The incompatibility relationships between geographical races of Podospora anserina

V. Biochemical characterization of heterogenic incompatibility on cellular level

  • 27 Accesses

The physiological action of heterogenic incompatibility between the geographical races s and S, which differ by a single gene and a corresponding cytoplasmic factor, has been studied. Microscopical, cytochemical, and enzymatic investigations have revealed that the cell disintegration occurring after anastomosis of incompatible hyphae under the immediate influence of the cytoplasmic factors leads to a destruction of cellular compartments which is followed by a liberation of catabolic enzymes. These incidents are counteracted by regenerative processes.
