title: Analysis of spontaneous deletion mutants of satellite bacteriophage P4.
abstract: Spontaneous deletion mutants of satellite bacteriophage P4 have been isolated and characterized. All of the deletions analyzed that were between 850 and 1,700 base pairs long are within the region nonessential for P4 lytic development; some of them cover the cII or the gop locus.
