Infection of the temperature‐sensitive E. coli CRT 266 ( dna B ts ) with T3‐phages at the temperature of 30°C and 35°C, respectively, induced T3‐specific RNA synthesis with a maximum rate at 7 min (30°C) and 4.5 min (35°C) afte infection. At temperatures above 40°C no T3‐induced RNA synthesis could be observed. Infection of E. coli CR 34–45 ( dna B + ) with T3 phages at 30°C, 35°C and at temperatures above 40°C, however, produced T3‐specific RNA synthesis. The maximum of T3‐induced RNA synthesis could be observed between 7 min and 3 min depending on the temperature during infection. The inability to form T3‐specific RNA after infection of E. coli CRT 266 at nonpermissive temperatures may be a cause for the absence of the formation of T3 phages and lysis of the host cells.
