Evidence of a chemical factor involved in the control of sexual development in the light leaf spot fungus pyrenopeziza brassicae ascomycotina

, : Evidence of a chemical factor involved in the control of sexual development in the light leaf spot fungus pyrenopeziza brassicae ascomycotina. Transactions of the British Mycological Society 87(2): 303-308

Experiments using polycarbonate membranes and ethanol extracts of fungal cultures showed that sexually fertile, paired cultures of the heterothallic ascomycete Pyrenopeziza brassicae produced a factor(s) which can promote the development of the sterile material of apothecia and depress asexual sporulation in single, unpaired isolates of the fungus. This property is specific to paired cultures; extracts of single mating-type cultures and mixtures of extracts of cultures of opposite mating types were ineffective.
