title: Loss of rRNA genes during a phenotypic, masculinizing mutation in Allomyces arbuscla.
abstract: Saturation hybridization of 3H rRNA from Allomyces arbuscula Bali wild-type to homologous DNA and to DNA preparations from Allomyces arbuscula Bali X-ray induced male mutant and an interspecific male hybrid (Allomyces arbuscula X Allomyces macrogynus Emerson and Wilson) has shown approximately 50--60% reduction in the cistrons coding for rRNA in the masculinized strains.
