Differences in RNA related to the intersterility of wild type strains of Ascobolus immersus (author's transl)]

Fractionation of total RNA prepared from intersterile wild type strains of Ascobolus immersus revealed the existence of differences at the 4S and 5S levels which may be related to the polymorphism of these species or sub-species, bearing the same name and coasting along in nature.
