Cytoplasmic mutations isolated from protoplasts ofPodospora anserina

Abstract

SUMMARYSorting out of cytoplasm determinants can be achieved inPodospora anserinaby the use of protoplasts. In this way four cytoplasmic mutations have been isolated. These mutations affect a precise stage of development of the fungus. In crosses with wild-type strains, the mutants show maternal inheritance when no cytoplasmic contact precedes fertilization. However, when cytoplasmic mixing occurs before fertilization, the cytoplasmic wild-type factor shows dominant and/or suppressive properties over the mutant factor.
