title: sub, a host mutation that specifically allows growth of replication-deficient gene B mutants of coliphage P2.
abstract: Bacteriophage P2 normally requires the products of its early genes A and B for lytic growth in its host, Escherichia coli C. A host mutation, sub-1, which allows P2 to grow without a functional B gene product is described. The sub-1 mutation is recessive and maps at approximately 10 min on the E. coli genetic map.
