An Acholeplasma laidlawii variant has been isolated that has a REP/sup -/ phenotype. The properties of this variant, relative to parental cells, are: it exhibits no change in cell growth kinetics; it does not propagate single-stranded deoxyribonucleic acid (DNA) mycoplasmaviruses but does propagate double- stranded DNA mycoplasmaviruses; it converts parental circular single-stranded mycoplasmavirus DNA to double-stranded replicative forms that are not replicated further; it exhibits no change in host modification and restriction; and it has an increased ultraviolet light sensitivity. The REP/sup -/ isolate is the first stable mycoplasma variant to which a physiological defect has been attributed.
