Abstract

Under conditions where the reversion of an amber mutant of bacteriophage lambda by gamma-rays is enhanced by subjecting the irradiated phage to SOS repair, gamma-ray-induced reversion of two T7 ambers is not influenced by this error-prone bacterial repair system. The survival of T7 gamma-irradiated under anoxic conditions is somewhat enhanced by SOS repair, whereas the survival of phage irradiated under oxygen is not affected.

摘要

在通过对受辐照噬菌体进行SOS修复可增强γ射线对噬菌体λ琥珀突变体回复突变的条件下，γ射线诱导的两种T7琥珀突变体的回复突变不受这种易出错的细菌修复系统的影响。在缺氧条件下受γ射线辐照的T7的存活率通过SOS修复有所提高，而在有氧条件下辐照的噬菌体的存活率则不受影响。
