Summary
Treatment of mycelial fragments with EMS and NMU yielded 15 revertants of the pleiotropic mutant zonata of Podospora anserina. Analysis by biological, biochemical and genetical methods has revealed that the reversions are caused by back mutation within the zonata locus. This leads to the conclusion that a point mutation causes the morphological and biochemical alterations in this mutant.
A working hypothesis for the primary action of this gene and its significance for the elucidation of morphogenesis and of pleiotropism are discussed.
