Strains of Escherichia coli C or K lysogenic for the non-inducible phage P2 show a lower survival following X-ray irradiation as compared to nonlysogenic strains. This difference in X-ray sensitivity is not accompanied by a significant difference in X-ray induced mutability. The capacity of X-irradiated P2 lysogens to multiply any of a number of unirradiated infecting phages is severely impaired. These effects of X-ray treatment can be most simply explained as a consequence of the fact that protein and RNA syntheses are strongly inhibited in P2 lysogens after X-irradiation. All the above events specifically occurring in X-rayed P2 lysogens are dependent on the P2 gene old.
对不可诱导噬菌体P2呈溶原性的大肠杆菌C或K菌株，与非溶原性菌株相比，经X射线照射后的存活率更低。X射线敏感性的这种差异并未伴随X射线诱导的突变率出现显著差异。经X射线照射的P2溶原菌繁殖多种未照射的感染噬菌体的能力受到严重损害。X射线处理的这些效应可以最简单地解释为，X射线照射后P2溶原菌中的蛋白质和RNA合成受到强烈抑制。在经X射线照射的P2溶原菌中特异性发生的所有上述事件都依赖于P2基因old。
