Wild-type bacteriophage T4 is restricted by the lambda rex genes

The bacteriophage T4 rII genes and the lambda rex (r exclusion) genes interact; rll mutants are unable to productively infect rex+ lambda lysogens. The relationship between rex and rll has been found to be quantitative, and plasmid clones of rex have excluded not only rII mutants but T4 wild type and most other bacteriophages as well. Mutations in the T4 motA gene substantially reversed exclusion of T4 by rex.
