  • Title: Some acridine-resistant mutations of bacteriophage T4D.
    Author: Rappaport H, Russel M, Susman M.
    Journal: Genetics; 1974 Oct; 78(2):579-92. PubMed ID: 4615039.
    Abstract:
    Three new 9-aminoacridine (9AA) resistant mutations of bacteriophage T4D have been isolated and characterized. Two of the mutations, rs and rc, have identical patterns of acridine resistance, but they map on opposite sides of the rII region. In addition, rs has an effect on the plaque morphology of r mutations, whereas rc does not. The third mutation, ama, maps very close to rs but exhibits a different pattern of resistance to 9AA. None of the three is resistant to acridines by virtue of reduced permeability. Taken together with other mutations that have been previously characterized, these new mutations permit us to set the minimum number of acridine-sensitive processes in T4 development at four.
