Protoplasmic Incompatibility: Possible Involvement of Proteolytic Enzymes

Nature New Biology volume 235, pages 56–58 (1972)Cite this article

Abstract

THE failure to form heterocaryons between non-isogenic strains in fungi, which has been reported for many species, results from protoplasmic disintegration that quickly follows hyphal fusion. Genetic control of this heterogenic incompatibility has been investigated especially in the Ascomycetes Neurospora crassa1 and Podospora anserina2. Cellular (or protoplasmic) incompatibility always arises from a very specific interaction between two genes. Allelic mechanisms, when antagonistic genes are allelic, are found in the two species. In Podospora anserina, however, three incompatibility mechanisms, c/d, c/e and r/v, involve genes of unlike loci3,4.
