title: Protoplasmic incompatibility and female organ formation in Podospora anserina: Properties of mutations abolishing both processes.
abstract: A genetic block, effective only with the addition of mutations in two genes, suppresses both the incompatibility process in strain confrontation ("barrage") and the formation of female organs. Investigation on this block lead us to propose that it operates at the ribosomal level and prevents the translation of the messenger of a proteolytic enzyme, a postulated early protein in protoperithecia differenciation.
