS1转导确定了xtl与相邻营养缺陷型标记之间的连锁关系,标记的建议顺序为argO 1 metA metC xtl。
