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.
