Bacteriophage lambda repressor allelic modulation of the Rex exclusion phenotype.

Canadian journal of microbiology - 1 Mar 2003

Slavcev Roderick A, Bull Harold J, Hayes Sidney

Abstract excerpt

The sensitivity of delta red-gam delta ren mutants of bacteriophage lambda to Rex exclusion by lambda rexA+ rexB+ lysogens is modulated by the prophage cI repressor allele. We show the following: (i) lambda spi156 delta nin5 forms plaques on a cI+-rexA+-rexB+ lysogen with 10(5)-fold higher efficiency than on cI[Ts]-rexA+-rexB+ derivatives. (ii) The cI[Ts]857 allele augmentation of Rex exclusion is recessive to...
