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