title: Superinfection exclusion by bacteriophage T7.
abstract: Only two of the early genes of bacteriophage T7 were found to play a significant role in exclusion of superinfecting bacteriophage T3 particles; genes 0.3 and 1. Protein synthesis by the preinfecting phage particle was not required for efficient exclusion. These findings are discussed with regard to the known functions of these genes during T7 development.
