Abstract
Bacteriophage release in a lysogenic strain of
Agrobacterium tumefaciens
V-1 is temperature-sensitive. At 25 C and 30 C, phage was released in a ratio of 1 plaque-forming unit per 100 bacteria; at 35 C, although bacterial growth was not inhibited, phage release was suppressed. Phage synthesis was induced by heat shock, 42 C for 30 min, ultraviolet irradiation, and mitomycin C. Induction by ultraviolet light was unusual—an immediate rise in phage titer followed irradiation. A large increase occurred after a 90-min latent period. The lysogenic strain was cured of the phage by incubation at 37 C, and the cured strain produced plant tumors.
