T1 BACTERIOPHAGE PRODUCTION IN ESCHERICHIA COLI

Feiner, Rose R. (Columbia University, New York, N.Y.)and Solon A. Ellison . T1 bacteriophage production inEscherichia coli . J. Bacteriol.85: 7–11. 1963.—Progeny released from complexes formed between unirradiatedEscherichia coli strain Bs-1 and ultraviolet (UV)-irradiated phage T1 were equally infective for strains B and Bs-1, and were therefore not hostmodified. The capacity of Bs-1 for unirradiated or irradiated T1 is relatively insensitive to UV irradiation, as compared with that of strains B and B/r. In all three strains ofE. coli , B, B/r, and Bs-1, the UV sensitivity of the capacity for phage T1 is independent of the UV sensitivity of colony-forming ability. These findings are discussed in relation to the partial genetic homology hypothesis.
