Abstract

The early functional mutants of lambda, belonging to cistrons N, O, and P, are known to be blocked prior to vegetative multiplication of the lambda genome. Superinfection of heteroimmune defective lysogens by these mutants failed to elicit the function required for replication of the superinfecting phage. The mutants among themselves also showed poor cooperation on a nonpermissive host. Studies on the effects of different multiplicities of infection for bacterial lysis showed identical responses for mutants of different cistrons.

摘要

λ噬菌体的早期功能突变体，属于顺反子N、O和P，已知在λ基因组营养繁殖之前就被阻断。这些突变体对异源免疫缺陷溶原菌的超感染未能引发超感染噬菌体复制所需的功能。这些突变体之间在非允许宿主上也表现出较差的协同作用。关于不同感染复数对细菌裂解影响的研究表明，不同顺反子的突变体有相同的反应。
