Summary

The physiological reaction of heterogenic incompatibility occurring between different geographical races of the Ascomycete Podospora anserina has been studied using the special technique of mixed culture.

The protein spectra of strains differing either by genes of the allelic mechanism or the non-allelic mechanism or by both have been analysed. The results allow a biochemical distinction between the mechanisms. The joint action of both mechanisms leads to the formation of a specific protein. The origin and significance of this “incompatibility protein” is discussed.
